I am having some difficulty with the ph in my reef tank. My sump ph is 8.2 to 8.3. But my display ph is 7.4 to 7.5. I don't understand how they can be so different and why I can't get them to equal. Please help with suggestions.
Tank stats
125 gal display
35 gal sump/refugium
Mag 12 return pump
Pc lights on 9 hours a day
Sump light on 15 hours opposite display
Had lights at 12 and 12 with same ph results.
