Jacks Magic Salt Solution The Purple Stuff For Swimming Pools - 1 Quart

This stuff works great! I opened my pool and there were stain lines. I filled my pool and poured the solution into my pool and it worked it's magic. Stains gone! I add well water to my salt pool and I know this causes stains too. Magic Jack's works well!

My pole looks fantastic. Crystal clear.

I add this to the pool once or twice a year. It almost instantly removes stains.

The Purple Stuff does work as the directions say on the bottle

I use this product every year for our pool.

Required pool maintenance.....seems to work

When used with other Jacks Magic products it works as expected to remove pool stains.

Had only minor discoloration from the iron in our well water. Our sand filter (with Zeosand) along with the Jacks and a CuLator removed all color in a day. Don't know how much the Jacks helped. The price is quite high as is the price of the Culator. I have not shocked the pool yet and had to add a lot of chlorine in to raise the level to 2ppm, so much so that I thought the chlorine might be bad, however, apparently the iron consumed much of the liquid chlorine.

Great product

It didn't work and is so expensive I will never try it again!
