Jack's Magic JMMAGENTA032 1 Qt The Magenta Stuff Sequestrant Jacks Magic, Price/each

Had white calcium marks on my black bottom pool, and after using Jacks for a few months, they are largely gone. It is expensive in my view though.

Have only had it for a few weeks but seems to be working just fine so far.

This stuff is good to have if you own a pool.

Good product and a much better price than pool stores

Have been using this for a few years now to control staining. Works well but will always need to treat a rogue stain here or there.
