Chemiclean Instructions: A Comprehensive Guide
Chemiclean effectively targets cyanobacteria and organic waste, restoring a balanced aquarium ecosystem. This guide details proper use, from preparation to post-treatment care, ensuring optimal results.
Successful treatment typically takes 48 hours, oxidizing organic matter and promoting a healthy enzymatic balance within your aquatic environment.
Understanding Chemiclean
Chemiclean, produced by Boyd Enterprises, is a specialized aquarium treatment designed to combat problematic cyanobacteria – often appearing as reddish or slimy growth – and accumulated organic waste. It’s not a typical algaecide; instead, it functions by dramatically increasing oxygen levels within the aquarium, creating an environment unfavorable for cyanobacteria proliferation.
This heightened oxygenation isn’t simply about suffocating the cyanobacteria. It actively oxidizes the organic compounds that fuel its growth, effectively breaking down the source of the problem. Furthermore, Chemiclean promotes a beneficial enzymatic balance, contributing to a healthier, more stable aquarium ecosystem long after the initial treatment is complete.
Understanding this mechanism is crucial. It’s not a quick fix, but a catalyst for restoring natural biological processes. The treatment period, typically 48 hours, allows Chemiclean to work systematically, addressing both the visible symptoms and the underlying causes of cyanobacteria blooms and organic buildup. Proper preparation and post-treatment procedures are vital for maximizing its effectiveness.
What is Chemiclean and What Does it Do?
Chemiclean is a powerful, yet carefully formulated, aquarium treatment specifically engineered to eliminate cyanobacteria – commonly known as red slime algae – and dissolve accumulated organic waste. Unlike traditional algaecides that can disrupt the delicate aquarium balance, Chemiclean works by dramatically increasing dissolved oxygen levels within the water column.
This surge in oxygen initiates a process of oxidation, effectively breaking down the organic compounds that sustain cyanobacteria growth. It doesn’t just kill the visible algae; it targets the root cause, removing the fuel source. The product also actively encourages a healthy enzymatic balance, fostering a more stable and thriving aquatic environment.
Essentially, Chemiclean doesn’t simply mask the problem; it actively restores the aquarium’s natural ability to maintain itself. It’s designed to remove staining caused by cyanobacteria, leaving your tank cleaner and healthier. The treatment period allows for complete oxidation and a return to optimal water quality.
Targeting Cyanobacteria and Organic Waste
Chemiclean’s primary function is to aggressively target cyanobacteria, a resilient type of algae often appearing as a reddish or dark film on aquarium surfaces. This isn’t merely aesthetic; cyanobacteria compete with beneficial organisms for resources and can release harmful toxins. Beyond algae control, Chemiclean excels at dissolving accumulated organic waste – detritus, uneaten food, and decaying matter – that contributes to poor water quality.
The treatment’s oxidation process breaks down these organic compounds into simpler, less harmful substances, reducing nutrient levels that fuel unwanted algae blooms. This is crucial for maintaining a stable biological filter and preventing future outbreaks. By eliminating both the visible algae and the underlying organic load, Chemiclean addresses the core issues contributing to an unhealthy aquarium.
It’s important to understand that Chemiclean doesn’t just suppress growth; it actively removes the source, promoting a long-term solution for a cleaner, more balanced aquatic ecosystem. This targeted approach minimizes disruption to beneficial bacteria and invertebrates.
Preparation Before Using Chemiclean
Before administering Chemiclean, meticulously test your aquarium’s water parameters. Calculate the precise dosage based on your tank’s volume, and optionally, remove sensitive invertebrates for safety.
Testing Water Parameters
Prior to initiating Chemiclean treatment, a comprehensive assessment of your aquarium’s water chemistry is absolutely crucial. This ensures optimal conditions for the product’s effectiveness and minimizes potential stress on your aquatic inhabitants. Begin by testing for key parameters including pH, alkalinity, ammonia, nitrite, and nitrate levels.
Ideal pH should fall within the range of 8;1 to 8.4 for most reef aquariums. Alkalinity, a vital buffer, should be maintained between 8-12 dKH. Critically, ammonia and nitrite levels must be at zero. Elevated levels indicate an incomplete nitrogen cycle and could hinder Chemiclean’s performance. Nitrate levels should ideally be below 20 ppm, though higher readings are tolerable.
Furthermore, consider testing for phosphate levels. High phosphates can fuel cyanobacteria growth, potentially reducing Chemiclean’s efficacy. Addressing phosphate issues before treatment is highly recommended. Accurate test results provide a baseline, allowing you to monitor changes during and after treatment, ensuring a successful outcome and a healthy aquarium environment.
Calculating the Correct Dosage
Precise dosage is paramount for successful Chemiclean treatment. The standard recommendation is one scoop of Chemiclean per 10 gallons of aquarium water. However, accurate calculation requires knowing your aquarium’s actual water volume, not just the nominal tank size.
Account for displacement caused by rocks, substrate, and equipment. For irregularly shaped aquariums, estimate volume by multiplying length, width, and height (in inches), then dividing by 231 to obtain gallons. Round up to the nearest tenth of a gallon for accuracy.
For example, a 75-gallon tank with significant rockwork might hold closer to 65-70 gallons of water. In this case, you would use 6.5 to 7 scoops of Chemiclean. Underdosing may result in incomplete treatment, while overdosing could potentially stress sensitive organisms. Always double-check your calculations before adding the product to the aquarium. A little extra care ensures optimal results and a thriving aquatic ecosystem.
Removing Sensitive Invertebrates (Optional)
While Chemiclean is generally considered reef-safe at the recommended dosage, some sensitive invertebrates may exhibit adverse reactions during treatment. This step is optional, but recommended for aquarists prioritizing maximum invertebrate safety.
Consider temporarily removing particularly delicate species like certain shrimp (e.g;, Cherry Shrimp), snails, or specific coral types to a separate, well-oxygenated container with established water parameters. This minimizes potential stress from the treatment process. Ensure the temporary housing replicates their existing environment as closely as possible.
Maintain stable temperature, salinity, and pH levels in the quarantine container. After the 48-hour treatment period and a subsequent water change in the main display tank, carefully reintroduce the invertebrates, acclimating them slowly to the new water conditions. Observe them closely for any signs of distress post-reintroduction. This proactive approach safeguards your valuable invertebrate population.

Administering Chemiclean
Chemiclean is administered by adding one scoop per 10 gallons of aquarium water. Ensure adequate oxygenation, as the skimmer will likely overflow during and after dosing.
Dosage Rate: 1 Scoop per 10 Gallons

Determining the correct Chemiclean dosage is crucial for effective treatment. The standard and consistently recommended dosage is one (1) scoop of Chemiclean for every ten (10) gallons of aquarium water. Accurate measurement is key; underdosing may yield insufficient results, while overdosing isn’t necessarily harmful but offers no additional benefit and is wasteful.
Before adding Chemiclean, calculate your aquarium’s total water volume precisely. Account for rocks, substrate, and any other displacement within the tank. It’s always better to slightly overestimate than underestimate the volume.
For irregularly shaped aquariums, approximate the volume by multiplying length, width, and height (in inches) and then dividing by 231. This provides a reasonably accurate gallon estimate. Once you have the total volume, divide that number by ten to determine the number of scoops needed.
Example: A 120-gallon aquarium requires 12 scoops of Chemiclean (120 gallons / 10 gallons per scoop = 12 scoops).
Remember to use the provided scoop with the Chemiclean product for consistent and accurate dosing.
Adding Chemiclean to the Aquarium
Once the dosage is calculated, carefully add the Chemiclean powder directly to the aquarium. It’s generally recommended to disperse the powder across the water surface for optimal and even distribution throughout the tank. Avoid concentrating the powder in a single location, as this could create localized imbalances.
You can pour the measured Chemiclean directly into the aquarium, or pre-dissolve it in a small amount of aquarium water before adding it. Pre-dissolving can help with faster dispersal, especially in larger tanks. Ensure the water used for dissolving is from the aquarium itself to avoid introducing any foreign substances.
After adding Chemiclean, allow it to circulate throughout the aquarium. A powerhead or wavemaker can assist in accelerating this process, ensuring the product reaches all areas of the tank. Observe the water for any immediate reactions, though none are typically expected.
Important: Maintain normal aquarium operation, including lighting and filtration, after adding Chemiclean. Do not make any significant changes to the system during the 48-hour treatment period.
Skimmer Management During Treatment
Skimmer operation is crucial during Chemiclean treatment. You absolutely want the increased oxygenation that a functioning skimmer provides as Chemiclean works to break down organic waste and cyanobacteria. Prepare for a significant increase in skimmate production – your skimmer will likely go “crazy” and overflow.
Before dosing Chemiclean, remove the skimmer cup and allow it to overflow directly into the sump. This prevents the skimmer from becoming overwhelmed and potentially malfunctioning. Monitor the skimmer frequently during the initial hours after dosing, as the overflow rate will likely be substantial.
The increased skimmate will be dark and foamy, indicating the removal of organic compounds. Do not be alarmed by this; it’s a sign that Chemiclean is working effectively. Continue to allow the skimmer to overflow for the duration of the 48-hour treatment period.
Avoid adjusting the skimmer settings during treatment. Let it run at its normal settings, even if it means constant overflowing. This ensures maximum waste removal.
Skimmer Overflow Expectation
Expect significant skimmer overflow during Chemiclean treatment – it’s a normal and desirable outcome. Chemiclean’s action of oxidizing organic waste creates a substantial increase in the production of skimmate, far exceeding the skimmer’s typical capacity. This is why pre-treatment preparation, like removing the skimmer cup, is essential.

The overflow isn’t a sign of a problem; it demonstrates that Chemiclean is actively breaking down cyanobacteria and detritus. The skimmate will likely be exceptionally dark and foamy, a clear indication of the waste being removed from the system. This process can last for several days after the initial dose.
Don’t attempt to restrict the overflow. Allowing the skimmer to overflow into the sump is crucial for maintaining optimal oxygen levels and preventing the skimmer from becoming clogged. Monitor the sump water level to ensure it doesn’t overflow itself.
Be patient. The overflow will gradually subside as the treatment progresses and the organic load decreases. It may take a few days post-treatment for the skimmer to return to its normal operating level.

Post-Treatment Procedures
Following Chemiclean treatment, a 20% water change after 48 hours is recommended. Monitor water parameters closely and gradually reintroduce sensitive invertebrates to the aquarium.
Water Change After 48 Hours (20% Recommended)
Performing a water change approximately 48 hours after completing the Chemiclean treatment is a crucial step in the post-treatment process. This helps to dilute any remaining oxidized organic compounds and further restore water quality. A 20% water change is generally recommended as a safe and effective measure, but adjustments can be made based on individual tank conditions and monitoring results.
Before initiating the water change, ensure the new saltwater is properly prepared, matching the existing aquarium water in terms of temperature, salinity, and pH. Use a reliable testing kit to verify these parameters. Slowly add the new water to the aquarium, avoiding any sudden shifts that could stress the inhabitants.
The water change doesn’t simply remove residual Chemiclean; it actively supports the re-establishment of a healthy biological filter. By removing accumulated waste products, it creates a more favorable environment for beneficial bacteria to thrive. Observe your aquarium closely after the water change for any signs of stress in fish or invertebrates, and be prepared to adjust your maintenance routine accordingly;
Remember, consistency in water changes is key to long-term aquarium health, even after successful Chemiclean treatment.
Monitoring Water Parameters Post-Treatment
Consistent monitoring of water parameters is essential following Chemiclean treatment to ensure a stable and healthy aquarium environment. Begin testing key parameters – ammonia, nitrite, nitrate, and pH – 24 hours after the 20% water change. Elevated ammonia or nitrite levels could indicate a disruption in the biological filter, requiring immediate attention.
Pay close attention to oxygen levels as well. Chemiclean’s process can temporarily impact oxygenation, so ensure adequate aeration is maintained, potentially through the use of an air pump or increased surface agitation. Regularly check alkalinity and calcium levels, as these can also be affected by the treatment and subsequent water change.
Record your test results diligently to track trends and identify any potential issues early on. If any parameters deviate significantly from their optimal ranges, take corrective action, such as performing additional water changes or adjusting filtration.

Proactive monitoring allows for swift intervention, safeguarding the well-being of your aquarium inhabitants and preventing the recurrence of cyanobacteria or organic waste issues.
Reintroducing Sensitive Invertebrates
Careful reintroduction of sensitive invertebrates is crucial after Chemiclean treatment, as these creatures are often more susceptible to water quality fluctuations. Wait at least 48-72 hours after completing the post-treatment water change and confirming stable water parameters before returning them to the main display tank.
Acclimate invertebrates slowly, using a drip acclimation method over a period of 1-2 hours. This gradual introduction minimizes stress and allows them to adjust to the altered water chemistry. Monitor them closely for any signs of distress, such as lethargy, erratic behavior, or loss of appetite.
Consider starting with a small number of invertebrates and observing their response before reintroducing the remainder. Ensure adequate oxygenation and maintain pristine water quality during the reintroduction process. If any invertebrates exhibit adverse reactions, immediately return them to a quarantine tank.
Patience and observation are key to a successful reintroduction, ensuring the long-term health and survival of your delicate invertebrate population.

Troubleshooting and FAQs
Common concerns include skimmer activity and treatment effectiveness. A crazy skimmer is normal; treatment may take up to 48 hours. Resources are available for further questions!
Why is My Skimmer Going Crazy?
A significant increase in skimmer production is a very common and expected reaction when using Chemiclean. This isn’t a cause for alarm, but rather an indication that the product is actively working to remove organic waste and pollutants from your aquarium water.
Chemiclean’s process releases dissolved organic compounds as it breaks down cyanobacteria and detritus. These compounds create a substantial amount of foam, leading to skimmer overflow. It is highly recommended to remove the skimmer cup before dosing to allow the overflow to proceed directly into the sump without causing issues.
The skimmer is essentially doing its job more efficiently, removing the byproducts of Chemiclean’s cleaning action. This heightened activity typically subsides after the 48-hour treatment period and subsequent water change. Don’t be surprised if it continues for a few days post-treatment as the system stabilizes.
Essentially, a “crazy” skimmer is a good sign! It demonstrates that Chemiclean is effectively targeting and removing unwanted substances from your aquarium.
How Long Does Treatment Take?
The primary treatment period with Chemiclean lasts for 48 hours; During this time, the product actively works to oxidize captured organic waste and restore a balanced enzymatic environment within your aquarium. It’s crucial to allow the full 48 hours for optimal effectiveness, even if you begin to see improvements earlier.
However, the overall process of stabilization and recovery may extend beyond these initial two days. You can expect to see continued, albeit diminishing, effects on your skimmer and water parameters for several days following the treatment.
A 20% water change is recommended immediately after the 48-hour period to help remove the oxidized waste and further support the aquarium’s recovery. Monitor water parameters closely in the days following the water change to ensure stability.

While the core treatment is 48 hours, complete resolution and a return to a fully balanced system can take up to a week, depending on the severity of the initial issue.
What if Treatment Doesn’t Seem Effective?
If you don’t observe significant improvements after the initial 48-hour Chemiclean treatment, several factors could be at play. First, ensure accurate dosage – one scoop per 10 gallons is critical. Double-check your calculations and the volume of your aquarium.
Secondly, verify adequate oxygenation. Chemiclean requires sufficient oxygen to function effectively; a properly functioning skimmer is essential. If the skimmer isn’t producing a robust foam, consider adding supplemental aeration.
Persistent issues might indicate a particularly severe organic waste buildup. In such cases, a second, carefully monitored dose of Chemiclean may be necessary, repeating the 48-hour treatment and subsequent water change.
However, avoid repeated dosing without addressing the underlying cause of the waste buildup. Evaluate your feeding practices, filtration capacity, and overall aquarium maintenance routine. If problems persist, consult a knowledgeable aquarium professional for further assistance.
