I'd take one pump offline and connect a heater to the battery backup. You can buy a battery powered air pump at a fishing tackle store. Use that for water circulation and then you can plug in two heaters. Letting the heaters heat up as fast as possible will be slow enough. Good luck!

As many naturalists and environmentalists have suggested, we should set aside our arrogance,
our desire to conquer and control everything, and walk hand in hand with Mother Nature. -Walter Adey
