I currently have a 15W light rated at 6700K with a CO2 system for my 10 gallon planted tank, but I'm thinking about changing the gravel to something better for plants. Should I layer the bottom with just Eco-Complete, or should I put a layer of Eco-Complete then a layer of another substrate (such as PFS)? How thick a layer of each do I need to have?
