Biozym Pond Filter Cleaner (BB901): A concentrated active cleaner powder. It sticks directly to filter pads, brushes, and sponges to rapidly break down accumulated fish feces, organic waste, and sludge. It drastically cuts down how often you need to wash out your filter media.  

• Dosage: Use 5 to 10 grams per 1 ton (1,000 liters) of water. A single flat scoop inside the tub is roughly 5 grams.
• Application: Pour the dry powder directly onto your filter brushes or filter cotton. The powder will stick to the organic matter and begin self-degrading the sludge.
• What to expect: You will likely see bubbles forming in the filtration chamber. More bubbles mean the enzymes are successfully breaking down a heavy organic bioload. The water may experience temporary mild turbidity (cloudiness) for a few hours immediately after dosing, which resolves entirely on its own.
• Frequency: Apply once a week for active waste reduction, or once every two weeks for regular maintenance.
