Thread: Newly replastered black pool

  1. Back To Top    #1

    Newly replastered black pool

    Filled pool and started balancing five days ago. Last night checked pH (6.9--pool contractor recommended keeping it low to offset new plaster impact on pH) and chlorine at 2. This morning woke up to a totally milky white, cloudy pool, with white powder noticeable on the first step (couldn't see below first step). I drew a cross in the powder with my finger, and it was so fine it dissipated like smoke.

    I have been brushing the pool since Monday but with little residue noticeable, until now.

    My question is: 1) is the cloudiness due to the new plaster and 2) how best to eliminate the cloudiness. I have Sparkle up to add to the sand filter, or should I use a flocculant and vacuum?

    Thanks for your comments.

    Here is the Pool School Article on How to Start-up New Plaster.

    What specific instructions did your contractor give to you?

    It would be helpful if you added your pool and equipment specs in your sig.
    Go to User Control Panel (top left under TFP logo), select Profile, then Edit Sig.

    Plaster dust is fairly common when you do a standard startup. Make sure you keep the PH under control, keep brushing, run the pump all the time, keep the filter clean as needed, and the filter should catch up eventually.

    I haven't figured out how to attach pictures yet. I already tried and only seem to have an image option, not an attachment option.

    I have my camera set on the 640x480 pixel size and I don't have any trouble loading them. All you have to do is browse, select the pic off your computer and click add the file. You can do three in a post. Great big pics are no fun to view. You have to do too much scrolling.

    To attach a photo, you could open a free Photobucket.com account and upload your photos to their site, using their instructions.

    Once there, you copy the "IMG code" they give each pic, and paste that code into your message here, and the pic will appear.
