I have an opportunity to get my hands on a brand new protein skimmer for next to nothing at all. I was wondering if they are useful in a fresh water aquarium or basically just for marine set ups.
thanks

From my understanding, they simply will not with with fresh water.

I'd get it in case you would ever want to check out the "dark side." I doubt they would work with fresh water, becuase the protein solids sink in that type of tank. In salt, they float. The brown foam that you sometimes see when you go to the beach at the ocean is an example of the protein that these skimmers remove.

I've always heard they won't work in freshwater. I gave mine away. If it's free, why don't you get it, hook it up and see what it does?

Not needed, and they don't work efficiently. Has to do with the difference in surface tension of salt vs fresh water. They're better suited for salt tanks where water changes aren't done as often. In fresh water tanks, better to just do the water changes.

thanks for the detailed response. if it wont be effective than I wont use it.
If it is a "good" skimmer, there are tons of reefkeepers that will pay good money to take it off your hands..
