You're there...overkill that is. IMO, don't waste your money for a skimmer for a 10 gallon nano tank. You'd be better served using the money to buy the salt for the water changes you use for the weekly water changes. Anyway, SeaClones get thumbs down in most posts/reviews I've read.
Honestly, I bought an AquaC Remora for my 24G. The few times I've used it, it only pulled out about a cup of green tea looking water and not foul smelling either. It didn't look anything like that horrible 'oily, foul smelling' stuff others claim they pull out. But then again, I do my weekly WC's. IMO, save your money if it's a ten. SH
