Eshopps 7″ by 200 Micron Filter Bag
Filter socks stay hidden in the sump but offer significant benefits for clear aquarium water. These micron filter bags provide excellent mechanical filtration, reducing ammonia-producing organic matter. They also prevent larger items like sand, crabs, and snails from damaging pump motors.
Available in round or rectangular shapes. Rectangular bags offer 2x more filter space than round models, ideal for larger sumps or users who want to change filter socks less frequently.

The rectangular bag fits perfectly in my large sump. Water clarity has improved noticeably since I installed it. It’s easy to install and lasts longer than the previous filter socks I used.

I switched from round to rectangular and now have to change the filter less often. The 200 micron rating helps keep debris out without clogging the system.

Great product for maintaining clean water. The bag stays secure and doesn’t shift during operation. I noticed fewer snails and sand particles in the water after using it.
