So I’m trying to decide what my water source will be, I’ve kind of been in and out of the hobby for a few years now and recently decided I want to set up a planted 10gal nano tank and stock it with some Pygmy Cory’s, maybe some white cloud minnows or neon tetras? (I haven’t made up my mind yet) I have a 40gal breeder with an African Clawed Frog I rescued that does just fine with my tap water, and currently my 10gal is only stocked with 4 nerite snails.
Right out of the tap my PH is 8-8.2, my KH is 13°, and GH is 20°.
Obviously I don’t want to harm any fish or have them living uncomfortably. So my question is should I get an RODI system and remineralize and/or mix with de-chlorinated tap to lower ph/kh/gh? Thanks you to anyone who has some thoughts!
