2380 Swimming Pool Metal-Stain Control, 16-Ounce

This is amazing. I added this to my pool when my copper levels were high. The copper levels were drastically reduced as a result. We vacuumed out black specks afterwards where the chemical had bonded to the copper in the pool leaving it easy to clean up. I also cleaned my pool filter cartridges after treating the pool with this. I would certainly use this again to reduce metal in my pool water.

Works great. First time I filled my new hot tub the water turned the color of Mountain Dew after a few days. After adding this product my water cleared up. I use it everytime I fill tub or add water.

this is for a spa not a pool.

Thank you

Does the job! This is a must if you are on well water or a public supply that uses well water

recommended by the spa manufacturer, works great

Great!

It seemed to work OK, how do you really tell?
