Pondering on adding a sump to my 32 biocube. Don’t wanna cut holes and am looking at maybe an overflow box in the middle chamber . Question is my water line in a bit low there and wonder is anyone else has done this . Will a box like the eshopps 300 go deep enough on the inside? Wanting to add for cheato more volume etc . Lil better skimmer maybe . Anyone have one that they have done without cutting or drilling?
