Preventing under sand fertilizer from mixing
I am upgrading my 50g planted discus tank to a 175g.
I've always used gravel as substrate, but i like the look of sand. It also brings out the best colors in discus.
I am planning to use all sand bottom with fertilizer under it. I am a bit concerned that sand will mix with fertilizer over time. My question is, would it be a good idea to put some kind of mesh (mosquito net) over fertilizer (powersand or peat) and then pour sand on top? The only downside i see is that plant roots would get entangled in the mesh making it hard to replant, but i usually keep my layouts for the life of tank.
Anybody with similar experience, pls chime in.
thanks in advance
P.S. My first post, i think it is a very helpful forum full of knowledgeable and nice people.
