Its cloudiness indicator confirms active performance, simplifying pool maintenance while effectively preventing algae growth. Trusted by professionals and homeowners alike, it delivers powerful results with minimal dosing and hassle. ## Description PR-10,000 is a highly concentrated rare-earth phosphate remover. It is formulated to react with phosphates in the water, allowing them to be removed from solution. It reacts with all known types of phosphates on contact and hardens them into a fine precipitate, which falls out of solution. The inert phosphates then floc out, to be vacuumed or filtered out of the pool.

I have a 20K gallon pool and we do get a good bit of dust (I live in Arizona) that has a tendency to jack up the phosphates in my pool. I have seen other comments but have to say this is a way better product and value than PhosFree. Has reduced my phosphates about 75%, down to an acceptable level. No issues with the filter or pump. Review: This works. - This stuff is great. I manage a 185k gallon private "public" pool that is seasonal, so we can't afford to have any kind of substantial closure since the season is relatively short. Over time, phosphates build up due to it being an outdoor pool and heavy bathing load. The local pool store offers free water analysis, and suggests their own-branded solutions. For our level of phosphates (2500+) they wanted around $1400 for the amount of chemical to treat it. Fortunately we had some PR10000 from a prior year, so I looked into it and started using some as a trial. The "old" (~1 yr) PR10000 didn't work as well but clouded immediately. I could dose it gradually over the span of 7-10 days to keep turbidity down (and the pool open). After dosing around 3/4 gallon of the PR10000 we retested and the phosphates dropped by roughly 1000ppb to ~ 1600ppb. We are continuing to dose the PR10000 and will dose it occasionally just as a routine PM chemical. The only issue with this, beyond the cost, is that old PR10000 doesn't seem to be as effective as new stock, so I hesitate to order larger quantities that I might not use this season. Other notes - we've also had issues with increased chlorine consumption the past several weeks (2-3x) which for our pool is on the order of $1000/wk in increased chlorine alone. We'll see if bringing phosphates down addresses that. We also had a bout of black algae in various spots that we've never had before. Apparently this is a common issue with high phosphates. Again, will see if lowering phosphate level gets that in control. ## Features - Highly concentrated, removes phosphates on contact - PR-10,000 causes cloudiness indicating performance, which can last anywhere from a few hours to a few days - Reacts upon addition in water, circulation or filtration is required - Use as needed, and do not exceed the recommended dosage unless otherwise specified - NSF/ANSI-50 Certified for Professional Use ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B007BSRVQK | | Best Sellers Rank | #2,877 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #12 in Swimming Pool Clarifiers & Enzymes | | Brand | Orenda Technologies | | Brand Name | Orenda Technologies | | Customer Reviews | 4.7 out of 5 stars 2,156 Reviews | | Item Form | Liquid | | Item Type Name | Swimming Pool Chemical | | Item Weight | 3 pounds | | Manufacturer | Orenda Technologies | | Manufacturer Part Number | ORE-50-226 | | Model Number | ORE-50-226 | | Number of Items | 1 | | Package Size Name | 1 Quart | | Product Benefits | Removes Phosphates from Water | | UPC | 898880001305 | | Unit Count | 32 Fluid Ounces | ## Product Details - **Brand:** Orenda Technologies - **Item Form:** Liquid - **Item Weight:** 3 Pounds - **Product Benefits:** Removes Phosphates from Water - **UPC:** 898880001305 ## Images ![Orenda PR-10000-QT.

I'm not an exact measurement guy. No visible algae? 1/4 bottle followed by few ounces 2-3 each week for "maintenance". LOVE this stuff.... When you pour in, the water where you poured will get cloudy, don't panic. You will also need to vacuum really well 2-3 days post adding the initial treatment. Watch your water start to "sparkle"..... **Q: Can I use this in a 350 gallon hot tub?** A: You should be able to, just have to leave the pump running longer. It start to kill on contact and takes about 30-45 mins before you can get in the water. **Q: Do you have to vac the entire pool after puttin this in?** A: No vac needed This product is well worth the money I'm on my second year on my bottle. Algicide is a waste of money this stuff works and very concentrated **Q: Is this nsf safe? (the half pint size indicates nsf safe - is the quart size also?)** A: Yes, it’s safe ## Customer Reviews ### ⭐⭐⭐⭐⭐ Product works well and is a better value than other alternatives *by B***T on May 1, 2026* This stuff has worked phenomenally well for me.

Algae eats phosphates so, if you can get rid of your phosphates, you have solved your problem. Last year, I had a phosphate level of over 2500 PPM and the only solution that I could find was a product called Phos-Free from Leslie's. It was expensive and it required that you clean your filter before application to the pool, then let the filter run for 48 straight hours, and then clean the filter AGAIN, which was a giant hassle to say the least, as I have a cartridge filter that takes 45 minutes to clean in the blazing sun. This got my phosphates down to around 800 PPM, which somewhat mitigated the problem without completely solving it. (Note: I really like Leslie's and appreciate that they have a store near me with water testing and I will continue to buy all of my other chemicals and tabs from them, which are great.) I just didn't want to deal with the Phos-Free process this year and tried Orenda out of laziness/desperation. It really works like magic. I poured 4 ounces in my 16,000 gallon pool and the water immediately clouded and stayed that way for an hour or so. I use it in conjunction with Leslie's Perfect weekly now. I have poured in 4 ounces three times so far this summer. My last phosphate level was 85 PPM. No black algae.
