Pool Shocking

I'd like to thank you for all the info, guides on how to videos and all your effort for all the above. Also i have to let you know that your books are very thought plant and informative for the beginner pool owner (i just got your books about a week ago). So on one of your videos you were talking about the cc been more than 0.6 ppm for three consecutive days on the YMCA pool that you were operating you had to shock it. My question is how could you shock it if it was operated every day and you had 5000 occupants every week.


I'm asking because i just recently start working for a swim school and all the training i had from them was how to hook up the vacuum hose and back wash, so all the rest of the little knowledge that i have about pool chemistry is from researching your work on the internet. I would really appreciate if you could help me out and if you have any advice for me on building up my career us a pool operator.




Thanks for the question and compliment. Concerning the shocking part, the Y closed at 5pm on Saturday. I'd be in there at 4:30 to get everything ready. I'd then shock the pool using enough calcium hypochlorite to increase the FC to 15ppm. Commercial pools have a 250 - 280 GPM (gallons per minute) so a turn-over of the water was relatively short, about 6 - 7 hours. I'd go back to the pool around 7am on Sunday and use a product called Thiosulfate, in granular form. It's the same Thiosulfate used in the TA reading on the K-2006 kit. That's in liquid form. Thio is a strong chlorine neutralizer and should only be used in special circumstances such as I used it. I had to quickly get the FC down to an acceptable level because I didn't have days to wait. The Y opened at 1pm.

Concerning the pool operations, honestly, anyone can backwash, sweep, and vacuum. The real trick is understanding the chemistry part. What I've found is most training that pool operators have severely falls short and does more harm than good. My understanding is much of it is directly or indirectly financed by parties that have a financial interest in the use of chemicals. One commercial pool operator who was on the Y board kept the CH on his pools at around 600 - 800ppm. He said it decreased the CC in the water and lessened the amount of shocking. I've not seen any viable proof of this, it seems it's just what he heard so he's more than happy to give the calcium chloride company more money. His pool and his budget.

If you need a CPO license then get it, but remember, they teach you book knowledge but you can always adjust when you start out. My supervisor really hesitated in allowing the pH to go over 7.4 because that's what he was told and was taught in his CPO class. Suits would bleach out and swimmer's eyes would burn. He couldn't put 2+2 together and realize that the local water company was already running the pH between 7.8 - 8.2. They were dumping huge amounts of soda ash into the water system, yet, there wasn't a line outside the ER at the hospital, nobody's skin was peeling off, no grass was being killed, no cars were rusting out, and nobody's teeth were falling out due to the pH of the tap water being 8.0. Much of it is not being brave enough to questions of what's considered "normal" and really digging in.

There's much information in the eBooks and I'm glad you got them. They cut through the bad information and gets to the truth. I can say without reservation that they're the best eBooks on the internet concerning pool water maintenance with much video proof to back it up. I can't fake taking a black/green pool and within 4 days have it clear and perfectly balanced for about $30. Other pool owners who have used my methods have sent me their video testimonies with before and after pictures.

About a career as a pool operator, I wish you the best of luck. And, if you want, I also do personal consults via phone or SKYPE. It goes much faster and more ground can be covered compared to email. Entire books have been written about pool operations and careers in pool maintenance. Going through everything in email form is time prohibitive at this point.

If you're interested in a consult you can go to this link and because you've purchased the eBooks you get a discount rate of $27:

When To Shock
by: Joe in Palm Coast, FL

I have used Pinch-a-penny for years....they recommend shocking once a week. You recommend when the cc is 0.6....what should I do? (I did get the 2006 kit you recommended).....and it coincided with Pinch-a-Penney's reading....my pool is perfect now....thanks to you.




I'm also in FL and well aware of PAP. I've dealt with pool store employees in 3 different states. Watch the video below:



We need to define what shocking is and why you would do it. Shocking is the process of increasing the FC high enough and long enough to kill the organic matter. That's where the CC comes into play. This is the reading you'll use to determine whether or not to shock the pool, not because it's Saturday.

I'm not referring to clearing up a pool. This is for weekly pool maintenance assuming everything is in line. A normal pool with a FC level of 2 - 4ppm will have enough power to kill 99% of organic matter. There are exceptions such as heavy use, tons of rain, large amounts of organics going into the pool, etc...

Maintain a FC level consistent with the right CYA and pH and your pool will stay clear.
