I have a 90g aggressive/LPS tank with a 30g sump. Fuge lighting 16 hr/day, opposite the 12 hour tank lights and their 8hr full lighting period, algae growth is great, nitrate near 0 all the time. Using Kalk with ATK and Apex monitoring. Skimmer is on on a CO2 scrubber 100% of the flow because there are people in the house 24/7.
Ph runs 7.75 to 8.0 daily. Cannot get to maintain above 8.0. If I add anything to increase PH, within 2 days its back to the same.
Alk 9-10, Calcium 380-420, Mag 1300-1340, and all other parameters are great on my testing and ICP. LFS asks why I even have them check the water when I come in, because its always about the same.
How can I get the PH up to 8.0-8.2 daily?
