I have (I mean, my daughter has!) goldfish. The 3 year old (goldfish, not daughter!) is living in a 29 gallon tank but want to move him to a 55 gallon tank since he's already over 6". I was going to buy an AquaClear power filter (hanging) but I've heard they can have restarting problems after a power outage (which are frequent in my area). I've heard that canister filters don't generally have this problem so I was considering a Hagen Fluval 306. Is this a good choice or should I just go with the AquaClear and purchase a UPS? I currently have a DC
inverter and a couple of car batteries for extended outages but I have to be here to set it up. Thanks for your time.
