    Using Stain Free and Metal Free from Natural Chemistry

    I use Stain Free/Metal Free to rid my fiberglass pool of stains. It works great. How long should I run the filter after I use these products? Also, How long after adding the products can we swim?

    Thanks for your help!!

    You should run the pump for at least an hour after adding any chemical. For sequestrant, you can swim after five minutes.

    Thanks!! So, now my PH is 8.0. I added the muriatic acid. How long should we stay out of the pool due to the muriatic acid.

    retest the ph after an hour. Once it's in range you can swim.
