I have a 7500 fiberglass pool, used the entire bottle mixed in a bucket and poured into pool, it only made two small white spots in the deep end, depleted my chlorine and sent my other chemicals off the chart !?

Hi Richard,
Sorry to hear you’re not getting good results with it. It’s typical of most stain removers to work on the bottom of the pool more in the deep end first. You can open a support ticket and we can diagnose what’s going on with it, send you what you may need for free to get the stains off, and/or send you a refund. You can open a ticket here: https://help.unitedchemical.com/portal/en/newticket

Had large green stains in the deep end of the 23000 gal. vinyl inground pool from organic material from the winter. Tried scrubbing to no avail. Over chlorinating, thinking chlorine would do the trick. Was at wits end until I spoke with the United Chemical Tech (Rick). He proposed I look into United Chemicals Pool Stain Treat Spotting Bag. Followed directions and within a couple of minutes the stains had dissolved completely. I am now a happy camper. Thanks Rick!

I have a 25000 gal pool and I used 2 bottles of your Pool Stain Treat and I mixed into a bucket of water and spread it out throughout the sides of the pool and after 24 hrs of continuous filtering I see no difference in the stains at all.
