soon to be setting up my 20 gal tank. Its base is 30x12" (H = 18"). I am after a depth of roughly 2" all over of substrate.
I am thinking one of the following (based on sizes of packs available):
30lb fluorite + 4 1/2lb terralit
15lb flourite and 11lb terralit
i would rather buy too much substarte than not enough, as i have other tanks i could add it to, but i am also interested in peoples opinions about the amounts of each? would the second option give me a better mix? and would it be enough substrate all together or would it be a bit thin?
any advice appreciated
