Hi all, I'm highly interested in getting a fleece roller for my AIO 24g. My question is: is the body watertight? Does the whole thing need to be submerged? Could I potentially have the media basket and bottom like, 1/4 to 1/3rd submerged and the rest sticking out of the sump compartment? I know it requires plumbing so I figured I can have the hose going to a pump that sits in the sump directly, ideally the first compartment in the back. If not the reefmat, any other suggestions? I currently don't have any sort of fleece Filtration going and I think it's contributing to a dinoflagellate issue I'm having.
