Hi,
Its been a while, but fall is fast approaching and my reef is needing some required attention. I have a Mag 7 that I am using as an in-sump return pump in my 50 gallon reef. I would like to replace the Mag 7 due to the noise. The pump is reaching the end of its life as the internal impeller can sway back and forth due to wear. This is with a new impeller so its the motor unit. What pump recommendations do you guys have for replacing this Mag 7. My limitation to flow rate is that I have a 1/2" Sea Swirl which can handle flow rates up to 550gph. I have about a 4 foot rise in pipe with 1 right angle and 2 45 degree fittings. Thank you for your suggestions...........................Jim
