I am planning a basement remodel that will include bar with a 90 gallon reef tank as the focal point. The bar will be built along one of the below grade concrete basement walls. Since this is the early design stage, I would like to get it right from the start. I would like all the plumbing to include sump, protein filter, etc. to be in the cabinet below the tank and if necessary I can plumb from the tank to a utility room that will be off to the right side of the tank and bar unit. I plan to build a custom cabinet for the tank and sump. One issue is because of the concrete wall, there will be no access to the back of the tank. Any help on design concerns, equipment, etc. would be appreciated. Should I forget about plumbing everything below the tank, instead have everything run the utility room and return back to the tank? I plan to have a RO/DI reverse osmosis installed in the utility room that will be eight-feet away from the tank. I have not purchased any equipment yet so I am open to suggestions?
