I nearly pulled the trigger on a clearance fiji cube sump that had a filter roller built in for $180 on BRS. I just didn't have time to take on emptying the tank and cutting out the acrylic wall then plumbing in an overflow. Would have been sweet though. Sump is Def better than this slimline aio section.The skimmer clip worked like a charm, but I'd come home from work and the water level would be totally different. I wouldn't know if it was saltwater that had been added or if the ato dumped a bunch of freshwater. Such a pain, I'm not sure if a sump would've been easier or not lol.
