Glasscages can make you any sump you want for cheap, don't think there are any around for sale my buddy tried for months to get a 29 and no luck! Or Ebay has tanks that you can make your own, with baffels from Lowe's. I just sold the 36x14x16 to a friend and put a 100gal sump on mine in the garage, with all the equipment out there. No more noise and i can do 50 gal water changes without turning my tank off and no mess in the house!
