Kh And Ph Levels.

[chief hill]

Well my levels seem off.
Salinity 1.25
Ph 7.9 end of the day
KH 11.8
I am assuming that this may be due to elevated co2 levels. Summer all windows closed tank is sealed up pretty good. So I ran an airline outside of the sump area and opened the windows in the house for the night to see if it helps.
Anyone else have issues with co2 levels and pH?
I have kalkwasser but don't want to use it because the kh is high.

I don't have a test kit for that yet. Will be picking one up tomorrow.

Growing macro algae during lights out definitely helps, co2 scrubbing media works very well.
What is your pH just before your lights turn on?

Lights out a couple hrs ago. I'll test in the morning to see. I'll have to monitor.
