Hello everyone! I am new to this forum and have found a lot of great information about cichlids in general. I currently have a 36 gallon bowfront aquarium with 1 venustus, 1 cobalt zebra, 1 yellow lab, 1 yellow tail acei, and 1 red tail black shark. I recently bought a 75 gallon marineland aquarium that i want to transfer the fish i have into the 75 gallon. My only issue is that my ph in the 36 gallon is around 7.2 which i know is on the lower end for mbuna but they seem to be doing well. When i get the new fish and put them in the 75 gallon, should i try to raise the ph and if so will that effect the 5 fish that i have already? My tap water is around 6.4. Ive read that a steady ph is better than a changing ph. I just dont want the 5 fish i have to die, especially the shark. My girlfriend picked out the shark and she would be very upset if he died. Any help would be greatly appreciated. Thanks!
