where to add bleach?

[KirstenHW]

Sadly I cannot comment at all on the chemistry equations - I worked for my B in eleventh grade Regents chem all those years ago. However, I am now nervous as I have on occasion poured the bleach around the entire perimeter of the pool with the pump running - especially at opening. I have an 24 gal 18x42 vinyl ig with a 3 ft shallow end. Of late I have been adding the bleach to one of the 2 skimmers (one closest to non-cartridge DE filter). I add 1.46 gallon jug over the course of about 1-2 minutes time.

I won't do the perimeter thing any more - but was that really bad to have done?

KirstenHW, bleach mixes very quickly with the water when you add it. I think a lot of people add bleach the way you are describing it and it isn't a problem. It's probably better to add it in front of a return, but I'd doubt you've hurt anything by just dumping it in.

chem geek, I appreciate all the math and stoichiometry you present in your posts. It has really helped demystify the chemical processes going on in my pool. (And a big shout out to Evan for the same thing.) I suspect this thread may be getting near the China Shop Event Horizon given Ben's desire to keep from scaring people with too much information in the general forum.

Wow! Thanks for all of the replies. I was basically concerned with bleaching my liner (I have an AG Pool) if I poured it in front of the returns. Sounds like the general consensus is that I will be fine either way. Thanks again!

Yup, that's right.
