Rotifer Sieve - 40 Micron Sieve - by Bubblemac Industries, Inc.

These work for sifting rotifers and small fish. Also any tiny particles you want to sift out of liquid. Buy two you will find a use for more then one. I did.

Works absolutely as it should without fouling your breeding tank with whatever 'fry' you are raising.

Works well, just as I expected.

Works like a charm. We use this for our fish facility.
