What my experience has taught me:
- Put in floor drains if you don't want water drainage pipes crossing walkway aisles. If your unsure where your racks will go, add in extra as they can be capped or cemented over.
- Use a dedicated electrical circuit for airpumps only. Nothing else uses this circuit so it can't get tripped. It's also easier to backup powee for one circuit. I use Medo linear piston pumps. Two pumps per central air circuit for redundancy as its cheaper and neater than having 2 sponges per tank. I try to have the same model airpump everywhere so it's easy to swap out and keep spare parts as well as a spare pump.
- use high ceilings if possible. You can rack 5 tiers high if expansion occurs. Additional storage is always good. The main cost is floor area. Room heating is similar.
- I use one overflow drain per tank and waterchange by displacement. Much simpler, cheaper and reliable than a drain & fill system.
- put your steel stand legs on 15mm HDPE blocks to keep them high and dry. Water sits under the steel for weeks otherwise.
- put in an oversized water line if you need to fill big tanks. Could put a tap at each end if you don't like long hoses everywhere.
- place your main aisle in front of the door with branching aisles to tanks perpendicular off this. You will need to wheel in tanks, tubs, fish boxes etc so plan door size and access accordingly. The dead ends are perfect for nets, food, equipment shelves.
Just my suggestions.
Appreciate it. Good points.
I need to add floor drains. They are not in the current plan because the contractor does not like them (says they clog eventually). But PVC drains crossing aisles would not be ideal.
I'm stuck on ceiling height. I think I am at 8.5' because of the way the walls sit on the brick foundation. So its a little taller than normal.
