This isn't a reef, but it's a nano tank question. I've been thinking of changing up my 20g planted (not the one with the corydoras) and I'm wondering what substrate I should use. I have sand right now but I'd rather use either eco complete or stratum. Which do you suggest? It's just wisteria, dwarf sag, water sprite, and hydrophilia. It's a 20g high so how much do I need?
