Perfect for African Cichlids!
My ph is off the scale, somewhere well above 8, and many popular fish do fine in my community tank.
Mollies, platies, and swordtail reproduce and do great in my tanks. Guppies reproduce, but tend to live less than a year, but I cannot be certain this is due to the high ph.
Ghost shrimp also seem to love it, and even they are reproducing (slowly).
Corries and ottos also doing fine for more than a year.
Iv'e had rams for about two weeks now, and they seem to be healthy. I'm keeping my fingers crossed cause I really like these guys.
Personally, I try to find fish that work in my water rather than monkey with the ph. Chances are, if you have high ph, your water is also very hard, making it more difficult to bring down, and generally speaking, stable high ph is going to be better than lower ph which fluctuates a lot.
And you can't believe everything you read, or everything people tell you. My lfs insisted that nothing would survive in my water, and now I sell them the fry I raise in that same water.
