Reeflowers BioClean II Aquarium Water Cleaner, 34-fl oz bottle

When BioClean products are used, nitrate and phosphate levels of water should be monitored by testing the water once a week. If the levels of nitrate are over 10 ppm and phosphate are over 0.20 ppm, then the daily dosage may be increased to 2 tsp (10 mL). If nitrate and phosphate are below 2 ppm or above 0.04 ppm, respectively, then BioClean II should not be used. Depending on nitrate and phosphate levels, either BioClean I or BioClean III should be used per the table above. UV clarifiers, Ozone, and other equipment or treatments that affect the beneficial bacteria population are not recommended to use in tanks where ReeFlowers BioClean products are used. If the recommended dosage is exceeded or if the right biological conditions form, then the bacteria population may suddenly bloom, creating cloudy water. This will not harm your living organisms, but if this situation occurs, discontinue dosing BioClean until the cloudiness disappears. The cloudiness should disappear on its own within 48 hours on average. Do not turn off your filters during a bloom, as the oxygen needs are higher during the bloom and the circulation provided by the filters is needed. You may continue to you the product once the water returns to normal.
