3rd chamber on CO2 reactor?

[shiftline]

I lost a bunch of sps a while ago. I have no idea why. Only big change is lower ph. So may be pointless but if I can get it back over 8 I think my tank would be happier.

I did some testes of the effluent after my main. Single chamber reactor then after my diy add on chamber and the ph is about 0.25-0.27 higher

After reactor


After second add on chamber


I also observed the ph slowly climb as the effluent sat in a cup. Adding an airline to the cup accelerates this. Which makes me think of maybe add a settling chamber with an air stone. Or output effluent in front of skimmer intake. Maybe be stage 3
