Hi, recently I decided that I would like to start a planted tank, in one of my already established aquariums. I ordered proper lighting a T5HO fixture, and bought some Eco-complete for the substrate, I received my substrate and lighting today, I have not purchased plants for my aquarium yet, as I live in Canada, and i'm having a hard problem finding quality here, seeing as i'm new to the hobby. I was just wondering, Would it be okay to use this substrate for a few days before I purchase plants?
