Ratings & Reviews
Does not work well
Rated for 300 microns yet 150 microns pour out of it
Approx. 300 micron
I purchased the bags to hold my de-nitrating resins. and purgen. My advice is don't. About 30% of the resins went through the bag. I later purchased Magnavore's Pura Media Bags. They worked with nothing leaking out. The lesson learned is appox means close to but not quite. Other than that its a good bag for other media. But not anything asking for 300 micron.
Just the right size. Perfect for my canister, just refill with carbon and go.
