how old's the tank? The guys on the nano-reefer forum don't bother with skimmers on tanks up to 50 gallons. The cost of doing frequent water changes is tiny on a small tank, and is usually just as effective. some of those guys do twice-a-week changes of 15% each and have absolutely stunning sps tanks.
The tank's only 33 gallons, and a remora's for something round 66 gallons. I think it's a waste of money because of the price curve. spending $180 for 33g of water, compared to $300 for 120g of water on a larger system. Except for cycling liverock. would make cycling live rock less smelly and significant others less whiney
