IMO I would just put the $150 or so dollars that you spend on the coralife skimmer and buy a good used skimmer. I ran a bakpak, seacrap-i mean seaclone, and a home made skimmer which I thought all of them worked well until I got my current one a Euroreef RS80. Its night and day difference in the skimmers, it'll skim like crazy (not now cause its dirty, but thats my fault). I got mine for a buck fifty off ebay, you can find something around that price. The guys on here know their skimmers.
just my 2 cents.
