Hi Christy
In the past everyone thought that we needed to push our total flow through our sumps. This has changed drastically with the use of Tunze, Vortex and closed loops.
The Reef Ready tanks have only provided for a flow of about 1500G per hour.
I believe that the things t consider now on a reef return pump are: Output
Heat
Noise
Electrical consumption
Purchase price
Dependability
Maintenance
There may be more.
I am using an AMP Master 3600. It delivers about 3000G per hour. Which allows me to run both tanks and a number of other devices with still enough flow through the sump to maintain my skimming and heating requirements. The Amp Master is absolutely silent and has zero heat transfer. It is one of the lowest power consuming pumps on the market at approx 90 watts per hour. The majority of Sequence ReeFlo pumps are rated at 150 to 200 watts per hour. The Dolphin Amp Master pumps are a little harder to find now as the Sequence ReeFlo pumps have replaced them in the market place. I hope this helps and if you need more help then call.
