Used to put coral in my tank. Works fine. Doesn't cinch all the way, so be careful which end you are picking up from.

I use my filter media bags to hold my crushed coral. They work great!

It's a filter bag... I got it for a diy gimmick, but it's not gonna work for my intended purpose... It seems to be quality though...! Keep up y'alls awesomeness...!

I purchased filters for my aquarium and I’m extremely pleased with them. I have also purchased many other items and I haven’t been disappointed as of yet. I love everything that I have purchased thus far and with continue buying from aquarium coop.

So I was placing an order and to add a little more to my order to make the shipping worth it I bought two of the large media bags for my Fx4. And based off of the dimensions I figured two would be needed for one tray that wasn't using the red bin due to maximizing space. And they do just what they're supposed to do I filled them both up halfway with what media I had and made them fit. In the future I would like to see a larger media bag for situations like this but right now I can't complain.

Just got it today and am pleased with it so far. The small size is a nice size but perhaps a little too big for my 20 gallon long, but it doesnt feel like its overcrowding. I paired this up with some crushed coral I bought here and it seems good so far.

It is long and narrow, which I did not expect. I use it to keep extra media on hand. Has good flow. Got bags from another place, and they had much finer mesh likely restricting flow.

I bought the pack of small bags to hold crushed coral in my tank. Two of them comfortably fit the 1 lb bag of Aquarium Co-Op crushed coral.

It's a great media bag for my filter!

Easy to use and fits my filter perfectly

its a pleasure buying aquarium products from knowledgeable people as opposed to petsmart ,petco etc..

responds to emails ?s very quickly and helpful

Good quality media bags. Just wish they came in a 4" by 6" size. They would be more versatile for HOB filters that way.

Nice bag with small holes.

Needed a bag for the crushed coral and this is the perfect no nonsense bag that was the perfect size.

Bag had small holes, zipper easily closed . Held up well . Good price

Love the size, and if you're worried about them coming loose just knot it.

This feels like it will last a long time. It has come in handy for getting activated carbon into a tank, holding ceramic filter media, and crushed coral.

Great quality

working great for aqua soils

Awesome products, quality, and knowledge

Co-Op filter media bags are easy to load and allow for ideal water flow. The high quality material, stitching, and thick drawstring allow for extended reuse and hold up to high flow.

Very easy to custom fit to my filters. It can be rinsed and reused a number of times, so it is economical. I definitely would recommend this product.

The bio rings I put in this haven't moved at all. I have had no issues so far!!

I used this bag to add crushed coral to my aquarium. Seems to be a good size for this purpose and well-made.

Enjoyed buying the products that they had. Price was reasonable. Only thing I noticed was the shipping. They could of put it in a Flat Rate USPS box and I would of had it in 4-5 days instead of almost 2 or more weeks. I enjoy the Videos on You Tube!! Marcia

Great quality very satisfied
