AQUANEAT10pcs Aquarium Filter Media Bags, Fish Tank Coarse Mesh Bags, 3”x8”/5.5”x8” with Plastic Zipper for Activated Carbon

These are great. I've filled them with aquarium soil and am using them under my sand and other substrates.

Zipper barely open 1in. So any material nearly impossible to put in.. says fine yet purigen and similar products goes right through. Waste of product, waste of money on these.Products literally just come right out of mesh all over tank, all of everything. Garbage

Though I wish I had bought the smaller size, these are great! I mix good quality charcoal with ammo carb and put about 3/4 of a cup in each bag. I store the filled bags in a zip lock and rinse prior to installing in filter. Highly practical product!

A perfect way to keep the canister medium cost efficient. Saves a lot of money. Fits perfectly in my Penn plax canister filter. Can use multiple mediums and I'm able to replace medium in stages and don't have to throw the entire filter out at once. Recommend.

Prices great zippers all look greatWow this Thank you seller it’s amazing I got these for that price I don’t raise your prices today until it’s all my kids they all have Aquariums

I am using them for the cotton filter, but the charcoal comes out so I have to use a different bag with smaller holes for charcoal.

I am using these to hold bio media in my sumps and they work fine. I like the zipper much more than the drawstrings most bags have.

Simple and easy to use. Zipper much better than drawstrings. Excellent for making Mosquito Bits tea to control fungus fleas.
