Hello Vern I know my tap water is soft but I wish I had yours. I would be playing with all of the more harder things to spawn like T. Candidi and any Dicrossus species. I can get water with a pH that low if I use a very heavily planted tank, then my pH drops because of the plants. If you need to buffer up without using any chemicals to get a higher pH throw a few pieces of dolomite into the tank. I do this for my livebearers to just barely raise the pH and hardness. I don't know how that will affect the eggs hatching for most of your apistos but somethings might not like it THAT acid.
