I would have kept the tank if it wasn't so scratched on the glass. Sent from pay phone in the airport. said:Lol. Lies!
I would use a Mag pump...they are solid and my 55 ran on one for years. said:and add a lot of heat, that is why I moved away from mag pumps. Eheim is good solid pumps, I have switched to a Jebao DC , even less heat than Eheim and adjustable flow.
I owned a DAS tank once, removed the internal "useless" filter and ran a over box , never again. For the effort your about to do I'd find a good used RR tank.
