Valerie, For my Cockatoos in the 10 gallon the water is straight tap water in the high 7s. They may not breed, but Cockatoos are much more tolerant of high ph than other Apistos.
In my 20 gallon long tank I add CO2 with a yeast mixture. The ph is in the low 7s, but I am slowly lowering with the CO2. I did have it at about 6.5 for a few months, but had to raise it back up for the introduction of some new fish.
