Api Freshwater test kit is a MUST for the tropical fish keeper, its one of the most accurate liquid test kits there is, knowing your water params are good gives piece of mind knowing you also have healthy fish, Most important is tank cycling, your filter cycles 1st Ammonia NH4 and then NO2 nitrite, when these to elements are zero you know your filter is working properly. NO3 nitrate is a different obstacle, your filter wont cycle it as its and "end product" of the tank water cycling proccess. Nitrate NO3 can come from three sources,. First directly in the tap water, most areas have some level of nitrate in them, secondly its also can come from over feeding as uneaten food breaks down in the tank cuasing notrates and thirdly from bad tank hygiene, when water changing the bottom of the tank requires hoovering right to the glass at the bottom inder the substrate to remove fish waste and uneaten food, to be honest impossible with sand as a substrate. anything left underneath witll cause high nitrates again bad for the fish. No3 Nitrate levels for standard tropicals must be no higher than 50 parts per million but DISCUS are not as hardy and a limit of 10 to 15 parts per million is a MAXIMUM so take these limits on board when water testing.
