    What size ups for back up power?

    Don, I have tried 3 brands of pumps so far on the xantrex, all have run without problems. Tunze, Maxijet, and Rio. For my application, an Acrylic 25g nano, the xantrex seems to fit the bill. However when I get the 300g I have been dreaming of....... -Bret

    What size ups for back up power?

    Does anyone have experience using a UPS for back up power? they all quote 20 min, but would it last longer if I only ran my pump (8 watts) and 50 watt back up heater? If so which ones work well? I would like to plan for a 4-8 hour outage. Thanks, Bret:confused:
