Your test kit can lie - and in my CPO® certification class, I show you how. Watch excessive chlorine bleach out the DPD free chlorine test, making a heavily chlorinated sample look like it has little or no chlorine. Then watch chlorine react with phenol red, converting it to chlorophenol red - an indicator with a much lower pH testing range, roughly 4.8–6.6. At normal pool pH, that altered indicator turns brilliant purple. Like Barney exploded in a test vial. That color doesn’t mean your pH is through the roof. It means chlorine interference just hijacked your test. Knowing how to add drops is one thing. Understanding what those drops are telling you? That’s why we take the class at www.cpoclass.com #PoolTok #ScienceTok #PoolChemistry #CPOCertification #TalkingPools
