Looking for help with choosing a backdrop plant for a curtain style effect along the back of my tank. Currently have Vallis in there but it isn't doing too well. In fact I've never had much success with it. Running with about 2WPG. Currently using EasyCarbo with no injection (since I can't afford it). Any ideas welcome, thanks! Edit: Should mention that I have a plant subtrate and am experimenting with EI dosing.
