MarananthaPools

I have been cleaning pools for three years in Southern California. I have used this product before and I like it. I used it as directed-test phosphates- add recommended dosage pool turns cloudy-retest next week add some more if needed and then clean filter. Someone that I buy chemicals from said add a capfull every week to my pools. Has anyone done this? Does it not load up the filter? Any feed back appreciated. Josh
