Loose filter media like bio balls or ceramic rings scattered directly in a canister or sump makes cleaning and swapping media a mess. Dymax Filter Media Bags keep everything contained and organized, in coarse, fine, and extra fine mesh grades across three sizes.
Why Bag Your Media
Loose media mixed together in a compartment is slow to clean, hard to sort by type, and prone to migrating where you don't want it. A mesh bag keeps each grade of media separate and makes swapping or rinsing media during maintenance dramatically faster.
Choosing a Mesh Grade
- Coarse — for larger media like bio balls or ceramic rings that don't need a tight weave.
- Fine — for finer media like activated carbon or fine ceramic pieces that would escape a coarse bag.
- Extra Fine — for the finest media, like polishing pads or very fine carbon dust, that escapes even a standard fine mesh bag.
Choosing a Size
Each mesh grade comes in Small, Medium, and Large sizes to fit different compartment dimensions across canister filters and sumps.
