I'm trying to determine which cichlids to stock. I'm trying to decide between Mbuna or Julies. My LFS stocks both. I asked them about the ph a while ago, due to reading that they are sensitive to shocks. My LFS keeps their tanks at a ph of 7.2, but my tap water is 7.6. Would they be okay with that much of a change? Do I need to soften the water a bit? Do I need to put some limestone in instead? I'm currently working to get a pond built this summer, and once I do then the 90g will be converted after the goldfish move to the pond.
