i've got a QO 2200 coming in the mail and i've got a 29g tank that's just begging for a sump. although i'm very familliar with the theory and ideas behind sumps i've got not hands on experience. just wondering what sumps you guys have got under your 29g tanks and wondering if anybody has any suggestions. since drilling is also not an option at this point i want to know if anybody has some good designs for overflows that aren't going to ugliefy my tank. the top rim of the tank is about 2" from the wall and the stand is about 1.75" from the wall. thanks
