    Rant about dollar store bleach

    I was on my way back from work and knew I needed chlorine for my pool, so I stopped at Family dollar store to buy some bleach. It's the easiest to stop at place by a long shot for me. I've had good results with their bleach before. 6% meant around 5.2. So I bought the last two gallons on the shelf of it to make up the 48 oz I would need. Got home. Tested the water. Added what I figured. Waited an hour. Tested again. Came up with same amount. Tried testing again, but same. Not having any distilled water, I just mixed half of the bleach and half of pool water and tested. Came out almost zero. Tested with 10ml of straight "bleach"... ZERO. Pink with the powder? No. Nothing! Be warned! Lucky I had some cal hypo tabs and my calcium is low enough. I bought bleach a week ago from them with good results. Now their bleach is nothing more than water and NaH. Sure raised my pH. They may have ran out and found some in the back that's old as me.

    All bleach bottles have a date code on them. I'd bet that if you look at those, you will find it was very old.

    Sorry that happened to you. That is a good lesson to us all to check the date codes.

    Since you used the FAS-DPD to test the bleach it'll bleach out at that concentration. I'd use the OTO test to see if there's any chlorine in it. It'll get nasty looking, but it won't bleach out.

    That is the downside to the FAS-DPD test. It can give a false 0. Anytime you get a 0 reading on it, always verify with the OTO test.

    Re: Rant about dollar store bleach

    It can give a false zero, but the FC has to be much higher than anything we recommend before that happens. I've purposefully mixed a solution of over 100ppm FC and it read it accurately. It's really not a concern unless you've added an extreme amount of FC.

    I do agree with Steve about double checking any zero reading with the OTO.
