ALEGILarge Filter Media Bags,Aquarium Mesh Bags with Plastic Zipper,White Net Bags for Bio Balls, Ammonia Remover 17.8" by 13.5" (2pcs)

Liked: good quality, well made, well priced, holds so much media.Disliked: I have no complaints

Had a really strong odor. Hard to pinpoint exactly what it us but I disliked it. Almost like a chemical smell. Will not be using it in the fish tank.

I used the bag to hold small 1” diameter pieces of pumice in my aquarium sump filter as well as some additional plastic media. The bags work just fine for the job, and seem to be pretty decent quality. I would recommend this product.

I have a 48” fish tank and I used this bag to contain my base substrate. It was the right size and holes were perfect. The zips were plastic so it won’t rust.

Works just fine Even the zipper works really well.

big size to hold lots of media for my sump

These kept my powers and nice and tidy!

Zipper likely to fail but bag is okay for one to two seasons of use
