B-stock – Great for cleaning, final cleaning and winter storage, also for cleaning at the start and end of the season, as well as when heavily soiled.

500g PureFlow B-stock in various dimensions (offcuts) is ideal for heavily contaminated water, e.g. for initial cleaning at the start of the season or for final cleaning after the bathing season.

Use the cost-effective B-stock for coarse dirt in the pool, pond, stream or even for your cistern and then start a new, crystal-clear bathing season with PureFlow POOL 3D filter elements.

The B-stock is ideal for protecting your high-quality filter material from heavy contamination and thus extends its service life.
