Substrate 101 questions....

Hey guys, I am about to add substrate to my tank but I'm not sure if I'm going about this the right way.

I have a 16G half-moon tank and I bought a 20lb bag of Eco-Complete from the LFS (the owner recommended it and I bought it on a whim).

Is there a rule of thumb as far as substrate goes in lbs per gallon? Also, Eco-Complete bag claims that its nutrient rich. I won't have any stem plants (mainly mosses), in which case should I simply use Eco-Complete or some inert substrate and top it off with Eco-Complete?

I appreciate any help, thanks!

Generally its 1 pound per gallon. If you arent using ANY plants that will go directly in the substrate there is no reason to use any at all. I think you will eventualy want some plants that go in the soil. I tried the same thing in one of my tanks and now the substrate is completely covered in plants. In your case you do not need a nutrient rich substrate for the purpose of this is to feed the roots of plants and encourage healthy growth. So you could put whatever soil you want but I'd still suggest 1lb per gallon or atleast some of the substrate in case you want to do other plants in the future.

Sampster, thanks for your reply and advice.

I understand that mosses don't really need much of anything, let alone nutrient rich substrate, but I was thinking the same thing you were. I may change things up like so many planted tank aquarists do so often. Its better I did it this way I think.

1lb per gallon is good...I don't need to buy more! Thanks!
