The filter sock fits perfectly in my sump system. The 250 micron mesh catches fine debris without clogging. It’s been used for over three months and still performs well. The plastic collar keeps it in place and prevents it from shifting during water flow.

I installed this sock in my overflow setup and noticed a significant reduction in floating particles. The mesh is strong and doesn’t tear even after heavy use. It’s a simple but effective upgrade to my filtration system.

Great quality and easy to install. The polyester mesh holds up well under constant water flow. I’ve used it in both a freshwater and saltwater tank and it performs consistently. The plastic collar adds stability and keeps the sock secure.
