1-Quart 4-Pack Concentrated Metal Out, Pool Metal Remover | Pool Stain and Mineral Inhibitor, Stain Remover, Easy to Use, Works Fast, 1 quart per 10,000 gallons of water, Made in USA

Works as it was intended

If you have bad water with lots of iron, you need to keep this stuff handy. I replaced my pool liner this spring and to save money filled it with the hose from my house. My water is very rusty, and I knew I would need something. So, I bought metal out and used it as directed. Needless to say, it worked wonderful!!! Pool filled, water was ugly, started filter and a day later pool was almost crystal clear. Couple of filter backwashes and a good vacuuming and the pool looks great. I will be supplementing with Metal Out every time I use the hose to top off my pool. Must have if you have rusty water.

I put 5 oz in and it went from purple to pink on test strip I just put 5 oz more to try to get to orange. This is after 5 oz. It was purple it's not even on the strip but turned my hair green from solar ionizer. It's affordable and works!!! Just lower your chlorine to nothing and pH

I was very hesitant to use this in our pool but it worked good with also doing other iron removal methods. We have hard well water so the iron in the water made it very dirty looking even though it wasn’t. Adding the metal out and doing the sock method (check out YouTube for that) our pool was clear after a week. The first two photos are 5 days apart and the third is what it cleared ended up looking like after a few more days. We do not have new water running through our pool constantly so we only needed to use one bottle of the metal out. I do not think that using just the metal out would’ve been effective, the sock method was a big help in getting all of the iron out.

Great for the pool. Makes it really clear.

Helps keep metal stains out of pool. We have well water.

I have staining that appeared on my pool liner this year, but this treatment did absolutely nothing for me. It's possible my issue just wasn't appropriate for this stain remover, but it was a swing and a miss trying this chemical to remove light brown stains from my pool liner. Absolutely no improvement at all.

This kept my pool clear all summer. It went from orange to blue clear in just a day

Don't fallow instruction about waiting for chlorine to be gone from pool , just put it in !!
