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

Finally, Something That Actually Works!I’m seriously impressed with the Orenda PR-10,000. I had been using a product called " FhosFree" before, and it did absolutely nothing for my pool. I was skeptical about spending more on this, but wow—what a difference! This stuff removed phosphates on contact, just like it claims. The water is noticeably clearer, and maintenance has been easier since using it. It’s definitely professional-grade and worth every penny. Highly recommended if you're tired of wasting time and money on products that don’t deliver!

This stuff is the best for getting rid of yellow algae. It’s not a one and done but it does work quickly after treatment. I bought the big bottle to make sure I have enough for the whole summer

Keeps my pool crystal clear. I live in an agricultural area. This time of year with all the nut harvesting my pool collects lots of very fine dirt. You can’t see it, but it’s there. I will double dose during this time. I’ve used other products but this is the one that does the job. You will see it as soon as you throw it in the water…it clouds up as it attaches to all the phosphates/organic matter. I run my pump for 24 hours then backwash ( I have a sand filter system) for 4 minutes, rinse, purge all the air out of my lines, and reset on my regular maintenance cycle. During the winter months I use this once a month. I’ve not had any problems with algae since using this. Highly recommend.

Phosphate is very bad for pools because it feeds algae and no one likes swimming in algae. This product is extremely effective at removing it. Read and follow the directions and you’ll love the results. Be aware- as this product works over a few days your water may become very cloudy. You’ll need to be patient and also need to run filters continuously to clear it up (then back flush or clean your cartridge filters once pool water is clear or pressure goes too high).

I’ve maintained my pool for 23 years. My area of Pennsylvania has extreamly high phosphates strength out of the hose. 1500 plus. I tested and treated my pool for 1500 ppm with PR-10000. First time I have ever had a zero reading on phosphates. My chlorine level shot up to 3 ppm from .25. I’ve used many brands and this is the best. I contacted orenda and they say I can use a maintenance dose of 1oz per 10,000 gallons of pool water a week. That’s what I used with other products. It barely clouds the pool. This is the holy grail of phosphate remover. For me I put in the dose when I can monitor the filter pressure. When it rises 10 psi I recharge it. I had to do it 2 times. The first rise came quick…. Like 3 hours after adding. The second rise was days and I just checked morning and night. Now my summer will go smooth.

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.

I had phosphates 187 on Friday for my salt water pool and I received my jug late Sunday and pumps were abiut to turn off so I poured 2 oz mixed with pool water around the pool as per instructions (11k gallons) on Monday at 9am and on Tuesday at 11am tested pool water and it registered 13 woo hoo. I wasn't expecting it to fully circulate until 2 full days. I am a believer in this product. Have tried others and this concentrate is far better and much more effective. Don't bother trying other brands this is the way to go. Look how sparkling it is. Look how clear it is.

Size, value and quality are good worked well and ease to use. Just follow instructions
