Pro Prism Skimmer
 

I've found a pro prism skimmer for sale for $100. Can anyone provide feedback? (are they good skimmers? is $100 a good price?) I'm not sure what the exact model # is - hopefully pro prism skimmer is enough detail.

i had one for a few years, its less than wonderfull, but for a smaller tank needing a hang on skimmer it will do a ok job once broken in. but you will have to fiddle with it all the time.
i would try to find a used one,ive seen them for $50-60 in the sellers section and thats all they are really worth.
