This aquarium cleaning solution delivers live bacteria that colonize a tank and break down sludge, uneaten food and other organic debris. As the bacteria consume waste, they help support the natural aquarium cycle and reduce the buildup of compounds linked to ammonia and nitrite poisoning, low oxygen and low pH. The liquid formula is dosed with a measuring cap or teaspoon and mixed directly into aquarium water, with no assembly or equipment needed. It suits both freshwater and saltwater setups, including tanks with rock, coral and gravel where debris is hard to remove by hand. Regular dosing during setup and ongoing maintenance is intended to support a strong biological filter over time. The bottle stores at room temperature and does not require refrigeration.
