Orenda PR-10000 Removes Phosphates On Contact, Pool and Spa Phosphate Remover Concentrate, 1/2 Pint

I’ve tried several phosphate removers for my pool, but Orenda PR-10000 is by far the most effective. It works on contact, and I could see the results almost immediately. The water became clearer, and my phosphate levels dropped significantly after just one use.Pros:• Fast-acting – noticeable results within hours.• Highly concentrated – a little goes a long way.• Keeps algae under control – by reducing phosphates, it prevents algae growth.• Easy to use – just pour and let it do its job.Final Thoughts:This product is a game-changer for pool maintenance. It does exactly what it claims and saves me from dealing with algae problems. Highly recommend for anyone looking to keep their pool crystal clear with minimal effort. Will definitely be purchasing again!

Did great. 16k gallon pool used the whole container and dropped phosphates from about 900 to 300. Didn’t even cloud up the pool. Would buy again.

I used the 8 ounce bottle on my 10,000 gallon pool and it immediately went to work. Turned my pool milky white. Make you shock your pool the day before and brush. I spent the next 3 days cleaning the filter each day and vacuuming the bottom. Pool looks amazing and algae issues seem to be resolved. Be patient, it works!

I had purchased so many things to kill the phosphate in my pool. I have no trees in my yard but all my neighbors do and blow all the debris from their trees when they trim them. It kills my pool every year. But it was particularly harsh this year. With storms and wind. I put this in my pool and it cleared it up so fast. I would definitely recommend this if you’re having issues with phosphate. The only thing I have an issue with is that they raised the price this product $10 in less than a month. And no, it wasn’t on any kind of sale when I purchased it the first time. But it works really well.

As a new pool owner (no pool cage - open air, 12,500 gallons, in-ground pool located in SW Florida), we were constantly chasing our lower chlorine levels. All other readings appeared to be in balance. A local pool company tested our phosphate at 1000 ppb. After reading reviews for Orenda products (and learning a great deal on their website and their Calculator), we then realized how our landscaping could be impacting our phosphate levels.After receiving the PR-10000, we conducted their website's "Red Cap Test" where we poured one capfull of PR-10000 into the pool and checked the size of the cloud spread in the water (Cloud size = Basketball size = need to address phosphate). Our cloud spread was the size of a large beach ball.We dispensed only 4oz (recommended dosage based on all factors using their online Calculator) around the perimeter of our pool. 24 hours later, our phosphate level was down to 200. While I haven't tried other phosphate removers, we're very happy how ~$7.50 of product (January 2025 pricing) lowered our phosphate levels from 1000ppb to 200ppb. We anticipate we'll always have mid-higher phosphate levels based on our climate, vegetation, fertilizer, etc. So we also anticipate having Orenda PR-10000 on hand when needed.Thank you Orenda for your excellent product, website tools, and the learning materials you provide to pool owners.

Worked really good but didn’t realize like size bottle was more for an above ground pool so it took the whole bottle for our In ground pool

Easy solution to moderate phosphate levels.....added 4 of ounces to 10000 gl. pool, ran pump for 48 hours, and cleaned the filters.... definitely lowered phosphate levels.....

I guess it did what it advertised, but honestly I couldn't tell any difference between this and my regular algaecide. They both killed the stuff in the pool and it settled to the bottom.
