This is an interesting discussion: for my tank I have been running on the high side (10.5-11.5) for a year now. I have been thinking of trying to lower it closer to 8.0. I wonder if I should even bother?
I use IO salt, do a 10-15% water change weekly, while ALK is a very consistent parameter for this 75 gal fish and coral tank with a 20 gal sump, which is just starting to grow macroalgae after 3 previous attempts.
Maybe I should just leave it at 10? I use kalkwasser to maintain Ca ~450 and pH ~8.3.
