My water perameters in my tap water is PH: 7.0, KH: 196.9ppm, & GH: 483.3ppm
In my 90g tank it is, PH: 8.4, KH: 304.3ppm, & GH: 966.6ppm
My question is when I do my water changes, I use the rift lake recipe for the exception of marine salt, I substitute for API aquarium salt for freshwater tanks and isntead of baking soda I I have used the Cichlid 8.2 PH, I tried the baking soda once, and am now trying API PH up. I can NEVER get the PH in my tap water to come even close to my tank water. It usually only goes up to about 7.4 - 7.8. What in the world am I doing wrong. I am so afraid of doing water changes fearing that I may harm my fish. I do change the water at about 50% every 2-3 weeks and would like to do them once a week, but would feel much more comfortable if I could get the PH a little closer to my tank perameters. Also, my GH in my tank. Isn't this too high? I was hoping you guys could offer me some advice based on my tap water perameters what I could better try to get these numbers where they need to be.
Oh, by the way, my tanks consists of 4 yellow labs, 3 peacocks, 2 red fin kadangos, 3 copadichromis azureus, and 2 plecos.
