    Soapy backwash water

    Doing a backwash today at an indoor pool, the water coming from the backwash line was soapy-like bubbly soapy. It was definitely soap because I filled a bucket with the backwash water and it was soapy...pool is hazy. ONly chemicals added ever are: sodium hypochlorite, acid magic, sodium bicarbonate and calcium chloride. No algaecides or any other products and no one added soap to the pool. But, there was a mysterious foam on top of the chlorine in the chlorine tank...

    thank you,
    126,000 indoor recreational pool with a retractable roof.

    Re: Soapy backwash water

    Any chance someone bought scented bleach by mistake?

    The foam in the chlorine tank is the puzzler. I've seen a huge pile of meringue-like scum on a pool caused by lotions and sunscreen (I called the health dept on 'em!) but I can't imagine why chlorine would look soapy unless something else was added.

    By the way, the active ingredient in acid magic is plain ol' Muriatic acid, which you can probably buy a lot cheaper.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
