DIY protein skimmer

[Tipton34]

I built a protein skimmer, set it up, and it never created a layer of foam. Is this because i was using water out of the bath tub to test it or is it a design flaw? All ideas are appreciated

Skimmers usually dont foam in fw... I tested out my new skimmer in a bucket and it did the same thing, just filled up with white cloudy water, no foam

Yea they don't work in freshwater. Some claim they do but I've never tryed one.

This is a decent article that explains the basics of protein skimming and even differentiates several models.
