Review on 🐠 Optimized Baby Brine Shrimp Net & Copepod Sieve for Artemia Brine Shrimp Hatchery by Rebecca Smith

The mesh appears to be around 100 microns (0.1mm) and is held firmly, albeit with some permanent creases, in the plastic rim. The black wire that goes to the buttons is fine too. The plastic handles on the ends of these wires fall off almost immediately (I don't think they were glued in any way), and a few of them crumbled (the plastic fell apart) when they were first picked up. So I use these little filters without handles and so far they are fine. Things like rotifers go straight through, but there's brine shrimp and copepods.
