Forgot to ask about it before when adjusting the KH of RO water I have been using Kent Marine Superbuffer-dkh. It contentscarbonate,biocarbonate, and borate salts. Is this the right chemicals to use for a planted tank I used to use it for a reef tank. Does anyone else use this chemicals in adjusting KH??
