I just bought an ATI Bubblemaster 160.... and had a coralife for a while....
what a world of diffence, I was like *** when I saw the skimmate come out of the bubblemaster....
It skimmed so much more the coral life that I had that I wanted to say sorry to my corals and fish for all the waste that was still in the water prior to the ATI.
But like all things in this hobby... there are many products out there. Just make sure your purchase doesnt end up in the closet with all the other cheap stuff you may have bought...
Sometimes you do get what you pay for.... the trick is to pay for it only once...
lol, but to answer your question.... BubbleKing, ATI, OctoPro, Reeflo, ATB Conical, SWC Extreem, DAS , H&S... look in the equipment forums as there are many user reviews of these skimmers.
