Measure your stand opening, and the space in there. Make sure you can fit it, I had to put mine in and then turn it, but in my awesome genius planning i figured almost everything, except that when you turn the sump it gets a little taller , ooops, had to cut the stand a little anyway, didnt like using a jsawzall 2" below my glass. I got it in there. Maesure twice cut once???? lol at myself. Any size sump is better than no sump at all.
