Hello. I actually have a couple questions about plants. Really wanting some amazon swords, java fern, maybe wisteria, and maybe hornwort. Moss balls too off course. 1. I read that carbon in your filter will remove liquid ferts. Is this true? How could I get around it? 2. Pest snails! This is unacceptable if I ever do manage to start live plants. How can I avoid them? I've heard about dips and quarantine. What exactly does this mean? Any other practices? Wouldn't be as worried if I could get a few Assassin Snails. I can't do this though because I have other snails (nerites and a mystery).
