Hi all. I'm getting back into the hobby after several years. Local water has very little buffering capacity. GH and KH are both less than 50ppm. Great for apistos so that is my aim. But first I need to cycle. I am somewhat familiar with this process with normal water conditions. I also am aware of the problems with soft water realizing that a PH crash will occur and will stop nitrification. Should I buffer the water in some way to try and stabilize the PH during cycling. Another question that puzzles me is after cycling and I have a low GH/KH aquarium, what keeps nitrification going. Or, in other words, what keeps the PH stable so the bacteria can do their thing?
