I have been happy with my coralife 65 (on a 29 gal
tank). Although, take that with a grain of salt as I have not used other skimmers. I do recall a thread on Reef Central where they compared the coralife 220 to a remora pro and the conclusion seemed to be the coralife performed better--is this consensus; I don't know.
As for the price question, check out www.bigalsonline.com
. They have the 220 on sale for $142.
