I am building a 20gal Long planted tank, my very first aquarium. I love the way that red flourite looks on the bottom of the tanks in the gallery, and have done alot of looking around, and the cheapest place I have found it is at big als online, at 22 USD a bag with shipping. Does anybody know a cheaper place I can buy flourite at? I need 2 bags, and I would like to spend under $20 a bag if possible. If I cant, I will have to compromise and go with eco-complete at the LFS.
