Never bothered buffering my water for malawis but now with trophs and tangs, should I. KH and GH are low. KH is 107.4 ppm and gh is 125.3 ppm on my API kit. Ph is mid 7's in the tank and outta the tap. Coral in both filters and aragonite substrate. Now low KH means unstable PH, correct?. This can mean Ph swings during wc's which is bad, am i on the right track?
Now with the coral and aragonite helping to buffer the water where it's at now would it be ok to leave it alone, or would you guys start buffering. I change 50%, 150ish L on the mon then about 20% on fri. Hose connected to shower and dechlor as it fills. How do i go about adding the buffer? and what is a good recipe for my KH and GH readings. Can i add it as the tank fills, I'm guessing it would need to be lifted slowly on every mon wc over a few weeks to bring the KH up slowly. Any recommendations?
