hey thanks for the advice. what if i want some nice looking gravel (does lowes/hd sell it)? i know it's my first one, but i really want a nice looking tank.
the canister does have some of those rings in it already, should i replace them? top 2 layers have the foam filter pad stuff, 3rd has small gravel, and 4th bottom one has the rings. i think i will get a test kit though. and stability? can i find that at a pet/fish shop? or just let my tank run for a week or so...
