I have a 29 with java moss and a anubia that has 3 leaves on it. I want to turn it to a planted (heavenly planted) and I want some kind of soil for my tank that is cheap and worth it. Will any do or what, what are the differences and advantages of certain soil? Tank has sand as substrate, can I still keep it? and will it cover the soil well? I only have a desk lamp to light my tank for now. I want to and I want to get a glass top and buy these lights I saw at a store with like 5 LED bulbs each for like $5 and I want to get several to stick them onto the glass and light the tank (lights have a sticky back with rechargeable batterys). What do you guys think about them. Thanks for looking and I will have some pictures of the tank right now. The tank is in its first 2 weeks running.
