I used a garden pump sprayer, while the filter was running, to spread it evenly over the surface of our salt water pool. We had so much phosphate the pool stayed cloudy for almost 3 days after application. Now the pool stays clear, no algae and it’s easier to keep the proper chlorine level. Use this once a year and your pool will be great. Review: Good product. Works as stared. Worked so well, it lowered my pressure on D.E. filter. Disassembled filter and cleaned it. Pressure back to normal. Next up vacuum pool Price is debatable for only a quart.I am satisfied with product performance ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B007BSRVQK | | Item Dimensions LxWxH | 15.2 x 25.4 x 55.9 Centimeters | | Item Weight | 1 kg 360 g | | Item model number | ORE-50-226 | | Product Dimensions | 15.24 x 25.4 x 55.88 cm; 1.36 kg | ## Product Details - **Brand:** Orenda Technologies - **Item Form:** Liquid - **Item Weight:** 1.36 kg - **UPC:** 898880001305 ## Images ![PR-10000-QT Phosphate Remover Concentrate, 1-Quart - Image 1](https://m.media-amazon.com/images/I/21k2F8NZllL.jpg) ![PR-10000-QT Phosphate Remover Concentrate, 1-Quart - Image 2](https://m.media-amazon.com/images/I/311hpV2IwoL.jpg) ![PR-10000-QT Phosphate Remover Concentrate, 1-Quart - Image 3](https://m.media-amazon.com/images/I/31REeIib0eL.jpg) ![PR-10000-QT Phosphate Remover Concentrate, 1-Quart - Image 4](https://m.media-amazon.com/images/I/41piRzLFCML.jpg) ![PR-10000-QT Phosphate Remover Concentrate, 1-Quart - Image 5](https://m.media-amazon.com/images/I/71sb841jqsL.jpg) ## Questions & Answers **Q: How much should I add for 25,000 gal inground pool?** A: Depends: algae issues? 1/3 bottle . 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 ### ⭐⭐⭐⭐⭐ Review *by D***7 on 19 August 2025* Best phosphate remover I’ve ever used.

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.
