Pond test kits. Testing your pond water regularly is the best way to ensure optimum water quality and healthy fish. We carry pH, Ammonia, Nitrite, Nitrate, Alkalinity and Copper test kits as well as Salinity and pH meters.
You can use rainwater to fill your pond, but keep in mind that it is very soft water. If you primarily use rainwater, be sure to check your pH regularly because it could become too low and cause serous problems.
