Raise ph solution

An ngo · Oct 8, 2019

My tank 100 gal run from February, using Apex to keep track some dosing and ph. As I just put some lps sps in my tank last week. Torch, hammer fully open, frogspawn kind of sad over a week and never fully open like hammer and torch. Monti and strawberry shortcake still good. The only issue I try to fix is Low Ph. My ph stay from 7.6-7.8 over 3 months. I try kalwasser before but still didn’t able to raise up over 7.8. My kh arounf 7.8-8.
The weird thing I notice whenever temp goes up, ph raise up too which bot like what I read when temp too high, too much co2 then ph will be low. Which is the best way for me to raise it up?????

did you try a co2 scrubber. I have had some success with my co2 scrubber. i'm testing running a airline outside on spare tank. started ph at 7.0 and after an hour 8.0. my dt is farther distance than the other tank. plus im using a crappy skimmer on the other tank that's closer to the window.

When temp/ph goes up, is it because your air conditioner is not on in the house or you have people get home from work/school?

Temp and PH are directly related. That is why the temperature sensor should be next to your PH sensor and you should calibrate PH based on the temp sensor.

Besides that, my guess is that it has nothing to do with a lower PH but with something else. PH is related to oxygen en CO2 in the water. You can raise it with some chemicals but it’s a bad thing to do. Way better is finding out what lowers it.
If you have a skimmer, the air it’s pulling might be CO2 rich. In that case, open a window...
You could put a CO2 scrubber but that would only be to aim for a higher number. Changing it might do more damage than leaving it on a lower value.
