Found this article, a bit long but I'm curious as to TFP's take on it.

Is Superchlorinating The Best Way To Eliminate Chloramines?

Chlorine is a great sanitizer for pools. It's been the backbone of our effort to keep pool water clean, and will remain so for the foreseeable future. But a controversy has emerged in recent years about the process of superchlorinating — what we call "shocking" — pools to reduce the buildup of...

I've no opinion one way or the other.

Thanks,

First off, I am so thankful TFP does not have advertisments and use popups.
SLAM Process SLAM is the process. Shock is a one time event and not recommended for TFP pools.

Agreed, thanks. It struck me that they (well, DuPont) kept hammering on the dangers of over-chloronation.

In my view it's not an issue for the TFP method because the FC levels are kept high enough in relation to CYA that regular shocking is not required.
Now, if you follow the industry standard of 1-3ppm FC, regardless of CYA, then algae is bound to appear and when shocked CCs will be formed.

It's quite similar way of thinking to the pharmaceutical industry, they are more interested in treating the symptoms then addressing the root cause.

If they really are concerned about overchlorination, then they should stop spreading this widespread piece of misinformation that to get rid of chloramines, you have to add 10x the amount in chloramines worth of FC. This is wrong. The 10x rule applies to getting rid of ammonia (measured as ppm Nitrogen).

For the same financial reasons too. !

Thanks for correcting that on the 10X rule! Was not aware of that as being for ammonia.

No worries! If you are interested in the chemical background, than have a look at this post from from ChemGeek:

Is the formula for "Superchlorination" or "Shock" too high?

Is anyone trying the new formula for shocking (breakpoint chlorination) that Taylor and DuPont are suggesting in this article? Seems that the latest (2009) research suggests that the formula we've been using to determine the shock level of FC is really too high and itself contributes to the...
