So I finally determined the cause of my low ph. I have a RO/DI unit so I make all of my own water. I tested the ph of my saltwater about 24 hrs after I mixed it and it tested around 7.8. The same ph of my display tank. So this brings me to the conclusion that my house water has low ph. I believe this is the reason I have low ph in my display tank, from doing water changes and top offs with water that has low ph. So my question is what is the best way to raise my ph? I thought about using ph buffer on my mixed saltwater to raise the ph before I do a water change? But I'm not sure if I could use the same method for my fresh top off water. I know that lime water raises ph but could I use it even though I don't need calcium supplementation?
