Sulit! Great value. In the US API test are respected. Perfect for starting your system and for on going maintenance especially for those using biological filters - including aquaponic system owners. This has 5 test: pH, High Range pH, Ammonia, Nitrite, Nitrate. Since I use this for an aquaponic system the only other test I wanted was for dissolved oxygen.
