Well I bought one at Coral reef aquatics, but it wont fit in my sump. It seems its to tall, I guess i will have to cut a hole in the back of my stand and hang it on the outside of the sump, of course that means I will have to pull the whole thing out farther from the wall. All this is after I rebuild my sump, I broke a baffle trying to get skimmer in. Lesson learned dont use thin glass to build baffles with.
