skimmer recommendations for micro reef?

Hi ... I have a 20g microreef in the office, and would
like to ge a protein skimmer for it. I used the Prizm
in the past, and was not happy with it (it started
leaking, not a good thing for a tank in the office!).

The tank has been doing OK for about a year without it,
but there is a coat of darkish algae on the live rock
which is kinda annoying and hard to remove. Also the
coralline algae isn't growing well.

Any recommendations for a protein skimmer? I don't
have a sump so it would have to be a hang-on or small
internal. I've read negative reviews of the new Fisson
nano skimmer. Anyone tried the Tunze nano protein
skimmer? Other recommendations?

thanks,
shireen
