    Need recomendation for stain preventative

    Need recommendation for stain preventative type/brand at start-up for a new re-plaster. 14000 ig, colored quartz sand plaster, re-plaster to be done next tuesday march 18. I presume the plasterer will tell me what to use but I want to educate myself as much as possible.

    thanks,

    Brian`

    What kind of stain are you trying to prevent? Do you know that you have metals in your water?

    If you do not have metals, then you just need to maintain adequate chlorine. If you do have metals, then you will need to use a sequestrant: http://www.troublefreepool.com/conte...d-metal-stains

    Re: Need recomendation for stain preventative

    I'm inquiring regarding new re-plaster directions which say "add stain preventative"once the pool is filled. The link below has the water info(scroll to bottom) on my municipal water that I will be filling the pool with.

    What do think?

    thanks,

    None of those numbers show up for me in the link ... plus didn't you already test and find that your water is different?

    You only need stain prevention if you have a source of stains (like metal in the water). If you want to be safe, then add one of the sequestrants listed in the link I previously provided.

    Brian,

    The link you gave shows that the iron level is not detectable in the surface water and is in the range of ND-280 (so 0.28 ppm max) with an average of 42 ppb (0.042 ppm) in groundwater. However, groundwater is only 7.6% of the city's water supply making the iron amount negligible. Copper had 0.26 ppm in the 90% percentile but that includes copper leeching from indoor plumbing. Manganese was at extremely low levels (in surface water and low levels in groundwater).

    So it looks to me like you don't have a metals problem in your water supply and your use of a metal sequestrant is not necessary.

    Plaster is in, pool filling.

    "So it looks to me like you don't have a metals problem in your water supply and your use of a metal sequestrant is not necessary."


    PB agrees, none is necessary.

    Thanks to all for your input,

    Brian
