sharkypoolpro Posted August 24, 2011 Report Share Posted August 24, 2011 i have one of my commercial pools in the same neighborhood as a few others and it seems to grow algae like its a petri dish. the only way to rid it (i have tried everything!!!) is superchlorination (last time i used 25 lbs calhypo and its a 36k gal pool with a 9' deep end) for about 24 hours, then a quart of floc for 2 hours, then pump off for 24 hours, then vac to waste. i didn't even let my chlorine level come down past 8ppm and still within 4 days it started to bloom again. i am putting a lot of chemical and a very lot of time into this mystery. just yesterday i put 8 cups cal hypo, then 1 qt silvertrine, then at the end of the day 1 qt floc. i have like an inch of dead algae that i need to go vac up now. what can i do to keep this growth down?
