I have a 5 month old tank that is always running on the low side of the PH scale (7.8-8.0). The only way I have been able to get this up is with Kalkwasser in my ATO, but doing this is putting my dKH up in the 11's. I have a simple softie tank so no real demand for Calcium, Magnesium, etc. I am using Red Sea Coral Pro salt and all of the parameters look good otherwise. Any thoughts on how to get out of this? Is 11+ ok to keep the tank at? I lost some softies recently and was assuming that this was part of the problem.
