Please Recommend Reliable Test Kits for PH, KH & GH
I really do need a good reliable test kit for my PH, KH and GH now that I'm going to be getting a good CO2 system and dosing ferts. Please let me know what you use and how reliable it's been for you?
The test kits that I currently have are, for PH: Aquarium Pharmaceuticals, I also have a AP Nitrate test kit. For KH and GH: Jungle Labs and I also have Mardel 5 in 1 test strips. I believe that the PH test kit I have is pretty reliable (or at least I'd like to believe it is) but I'm not sure about the rest, so please, I welcome all suggestions!
