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!

This stuff works!

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.

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.

Best product to lower phosphates

Worked as advertised and cheaper then what you buy at a pool store.

About every 4 days I was having to brush greenish algae appearing on my in-ground pool's plaster walls. I had a water sample tested and it showed my Phosphates were high at 437 ppb, the ideal range is 0 to 100 ppb.I added this Orenda PR-10000 product at the end of the day so it could do its job overnight and I kept the filter pump running overnight. Wow! Next morning my water was ultra crystal clear - just amazing. Next day I took my water sample for testing and the Phosphate level measured ZERO!! I highly recommend this product for algae due to a high phosphate like I had. Haven't had to brush any algae since- very happy customer here.

For the first time in over 4 years I had multiple algae blooms in my above ground pool. I put the entire bottle into my pool and it immediately became cloudy. It took running my pump 3 days to clear and backwashed daily. The following week I added another bottle. Turned cloudy (not as much as the 1st dose). This time only took 2 days to clear. This is the only thing I have done differently than ever before and now use 50% less chlorine tablets weekly to keep my levels appropriate. Not sure if this is coincidence or if phosphorus affects chlorine consumption. Will definitely order again next season.
