For you engineers here, is there a formula I can use to determine what size heater I would need to raise water temps in my indoor RAS tank? BTU's needed? Water temps stays in the mid 60's (it's in the basement), but I may want to raise it about 10 degrees for faster fish growth and more optimum biofilter performance -- if it's economically feasible.

The water in this circular stock tank is 324 gallons.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
