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

Best price you'll find. Works better than pool store brands

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.

This stuff is amazing. If you have trouble holding your chlorine level, then you probably have a high phospate level. When you add it, it will turn the pool cloudy white. And the whiter the pool, the worse your phosphate problem was. After 24 hours, you will need to wash the filter, brush the sides of the pool, wait another 24 hours and clean the filter again. Works every 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.

I've been struggling with allergy in my pool for about 15 years. I spoke to somebody who told me that my pool may have excessive phosphates. I read the reviews on this product and it was all great so I bought it. I used it and for the first time in 15 years I don't have allergy bloom in my pool. I still get a little bits of it but it's only like 10% of what it was. The only thing is that you have to clean the pool filter first and if you use a lot of this it will start to plug the pool filter back up again because it's attaching to all the phosphates in the pool making them a solid so the filter can catch them and keep them. It's great and I highly recommend this if you have ALG issues

This products really works well, preventing from algae growth in my pool.

While 'Phosphate Remover X' is a little bit more cost effective than this (albeit hard to find), I still consider this among the best phosphate removers on the market. Certainly a great deal better value and more effective than the overpriced 'weekly dose' garbage you get from the pool store.
