I have a Coralife SS 220 and i love it. The only problem is that its too tall to put in the sump under my 120g. AGA makes there stands a little short and it was like an inch short of fitting the sump, so now its hanging on the side and i actually find it working better where it is now than when i had it in the sump of my old tank. That shouldn't be a problem for you though because you have a smaller tank so you will be using a smaller model than i am.
