Adding Bleach w/CYA in skimmer?

[RknRusty]

Sorry, I shouldn't have posted info based on my assumptions.
I thought it may be a bad idea because my seal fouled at the time I was slow-pouring bleach into the skimmer. I usually add it to the water in my 24' round pool as it goes round and round, just ahead of the skimmer, and try to make the pour last one revolution of the water. I decided to give it a little blast one day and, SCREEEEEEEEEEEEEEEEE... Well, you know the sound.

It is NOT a good idea to add undiluted bleach to the skimmer of a pool equipped with an inline chlorinator. A bad reaction (e.g. explosion) can result even if the chlorinator doesn't contain any pucks but only residue.

Anyone suggesting that forum users add bleach to the skimmer should caveat that advice with this information.

Excellent point Kurk!

Chorine residue is nasty stuff. I dont even like opening my chlorinator to put in more pucks because of the gas that comes out.

Honestly I never thought of the interaction between the pucks and the liquid, but I always poured bleach around the perimeter anyway.

I'll stay clear of the pump-seal debate......
