Orenda PR-10000-GAL Phosphate Remover Concentrate, 1-Gallon

My go to fix for high phosphate levels in my pool. While the process is a bit labor heavy if the levels are high (the pool filters have to be cleaned each application after a 48-hour continuous pump running) if one stays on top of the phosphate level it becomes maintenance and not a rescue situation. My level was at 400-500 and it took me at least three applications to get it to near zero. But I've been able to keep the level in the 100 - 200 range for over a year if not two and no algae. 40x18 ft, 25,000 gallon pool in Phoenix, AZ.

This stuff works. It’s the only thing that gets my phosphates down to manageable levels. 1st app went from 4000 to 2200. Next app got it to 1300. Was able to get it to 900. Still working on getting it to passing level. Pool chemicals work much better even with phosphates around 1000. It’s a pain to vacuum to waste when it settles but it’s the only thing that has worked for me. Plenty of videos on line for whatever your situation is.

This is exceptional at removing phosphates from your pool! I always research what is in everything I put in my pool but the msds sheet on this says it’s proprietary so no list of what’s in it. What I do know is it works exceptionally I use it twice a year, before swim season and after swim season one week before I clean my filters. I can run out of free chlorine in my pool and not have issues with algae when I use this.

Excellent product, did wonders for my pool!

cleared up the algae after one time

This Orenda PR-10000 is fantastic. It stopped the black algae in my pool. In the spring when our trees are blooming and dropping seeds in the pool like mad, my chlorine generator on the salt water pool failed for a few days before I realized it, so no chlorine. The pool was loaded with phosphates, and developed a bad case of black algae all over the place. Small spots all over smaller than a dime each. I couldn’t get rid of it. I used other methods also like steel bristle brushes, chlorine tablets rubbed on, etc, but nothing worked until I got rid of the phospates. YouTube to the rescue! I learned that algae lives on eating phosphates as food, discovered this and bought a gallon. The “red cap test” showed that there was a lot of phospates. (Very cool test to do also.) I treated the pool two or three times and got them to basically zero. Then as another YouTuber suggested, I QUADRUPLE shocked it overnight with HTH Shock. The next morning almost no sign of the algae, just a few spots left and not dark black. I test phosphates now, and with this, they are gone! Thanks Orenda PR-10000 ! This product works differently than the other types that coat the filter. This precipitates the phosphates out of the water, they fall to the floor like in a “snow globe”. Very cool to watch in action.

This was a replacement order. The first showed up upside down and leaking. Don't know if the UPS driver was upset that it leaked in his truck or what. But when we picked up the box it was soaked and about half the gallon was missing. At least this shipment was in a plastic bag in the box. There was still a little leakage, maybe an once or so. But anyways, it works great, it's pricey bit not when you figure the cost against phosfree. My pool is 28,000 gallons and had a reading of 675 on the phosphates. The recommend dose is 6oz, with phosfree it was 3 liters. Plus the phosfree clogs up the filters fast. Found the best way to put it in the pool is to put it in a 1 qt spray bottle and go around the pool and spray . You don't dump it in the strainer. We get a lot of wind and dust here in Southern Nevada so it is a constant battle on phosphates. But a gallon jug usually lasts about 18 months. I recommend this product, just wish they would tape the lid down so it doesn't leak.

We have been used this product a full season last year, Mar. to Nov. I can't express how happy we are with how it fixed our green pool, something we fought with a whole season before. We are new to having so many trees around our pool area which increases our phosphate levels, alot :) We found with our 22k gallon pool, this will clear it up within 12 hours with 3 back washes... Now the fight is over...thank you Orenda...
