raising ph

[MOD]

good afternoon all I know my ph problem is co2 related. I have 90 gal. tank a 20 gal sump with a fleece roller and an aqua max hang on the back skimmer. MY ph was around 7.6. I ran a line from my skimmer outside this raised it so at peak would get to 8.03 to 8.07. I have tried to figure a way to get more fresh air into the tank. the idea i came up with was to get a replacement skimmer pump and bubble plate and run that in my sump with the airline running outside. I would thank anyone with thoughts on this.

It's almost impossible to have a pH of 7.6 unless you have an aeration problem, have massively overstocked the tank, have an additive that is lowering pH, or the house air is so contaminated with CO2 that it's unhealthy for humans.

You may have a measurement issue...how are you measuring your pH.

I add a Lee's air stone tied and tucked into a pvc t fitting and run air through that before my baffles in the sump and it help dramatically
