Pool Frog Chlorine Bac Pac by King Technology

POOL FROG Bac Pacs come pre-filled with chlorine and easily insert into the Mineral Reservoir dispensing low levels of chlorine for 1-3 weeks. With precise feeding, you will use up to 50% less chlorine compared to the minimum EPA recommended chlorine level of 1.0 ppm for a stabilized swimming pool. The handles on the Bac Pac are easy to remove and you will never have to touch messy chemicals again.
