    Stamped concrete dust turned pool dark brown

    I just had my stamped concrete patio around my new pool installed. They had left all the colored dust all over it and we got a terrible rain storm. My pool is now dark down. I have doubled up on skimmer socks, running filter 24/7. Using my pool robot with 2 micron filter bags 2x a day. Does anyone have any other suggestions? My sparkling water is gone....

    Has it stained the liner? You can try turning off the pump overnight and letting the dust settle on the bottom and then slowly vacuum to waste.

    The dust they use for stamping contains metals - up to 60% iron oxides in some cases - as well as (depending on recipe): copper, manganese, cobalt, chromium and many others.

    Get that stuff outta there ASAP!

    The old pros here can lead you to the "how". Make sure you get the stamping sealed to prevent anymore stuff from washing into the pool.
