i got a sweet deal on a eshopps sump and id love to be able to use it with my biocube without drilling it or destroying the lid. i plan to upgrade in the next year or so and id like to be able to use it as an AIO in another room. with that said has anyone found a HOB overflow box that would fit with minimal modification im thinking an Eshopps nano. im just not sure if that flow rate is gonna be high enough (about 200gph) and if it will fit. thanks guys i appreciate any advice im just determined not to drill the tank.
