MarineLandCarbon Bag 12/4 CT (AQ-78235)

These are easy to use. I only wish they could open up wider as I had to use a small measuring spoon with a slanted end to be able to fill them with filter media. They are small so I will probably have to buy another bag set for my canister filter. Right now I have four in my marineland magniflow 220 canister filter. Only one bag will fit jammed into my pen plax 600 cascade(polishing)internal filter. Very very messy to use(fill the bags outside)but will save you a significant amount of money if you buy these bags and a big jar of filter media and fill it yourself versus expensive pre made media.

These are the perfect size and are super-fine mesh to use for catappa leaves to make "teabags" for my betta and African dwarf frog tanks. They give you the tannins while keeping the messy, broken down leaves inside.I also use a these for filter media bags on my smaller hob filters for my 5.5 gal tanks.

The description says its more of a 1 size fits all. I have a marineland 360. these were TINY. Would fit a HOB filter but if you have a canister like mine youll need 2 packages.

Large enough mouth to easily pour media into. Fine mesh and could be used for carbon if needed. Easy to use over all.

I love these little bags, they hold the perfect amount of carbon for my reef tank. They are well made and easy to close.

Misleading listing- these are way smaller than expected. Looking back, there’s really no indication of size in the listing other than the misleading picture. The only dimensions listed are package dimensions which aren’t accurate. Furthermore, the size box these are packaged in is borderline absurdly too big for the bags that are in it. Overall 3 stars because these will work and seem to be good quality for a good price, but I’ll need to use 2 in place of 1 in each section of my fluval 306- good thing it’s a 4-pack!

Very small but worth every penny just dump and reload 🤣😂😍🤭

I use these as a filter sock over a 1” foot valve so my irrigation pump doesn’t get ruined by debris. So far they work great. Sometimes if debris get too clogged then it needs to be wiped clean, but it beats having to buy a new pump.

Very handy small bags that hold very fine resins or other media. Only down size is the rapid increase in price of these. Gone from $8.00 to $12.00 in less than a year. Seems steep.
