what is the best way to protect my fish when the power goes out? all the ups systems and ecotech battery back ups i have been investigating do not seem to do everything i need. i want to have my tanks on life support for at least 48 hours without issues. all together i am using about 2200 watts. I already have the ecotech battery back up for my return pump, but it only runs the pump at 20% or something. last week the cleaning lady tripped the breaker and i lost 3 fish in 7 hours. totally unacceptable.
