What is the most quiet return pumps?

[JPotter]

I am interested in this thread as I have recently set up a 120gal sps tank and the noise from the return drives me nuts!! I have the sump in a closet..the sump is on styrofoam and the pump is submersed and on neoprene. When the return is off the other pumps in the sump are hardly noticeable.

I don't want to go with minimal flow..would rather too much than too little. Are these Red Dragon pumps seriously quiet? What size would be preferable for a 120 gal tank.

Thx

Hey guys,

Havent i seen your cards at JL?

Anyway, i'm using a reeflo dart right now, and its pretty quiet, considering its in a cabinet. Im happy with it. BUT, make sure there are absolutely no elbows on the intake line of the reeflo if you want it to be as quiet as possible, because they are extremely sensitive to negative pressure (restriction on intake side).

Red dragon is good too, if you have $$$$$ One thing though, keep in mind that the red dragon pumps are uncomparable to reeflo when it comes to pump size-watt draw-flow. I looked into buying an equivalent red dragon pump to the reeflo dart, and it was a huge pump, and was going to run me approx. $1000.

My advice: go reeflo. I mean, poseidon is great, but it heats your water, and wont get as much pressure. You can ask Jeff at JL; awhile ago, both of the titanium shafts on their poseidons rusted out, leaching harmful metals into their tank, killing most of their nice sps corals.......
