Powerhead Flow And Number Needed For 120 Gal Dt

[sahmof2]

I have just upgraded from a 55 gal to a 120 gal DT. What size and how many Koralias are recommended for a 120 gal DT with 150 lbs of liverock in center. I want to keep mushrooms polyps and SPS corals. I currently have two perculas, royal garama and damsel. Will be adding a regal tang later.

Thanks,
Sahmof2

With appx 250 lts and a turn over of 20 times per hour you will be looking for a combination of power heads to produce a final figure of 5000 lts an hour..depending on how many you want in there combine at least two korallias to give you this hourly total turn over, or even slightly over it..this flow rate will be perfect for any of the species of coral you have listed
