Hello,

I have a question. I run CO2 through a Ph regulator, as the tank size I have (240 gallon) doesn't necessarily bode well with drop checker, I had continual algae blooms, BBA, and stunted plant growth. However, my Ph has decided to settle at 6.4- 6.6 without CO2 injection, while my Tap Ph is around 7.2. I'm concerned with dropping my Ph any lower with CO2, as I don't wish for my fish to suffer. I do have discus, rams, cardinals, rummynose, and bristlenose pleco. I've used the rotalabutterfly calculator regarding Ph based on my water parameters, but when I altered my controller to reflect the calculation, my fish seemed displeased.

My question: should I try natural methods to raise my Ph, IE calcium carbonate sand in my sump to gently raise the Ph, so that I can add the Co2 back? or leave well enough alone?

How much water change you do?
I think regular WC will make it.

Also what is your tapwater KH?
