Chlorine Shock vs Non-Chlorine Swimming Pool Shock

We all use sanitizer to keep our bodies of water safe. Chlorine is the most widely used form of sanitation.  It is available in granular, liquid, and tablet form. Some of us may manually add it while others have chemical feeders. There comes a time in every pool operator’s life when we need to shock, or oxidize, our pools and such.

We do a lot to take care of our swimming pools, spas, splash pads, water parks, and the like. Balancing the water is one of, if not THE most important aspects of this care.

We know how important accurate water testing is when taking care of the pools we operate. It keeps our water clear, our bathers safe, and keeps the health inspectors off of our behind! That is, of course, if we are keeping accurate logs. You may be using old-fashioned paper logs to log your findings. You may still be testing using reagents. But there is a better way.

A Guide to Pool Algae

I am not only a Certified Pool and Spa Operator, but a Certified Algae Prevention and Eradication Specialist. I went to www.cpoclass.com to get my certification and will be referencing the accommodating textbook, “How to Get Rid of and Prevent Swimming Pool Algae”. Both of these are by Rudy Stankowitz.

Pool Log Sheets

We all dislike having to log our swimming pool water test results for various reasons. It is time-consuming. Unfortunately, it is required by law. I am quite surprised to hear how many facilities are still using the old-fashioned technology of paper pool log sheets. These are old hat. They are inefficient, time-consuming and cumbersome. There are other ways.
