BioGuard Pool Magnet Plus, 1 Quart, Concentrated Formula, Metal Stain Preventer, Works Quickly & Easy to Apply Effective Pool Maintenance

I'm amazed! My steps and pool were turning brown from iron. The white you see on my steps is from the bottle of Stain Free Iron Remover, which was good, but would have taken me several bottles because it wasn't clearing the whole pool, but this Pool Magnet Plus was the real star! I was worried about putting this in with the pump off, but overnight, it's crystal clear! I do plan on following up in 24 hours with Sparkle Up to clean the iron from my sand filter. This is a pricey product, but WORTH IT!

I have spent hundreds of dollars testing out just about every method to get rid of stains. Just a bit of a "past" tense of the issue. I started off the season with a nasty algae attack on my pool in the beginning of the season... Like a nub (dummy) I threw WAY to much algicide at it. (STAY AWAY FROM COPPER BASED! At least cheap algicides!) I also had my pool deck pressure washed. I am pretty sure they used some sort of chemical that had bleach and some other stuff in it... So I not only had the algicide, but some other unknowns... Because of this my metal levels in the pool sky rocketed... MY pool was crystal clear and then when I got my chlorine levels up BAM... Hello coffee looking pool linear... Two bottles of this and the stain is gone! Now for me I did try a few other products some of which cost $40 a bottle... Don't ask... BioGuard works a bit slower but when you spread it around the pool and do what the bottle says... After a couple of days its as though the stain is completely gone. Further - Last year I also had metal issue but it was because of my faucet has hard water. Highly recommend you keep up with the metal count in your pool. Even getting on a program to keep metal out "just in case..." Understanding the variables that happen to the pool are extremely important. This way you can diagnose and eliminate the issue. This product works wonderfully. The price, the speed, the value is right on the mark. You will need to use another product such as a filter aid to help eliminate metals entirely as this will mostly help with the stain itself.

AMAZING stuff. I thought it was expensive, but it worked right away and after using it, it is worth the money.

Package was slightly damaged upon receipt.

This is from applying to the stairs, and not scrubbing over about 20 minutes. If you’ve got iron buildup on your plastic parts, this stuff is amazing. One bottle is enough to treat the entire set of stairs and skimmer box.

It is good the product does the job

Easy to use and cleared our steps in a short period of time

It did help but it didn't completly remove the copper stains from the liner
