That’s fine, I’ve breed wild caught Zaire’s in lower, they will adapt to your water just fine. The key is to keep stable ph, don’t try to rapidly buff it with chems.
According to my city statistics, the water is PH 7.6 - 8.3.
I have been keeping African cichlids for 15 years breeding tropheus, featherfins, cyps, and frontosas with no problems. Good health and breeding. I add nothing but the anti-chlorine stuff.
