For normal cleaning and to maintain a clean aquarium: Add 20 ml (4 capfuls) per 25 US-gallons (94.6 L) [≈16 drops per gallon (3.8 L)] of aquarium water weekly.
For problem aquariums or to rapidly accelerate cleaning: Add 30 ml (6 capfuls) per 25 US-gallons (94.6 L) [≈24 drops per gallon (3.8 L)] of aquarium water on the first day, then add Add 5 ml (1 capful) per 25 US-gallons (94.6 L) [≈4 drops per gallon (3.8 L)] of aquarium water daily for 2 weeks or longer as necessary until desired results are achieved.
Bacteria work slowly, so full results can take up to 8 to 10 weeks for long neglected systems.
Turn protein skimming and UV-sterilization off for a period of 4 hours following addition to aquaria. While utilizing MicrōBacterCLEAN continue good maintenance practices such as regular vacuuming, using purified water for additions, and limiting the addition of unnecessary nutrients
Failure to maintain adequate nutrient content in any reef system may result in bleaching and/or tissue degradation of zooxanthellate invertebrates.
