>The tap water here in Minneapolis hard with a pH of about 8.2. I mix >straight RO with about 5% tap. Adding the tap water provides a little bit >of buffering capacity to the water. So the only buffering you use is the small amount of tap water and you don't use additives to lower the pH? 6.0 to 6.5 pH would be what I'm looking for, so do I remove the peat granules and find that mix of tap to RO that works? OR Should I keep the peat and find the RO/tap mix that works? >I mixed too much tap into the water of one of the pairs and the pH drifted up to 7.8. >Pulling the eggs and adding a double dose of meth blue allowed 30 to hatch >and grow out. This result knocked a hole in the pH testing I did last year >to find the best pH for hatching rams. At that time I was getting pretty >much a zero hatch, and survival rate, above 7.0. Are the tank raised rams being acclimated to a higher pH as have Angels and some others I've been seeing. By the way, the rams you provided in July are ready for spawning and I'm trying to get everything right for their offspring. Thanks for your help once again!
