Hi -
Would really appreciate your thoughts on my pH.
This is my pH over the last few days until now. I first calibrated the Apex probe using Fusion then I recalibrated using Apex local on the 18th. You can see the spike and then steady decline.
The tank is just two weeks old and has finished cycle. Ammonia is zero, nitrates are 75 ppm and Alk is 7.8 dKH. I have confirmed my small apartment has very elevated CO2 and have a scrubber incoming. I do not have an option to pull air from outside.
I expected low pH given the above but 7.4 is lower than I expected and am doubting it is real. I’d hate to purchase a $75 pH pen to compare nor an untrustworthy titration test. I may take it to the LFS to confirm.
What would you do? Thanks!
