I set mine up a few weeks ago and LOVE it! It's not fully matured yet. and you can make it out of stuff that you already have, like an old gravel vac. I used a hirota compact light, ($15) and it gave my husband an excuse to buy a dremmel (he's always wanted one!) We used our canister filter (empty) as the return. I'd like a little more flow, but it's ok for now.
