I'm trying to get my pH up to around 8.0-8.2, I'll be switching all my juvenile ac's to my new 50g tank soon. After looking over the tank and taking a role call I found out it wasnt the new lab that passed away. It was one I've had for around 2 weeks. My 2 Johanni are probably the smaller of all my cichlids, One being about 1.75" and the other about 1.50". I'll be monitoring behavior and once the switch is made to my 50g, I'll be stacking flatrocks for my rockworks. Any tips on what type of flatrock to use?
Continuing adding crushed coral but slowly. A pH fluctuation can severely stress some fish, leading to health issues. Doing it slowly is fine, and using calcareous material like coral (dolomite, marble chips also work the same) is the best way to raise hardness and pH, and you are correct that it should be higher for rift lake cichlids.
The KH of your water is probably low which is why the pH of the tank water is slowly dropping. The calcareous coral will help right this. And the rift lake cichlid mix you mentioned earlier will also help.
