A one point reduction in PH is 10 times acidic. This is the basic thumbrule followed. What are you doing with 8.2 that nearly brackish.Sab_Fan;4350412; said:why do you keep your Ph at 8.2? that seems unnecessarily high, and would certainly be at the outer-extreme level for any of the fish you are keeping . . . those aren't African cichlids
if it were my tank, I'd keep the Ph closer to neutral . . . I cannot think of any reason why is should be above 8 . . . is that they way the water comes out your tap?
I'm not saying this is the cause of any problems, but it could be something that has had a long-term negative impact on the fish's health . . . (?)
Reduce your PH ASAP. MAX 7.4 for central american cichlids
