MasterLine ZipBag, 12 x 17cm (1 ml)

The purity filter medium stays where it should be: Very fine 250-micron material and high-quality seams prevent the purity granules from escaping - the risk of damage to aquarium technology etc. is minimal. The practical zipper is made entirely of plastic so that the bag can withstand 100 percent chlorine and acids.

This filter medium bag was specially developed for the MasterLine Purity product, but can also be used with similar filter media.

Note: The capacity of the large bag (L) is approx. 500ml, that of the small bag (S) is approx. 250ml.
