I'm settting up a 180 tank in my family room with a 180 sump in the basement which has about 13 feet head. I plan to have a dsb/algae refugium in the sump. I'm looking to buy a mag 3600 to pump about 1600 gph from the sump to tank. I currently have a mag 1800 pumping from sump to tank at about 650 gph and the noise is minimal. Does anybody have any idea what the noise will be with the 3600
(I'm concerned with vibrations, rattling, water turbulence etc.)
An alternative I was thinking would be to keep to mag 1800 doing the same job so the sump to tank turnover rate will be about 3-4x per hour and then put a tunze 6060 and a couple of other pumps in the tank to increase the turnover rate in the tank at about 10-12 times/hour.
Which is better? If anybody can provide any input with your experiences, it would be greatly appreciated.
