Your cart is empty.Jack's Magic The Magenta Stuff is a great choice for any pool, preventing and removing ugly metal staining and scale buildup. Its powerful liquid formula is a sequestering agent that binds together any dissolved metals and calcium that can cause problems, allowing you pool filter to quickly remove them. It is highly effective at controlling plaster dust during pool start-ups, and is compatible with all sanitizer systems, including saltwater systems. In fact, using The Magenta Stuff will actually help extend the life of saltwater pool's chlorine generators by keeping scale at bay. Best of all, this product features Phos-Stop Plus, a unique additive that not only adds no extra phosphates to your pool, but actually lowers the amount already in the pool, preventing algae growth. Product Dosage Initial Dose: 32 fl oz per 15,000 gallons of water. Maintenance Dose: 6 to 8 fl oz per 15,000 gallons of water per week.

Didn't work for me. The pool company recommended this, but I still have stains.

We had yellowing along our pool steps and in a corner. It was not the yellow algae that is often found in pools. Treatment with this worked well to remove the coloring quickly and easily.

Just wish this stuff wasn't so expensive. It seems our local pool store is constantly out, so good that I can order it on Amazon.
