Do you have any pictures??Did this back in 2013. Had several things in the planning. DT is 430 gallons. This faces into in the great room. Hybrid in-wall install. Tank is 3 feet wide. Two feet are visible outside the fish room so I can see from end to end. One foot extends into fish room. Tank sits on square metal tubing stand, so plenty of room below tank for equipment. Put extra rebar in the foundation to help with the weight of tank and water. Fish room is a 2x4 level lower than the rest of foundation just in case some major water spill would not flood the house. House is on septic so fish room drain goes into a dry sump not tied into septic tank. Put 3" PVC pipe in foundation that goes to outside of the house. Put flex PVC through this pipe so I can get salt water with my pickup truck and pump directly into a 165 gallon holding tank via 12 volt bilge pump. All the other usual stuff. Sink. QT tanks, etc.
