Any pool workers out there? level of disinfectant in pool...
Former Member
I'm wondering when is the chlorine at the highest level in the pool during a typical day. I read somewhere that usually you add chlorine at night, and add acid in the morning. What's the implication of this? Does it mean chlorine level is highest in the morning? What about ozone? Any pool workers (current or past) can shed some light? Thanks :)

I am not a professional. But I know that chlorine breaks down in sunlight. The effectiveness of chlorine varies with the Ph of the water. Depending on the local water characteristics they may or may not add acid. Some pools will instead add soda ash to raise the Ph instead of acid to lower it.
Depending on how chlorine is administered (tablets, liquid, etc.) the chlorine level may vary radically. Not intentionally - but because of human sloppiness or environmental conditions. For example if the pool has a chlorinator and they forget to turn it down at night the pool often will have high chlorine levels in the morning. The level will drop quickly if it is an outdoor pool and the sun is out.
