Tunze question

[Ehaze]

Im looking into getting a tunze stream for my 75 gal reef aquarium. i was wondering what would be the best economical/flow choice? do controllers also controll the speed? I was thinking of something in the flow range of 2000 to 3000 tops gph. Im interested in both models with and without controlls.

You could go with 2 6055 and a 7095 or 7096, or 2 6105 if you have alot of SPS and need more flow. For non controllable pumps you could use a few 6045 or a couple 6065 (SPS). The controllable pumps are speed controlled, so yes, you can control the speed, the non controllable ones cannot be speed controlled and won't work on wavemakers, they should only be turned off every 15 minutes at most.
