I have a 300 gallon Rubbermaid stock tank that I need to have heated to a temp of 70f. room temp is 66F.
I can't use the 425 watts of aquarium heaters i have, due to the electric company being crooks, thats a nother topic. I also cant raise the houses thermostat past 68f due to the same reason.
The stock tank is indoors and does currently have fish in it and those fish species list is in my tank setup details.
I have also used hot water stirred into the tank water but that hasn't done much.
Any suggestions that don't use electricity or my hot water heater?
And is really low cost?
