So in my wave of trying new things this summer, I am thinking about doing a planted tank. I have been doing freshwater for years, and this year took the plunge to a reef, but i still want a freshwater tank. I have never done a planted tank before, so that's what's I'm going to do. What I am thinking is a 10 gallon tank, with a 2 bulb t5 setup. But I don't know what sort of substrate to use. Anyone have experience in these tanks and have tips?
