AquaCleanse is used to eliminate common chemicals in tapwater that are toxic to fish and other aquarium creatures. These chemicals, such as chlorine, chloramines and ammonia, are in tapwater in order to make it safe for us to drink by killing bacteria, viruses and parasites. However these same chemicals can also kill your fish which is why you need to add AquaCleanse to your tapwater before setting-up a new aquarium and doing routine water changes. AquaCleanse destroys the chemical bonds that form ammonia, chlorine and chloramines. AquaCleanse has no unpleasant sulfide odors.AquaCleanse Tapwater Detoxifier for PondsDosing: Add 5 ml of AquaCleanse per 10 gallons of tapwater and stir the water for 15 seconds. AquaCleanse cannot be overdosed but adding very large amounts of AquaCleanse to your pond may lower the pH of the water if the water is poorly buffered. How to use: When doing a water change it is best to add the tapwater to a clean bucket or trash can (don’t use soap to clean the vessel). Then add the required amount of AquaCleanse, stir and it is ready for use. We strongly recommend against adding tapwater directly to the pond and then adding AquaCleanse if Koi and/or other live stock are present. Chlorine and chloramines are deadly to fish and even a short exposure can be very harmful to your aquatic pets. New aquaria: Newly set-up ponds typically do not have sufficient nitrifying bacteria present to handle the ammonia excreted by the fish in the water. This leads to a build-up of ammonia and, after about 2 weeks, nitrite (see biological filtration for more details) that can kill your fish. This malady is called New Tank Syndrome (NTS). While AquaCleanse can eliminate the ammonia we do not recommend continually adding AquaCleanse to your aquarium. Instead add DrTim’s Aquatics One and Only nitrifying bacteria which has been scientifically formulated to quickly eliminate NTS. 16oz Treats 960GAL or 3634L
