So my latest question is are there any battery backups that are useful for freshwater tanks. I would need to plu in a 200 watt heater and 2 filters. I have seen lots of backups for marine powerheads and such but no advice for freshwater. I know it will take a while for the tank to lose heat so I'm nit as concerned about that, but I don't want to burn up a filter motor by having it kick off then on again without being primed. Any thoughts??
