I have a light sand base and have grown plants before and had decent success with swords and vals. I had a DIY CO2 system for a while, but I didn't notice much difference. Fert tabs did work well. After a move, I am starting my tank up with a sand bottom again. Can I put some sort of base material in plant saucers to grow healthier plants? Also, how do I keep the plants from becoming covered with algae? I have a pair of Nerites, but will probably get more to keep the glass clean. I also have some corys and a pair of clown loaches to move the sand. I have more driftwood on the way and love the look of things growing on it. What is the best plant to grown on wood?
