Frank and Jac discuss how one of their technicians did not treat a group of about 20 pools for one or two weeks. With rain and rising temperatures, this was a recipe for the biggest green-to-clean week since they've been in business. And all one week before Memorial Day.

Frank talks about his favorite 3 methods of turning neglected green pools back to blue and swimmable. His version of the Bob Lowry method, the Orenda method, and the Alum method.

00:00-05:40 introduction

05:40 new tech goes rogue

11:20 how to turn a neglected pool back around

11:40 Three processes we use, Bob Lowry process, Orenda process, Alum method

12:40 what to do regardless of method. remove debris, start with a clean filter,

13:18 Orenda method. lower pH to 7.2, chlorine 10 to 15 ppm, purge dose PR10000 (according to label), circulate pool for 10 minutes, pump off for 24 hours. Day 2 vacuum pool to waste. net any remaining debris, if chlorine is 3-8 ppm, phosphates below 500 ppb, turn pump on for 24/7 until clear. Add purge dose of CV600 enzymes. adjust lsi, check and balance over next few days.

17:19 Bob Lowry method. balance LSI with pH 7.2 to 7.4, add non-stabilized chlorine to achieve 40% of cya level, maintain levels for 24 hours, test and brush 2 times per day. if after first day if algae is not gone, take chlorine to 60% of cya level. watch filter pressures backwash or clean as needed. add purge dose of enzymes

20:25 Alum method. adjust pH 7.0 to 7.2 , alkalinity 100 to 120, brush well. water temperature needs to be 70 to 90 degrees. . dose 8 to 9 lbs of alum per 10,000 gallons. remove cartridges from filter or de grid assembly from filter, or if a multiport valve run in recirculate, do not run alum through the filter. If cannot bypass filter media use sump pump or trash pump to recirculate. recirculate for two hours, turn system off and let it sit for up to 24 hours. then vacuum to waste. removes algae, phosphates, and lowers stabilizer levelsl

26:15 recap, post cleaning, and follow ups. watch filter pressures, clean or backwash as necessary. balance lsi, maintain chlorine levels after at 7.5% of stabilizer level if not on borates, 5% if using borates.
