PH issue!!

[Diesel]

PH issue!!
Have a 202 gallon SPS tank running now for a year.
Full zeo.
I dose two part BRS.
ALK, 8.3
CAL, 440
MAG, 1420
PO4, 0.03
I know during the winter the PH will drop any way a bit but my PH is starting in the morning at 7.68 and will go up to 7.95 sometimes 8.
On good days I open up a window but that makes no difference so far.
Don't want to ad any stuff to my tank as corals still doing good but I'm worried for the long term.
I know you can hook the skimmer up to a CO2 scrubber but what is the best way to do that?

Thanks in advance!

CO2 scrubber would be the answer, all you need is some plastic tubing, a plastic bottle, and soda lime. Drill 1 hole in the cap for the tubing that connects to your skimmer, drill a bunch of holes at the bottom to allow air intake, fill with the soda lime (pellets).

Cool, how much pellets do I ad and how big of a bottle, how long do these pellets last?
I'm sure till I see the PH going up again, but of course I have no idea.

Your lucky, my ph is too high and I don't even dose anything.

I fill up a normal size vitamin water bottle with pellets and that last almost 2 weeks.

where does the plastic tube connect to?

I’m not convinced you have a pH problem.


How are you measuring pH? If you are using a probe, when was the last time you calibrated it?

And here is the all important question, how does the tank look….corals and fish? If they are doing fine, no problems.

A small trickle of ozone could do wonders but that doesn't coincide with the zeovit method. CO2 scrubber is best bet.
