Hey thanks! being only 13.5" tall I think that may just work!The innovative marine nano skimmer is the smallest skimmer i know of. They use them in there 16 gallon nuvo.
Would probably work in an 8 also.

Just going to add my 2 cents...I researched for my upcoming project a 10 gallon tank and was actually surprised to be told that if I am doing weekly 10-20% WC (water changes) then a skimmer would be a waste of money that would be better spent on nice coral frags. Dunno if I am being advised correctly or not but if I am and you have an 8 gallon would be same for you.
That's probably true if the tank has an extremely low bioload meaning no fish. Nano tanks with only corals can get by with water changes only and no filtration. It's a trade-off though. The cost of a skimmer for such a small tank isn't much, and you have to weigh that against the cost of salt (minimal) and the added labor for more frequent water changes.
