I own a Fluval Evo 13.5 and have been looking into battery backup options for the Sicce Syncra 0.5 pump. Are the APC UPS 1000VA or 15000VA good options? (I am also considering the IceCap Backup V3, but some of the reviews make me wary.) I want something that will run the pump in my tank for at least a few hours if the power goes out. Thanks!
