I test all the time and have not had any major ph swings. Honestly the ph has been pretty stable.

My tap water is really hard 11 dgh with a ph of 7.4. I am shooting for soft water with a ph under 7. My water in my tank after going through the R/O unit 6.4/6.5 ph. The dgh is at 3. 3 being a value I want. The kh is 1 or lower since the water changes after 1 drop. My only concern is the low kh and possible ph fluctuations. I am thinking about using seachem buffers such as the arowana buffer or the neutral buffer. I don’t want to add anymore hardness to the water while still giving the fish and plants the trace minerals they need.

Can I use the easy green all in one to remineralize RO water?
