I have set up a 55 gallon mbuna tank (Will house Cobalt zebras, Acei and Yellow labs) and a 40 gallon dwarf mbuna tank (Will house Afra and Saulosi) No fish yet, still trying to fishless cycle the tanks. My problem is that my water has a pH of 9.6 out of the tap. gh and kh need to be tested and I'm waiting on a test kit to arrive. I do have a TDS meter and an API master test kit though, TDS is 561ppm. I spoke with an online retailer and told him my situation and he said the mbuna would be fine in my water. This just seems way high for mbuna to me. I know Tanganyikans like a pH that high but I'm hesitant to try mbuna with my water. RO unit is not a possibility due to landlord issues, however buying RO water is an option. What should I do to keep mbuna guys?
