Cost effective massive fish room?

[PartyHacks]

How can I create a cost effective fish room.. I live in illinois so temp goes to 0 and also to 102.

Would you control the room temperature instead of each tanks temperature?

How about filtration?

An air pump running sponge filters in each tank?

How could you do it cheaply and efficciently? Maybe 20 55 gallon tanks sized.

A single Alita linear piston airpump running sponges on all tanks and control room temp. Auto water changes with a water heater hooked up to thermostat, irrigation/sprinkler controller and carbon block for chlorine.

I lived in Wisconsin when I had about 20 tanks.
Half were for species from Uruguay that didn't require heaters, so in winter water temps in those tanks dipped fairly low.

I did not use traditional aerators, but instead would put 4 to 6 tanks on a single sump, with a water pump (that also added heat).
For the other 10 tanks that required heaters, combined with the cost of pumping water, my energy cost Dec thru March still averaged $400 per month, mostly because the fish house was not heavily insulated.
I plumbed the tanks so old water from water changes was sent directly to my gardens during warm season, and I considered the double use of water a savings.

I also rigged the room so when a toilet was flushed in the fish room, water to flush came from the tanks acting as a small random water change, and new water went to tanks, instead of down the drain.

Linear air pump to supply air lift with a battery backup for power outages. Multiple tanks on sumps as single systems. Basement where the temp is cooler in summer.

I maintain a fishroom in my finished garage and designed it to minimize energy use. I insulated the garage well and made sure that the door, garage doors, etc. gaps were closed well. I replaced the windows with dual pane ones. I also installed skylights to basically eliminate the need for using the overhead lights or individual lights. I heat the whole room with a split-unit HVAC system and use several fans to distribute the air well. I let the room get cool in the winter (lower to mid-60s) and warm in the summer (lower to mid-80s) to reflect seasons. I only use heaters on a couple of tanks. I use a single, central air pump to provide air to box, sponge and /or Poret filters... although I run a couple of supplementary air pumps for deep tanks and a few powerheads for "dump" filters for large tanks. The whole room is on a water change system (drip system + PVC overflows) that water my raised beds and lawn.

Fish that don't require heat, sunlight where possible or at the very least cheap weak LEDs, air powered mattenfilters and hornwort
Seasonal temperature changes will probably be fine for south south americans, us native fish, east asian fish, or european fish
