Doheny's Extra-Strength Metal Out Pool Treatment | Professional-Grade. Highly Concentrated Formula | Reduces Staining. Scaling & Discoloration | Dosage View Stripe | 40 Oz. Bottle

We always have copper and iron boarder line on our pool test.. so I add 1/2 of the bottle 16-20 ounces to my pool first thing in the morning every month beginning or end of month during swim season.. I will clean my tank usually 3-5 days later. Not that hard when u have 2 swapping filters.. easy!

As directed, I used metal out in my pool when testing showed it was getting too high. Tested again a week later, and my rating was .1, which is normal.

Sequesters metals quickly at normal pH, arrives quickly, competitive price. Second year using this. Works well

Much cheaper to buy ahead of the season and stock up

Works well and good price.

great product, prompt delivery, great price

Thank you product works great

Love and trust this brand

Helps me get metals out from well water makeup.

Bought this as it said it was same as pool magnet in their book. It's a quart 1/4 size bottle. I bought 4 cause it's a better deal. I used a single quart of pool magnet a several weeks before and it did great. Tried one and nothing happened. Tried. Mother do 2 1/2 quarts worth and still nothing happened. Called them and it's a real headache to get much done about it and I have 2 more and have to buy other stuff now on top of this.
