Algae (plural) are common in swimming pools that struggle with chlorine efficiency, sanitizer killing speed, and high phosphates. This article is an overview of what algae are, and how to kill and prevent algae from taking over your swimming pool.
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.
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?
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?
Phosphates in pool water have become a common problem, yet the topic is largely misunderstood or misrepresented. Do you know what phosphates are, where they come from, and why they cause issues for pool chemistry? If not, this article is for you.
