I am starting a new 10 gallon planted tank with a betta fish. The only water I can use is RO
water. I am on a well and water smells like rotten eggs. (smell of cold water is almost not noticeable but hot water smell disgusting, I was told there are some kind of Iron eating bacteria that are harmless to people but they produce sulfur smelling gas)
Anyway, I know that pure RO
water is not ideal for fish.
What additive should I use???
My local fish store recommended Seachem Neutral Regulator.
