Happy Holidays!
A little history, I just purchased a lab grade Neptune pH probe on Black Friday and it has been calibrated and gave stable readings of 8.04 to 8.16 night and day.
I recently installed an Algae Turf Scrubber and seeded it with Ulva algae on Dec. 16th.
Since then my pH has crept up to 8.07 to 8.46.
I am considering buying new pH calibration fluid and re-calibrating my new pH pen.
I do two parts dosing and have not increased my Alk dosing for at least a month.
When I installed the Turf Scrubber, I immediately took down my GFO reactor which worked great at keeping my phosphates down at 0.02 to 0.1. (Hana ULR phosphorus tester)
Now my phosphates have crept up to 0.34 in about 10 days!
Here is my ATS on Dec. 15th.
Here is the ATS on 12/23/18
Here is a snap shot of my pH from Dec 18th to Dec 24th, 2018.
It does appear as more algae grew the pH slowly crept up.
Can pH really be this high?
Thanks for your help!
