Wheres a good place (or person) to get testing kits from, for GH, KH, NH4, nitrite, and nitrate. and anything else i might need for planted aquarium. I know my water isn't anywhere near bad, cause i do my regular water changes. and with like 10 zebra danios, 2 rams... and not much else...pretty sure the volume of 100gal can take anything from my fish.
