I have the Seachem Tidal 55 filter in my 30-gallon tank. I have Purigen and Matrix Carbon in two of Seachem’s “The Bag”, each in its own bag. Well, I want to replace “The Bag” with something different. “The Bag” is too big and the material it’s made of is too stiff for my liking. I can’t get it to fit in the filter basket the right way. You close it with a zip tie which adds to the bulkiness. I just don’t like it. Can anyone recommend a fine Mesh 180 Micron Filter Media Bag to replace it with?
