Ph!!!

The dollars usually turn to plants when not getting much other food, I have had them wipe out filamentatious algae removed from a plant tank when I was away for the weekend. They also find certain species, eg hygro IME more palatable than others.

Once those severums and dollars start growing, you may find yourself short a few neons.

Great attitude regarding the advice spiff. Fortunately most folks here share it. Beware absolutes-in aquariums and multiple choice tests.

I agree with the rest-don't sweat the pH unless you are trying to breed a difficult species for example. Stable is best. I have heard/read somewhere that pure R/O is not suitable w/o mineral supplements of some sort-rumor or fact- I am not sure. No experience with it myself.
