it has a 180 micron mesh and comes with a convenient resealable locking closure. so this works with the bottle of purigen you just bought...the other one is a bag with purigen inside it but "can't" opened to put new purigen in...you can always use pantyhose instead for a cheaper price..also look at dr foster and smith have bags too for cheap..I purchased a large container of Purigen and I have noticed that its way too small to fit in my standard nylon bag.
So I need some type of bag to put the purigen inside.
Is Seachem "The Bag" the same thing as Purigen(with bag) ?
1. Purigen - 100 mL | That Fish Place
2. Seachem The Bag - 180 Micron - 5 in. x 9 1/2 in.
Sorry that was supposed to say can't not can
