We left Las Vegas on Wednesday and drove down to Riverside into 100 degree temperatures (yikes! a record temp for Riverside in November!) for our CPO class this past Thursday and Friday, November 4-5. The drive took longer than we thought, so we couldn’t complete the set up until the first class day on Thursday morning. Elise was running around like a crazy person trying to get everything ready while students were arriving (and that’s NOT the way she likes things to go), but it worked out.
This class was our largest so far in Riverside with 17 students! (which is why we had to retrieve our narrow classroom tables from San Diego, so there was room for everyone!).
We had an assortment of students: old timers in the industry, newbies to the industry–in both commercial and residential areas. Very good questions were asked, information shared, and positive feedback expressed about the excellent class curriculum and the benefits of becoming CPO certified for anyone associated with pools and spas. (We definitely concur on THAT point!)
A CPO always knows the limitations of their test kit; for example:
♦ The DPD type colorimetric test to check free available chlorine will bleach out at high chlorine levels.
♦ Phenol Red will turn to a purple color at high chlorine levels. This could be mistaken as a high pH when the actual pH is below 7.0
We also discussed the importance of taking care of your test kit, the shelf life of the reagents and the accuracy and limitations of all the other testing the Certified Pool Operator must perform.
Our thanks go to PoolCorp and to Riverside’s Manager, E. J. Wamsley and, especially, to Kyle Maddox, Riverside’s Operations Manager, who has come in on Saturdays to lock up after us (with last year’s classes), has carried down our classroom materials, and volunteered to standby for us as we tried to close down the classroom setting in a timely fashion at 5:00 p.m. each day — Thanks a bunch, Kyle!
