Hi all. I'm struggling with a low ph. I have a 90 gallon reef tank with a refugium and sump. I have a protein skimmer and I am running a charcoal and GFO reactor to keep my phosphates under control. I have been dosing sodium ash according to BRS calculator to keep alkinity up. I have a 60 gal water station in the basement that does 3 gal/day auto water changes using the DOS. Here are my parameters
PH: 7.6
alk 8.2
Ca: 532
Mg 1600
phosphates 20 ppb
How can I raise the Ph without raises my alk level? I've been reading about CO2 scrubbers but I'm not very familiar with them. Any suggestions? I never had this problem when I was doing 20 gal water changes weekly. I've also read that RO/DI water and saltwater sitting in a barrel can raise increase acid in the water if not airtight. Thanks for the help.
