High pH & Procal

[PMolan]

Hey.. A little while ago I posted about directly introducing co2 into the skimmer to lower my pH. It was working fantastically. co2 on at 8.4, off at 8.35. Great. Santa was nice to me and I got a MTC Procal. It recomends 1 bubble/sec and flow of .05. Got it dead on balls accurate. I have effluent of pH-6.5 and Alk-35. So far everything matches what it is supposed to be. HOWEVER.. My tank is now pH 8.75 and 10 dKH. Grrrrr. Dosing vinegar seems to bee a temporary fix. Can anyone recommend an adjustment? Total water volume is ~350 gallons. Thanks.

Edit:
Just thinking.. Could I double the bubble count as long as I double the flow?

Well I really didnt want to screw with the reactor and flow. I looked for alternate ideas and forund a co2 manifold. Basically a 2 way splitter. One for the reactor at 1-b/s and one for the skimmer. I rigged something up like this last night with some john guest T's and so far so good with the results. pH at 8.43 right now.

I wish I could get my PH to 8.4, let alone struggle for it not to go higher. What salt are you using? How much kalk are you dosing? What's your dKH?

I don't know which salt I am on today. I think the blue bucket ???. No kalk, and last night dKH 10. I'm beginning to truely believe it is all of the house plants my wife keeps that keeps the co2 down in the house. Out of all the sites I read on pH, all of them say it is a co2 deficiency. LOL.. Just sitting on my couch and not really looking hard, I count 16 plants :
