Phosphates. The invisible common denominator behind many pool problems, elevated chlorine demand, and sometimes even cloudy water. Removing phosphates is the third of Orenda's Four Pillars of Proactive Pool Care. This third pillar is an easy one to master. The action step is simple: keep your water's phosphate levels as low as possible; ideally below 500 parts per billion (ppb). In this article, we will explain why phosphate removal is so beneficial and important, even if it's not always mandatory.

Once again, wildfires rage with devastating fury. To say they are a disruption would be an understatement. We sincerely hope your homes and communities are safe. But even if you are not in eyesight of the flames or smoke, there is a good chance swimming pools will be affected in the region. A good rule of thumb is if you can smell it, it is impacting your swimming pool. Debris can travel many miles, and smoke can travel hundreds of miles. Even if a home is not touched by the flames, there is likely to be a recovery and clean-up process once the flames are finally snuffed out.
High phosphates seem to weaken chlorine, as evidenced by low chlorine readings, lowered ORP, and the most visual of all evidence: algae. What’s really going on?
What kinds of phosphates might be in a swimming pool? There are several variations, and this article will outline some of them. Mainly, we want to illustrate that some phosphate compounds will not show up on an orthophosphate test kit.
When a pool turns green it could be for a few reasons. But if it's green from algae, there is a proven clean-up procedure pool pros can use. Green pools, after all, are not uncommon. But if you have ever tested for phosphates in a green pool, chances are the levels were very low, if not zero. How is that even possible?
