Ok, I have a 28 gal planted tank with one bag, 20 pounds I think, of Seachem's flourite. I feel that the substrate is too thin and I have an extra 20 pound bag of "Tihitan moon sand", so I was wondering if it would be better to just buy another bag of flourite (tight budget tho) or should I mix the existing flourite and the new sand, or should I layer them? Mainly, what would be best for the plants (and looks) from this situation.
Oh yea, heres a pic of it currently. Getting some new plants soon, pending a trip to that fish place.
