UEETEK10 Aquarium Nylon Mesh Filter Media Bags with Zipper, Suitable for Aquarium Garden Pond (9.8×13.7 inches)

I bought these to use as laundry bags to wash my nylon watch straps. They work well. The zipper is somewhat crappy and they shrivel up a bit in the dryer, but they stay intact. At the low price for a 10-pack, they are nearly disposable.Useful in coolers to keep smaller items together. Handy, buy some.

Bags are way too big and far to porous to hold anything but large media (bio balls, ceramics, etc). Phosbond and Purigen sieve right out into the water. If you have a canister you are probably Ok but of you have a sump like me, forget it. It just makes a mess.

I should have paid attention to the size! Going to use in a aquaclear 110 and there about twice the size I need. Bottom appears to only be glued together so still waiting to see how long they last.

I’M VERY SATISFIED WITH MY PURCHASEITS VERY STURDY COMPARED TO MY OTHERS I’VE PURCHASED BEFORE FOR MY POWER FILTERS WHICH ARE AQUA CLEAR 110/500 POWER FILTERS

Not for Purigen!!!

I was very disappointed with how the charcoal powder went right through this "mesh". You could do better with pantyhose.

DON'T BUY, SEVERAL HAD NO ZIPPER TO OPEN OR CLOSE!!!!

These are huge - I would hate it but I have found a use for these bags - 3-D puzzles or other classroom toys that I can see through the mess.
