    White chalky film

    I have a white chalky line on my travertine behind my waterfall and along waterline and vertically on each ceramic tile seam. How do I remove it and prevent it from coming back

    Welcome to TFP. If you want to take control of your pool and get away from the Pool Store, you're going to need a good, reliable test kit which you can look at here Test Kit Comparison. We recommend you go with the TF100 as your will be getting more reagents with the kit than with the K2006.

    Your CYA is very high. We will *ALL* recommend you do a drain/refill/retest before moving on.

    Also, it is recommended that you become familiar with the ABC's of Pool Water Chemistry.
    I'd bet you my bikini you'll never get TFP water from a pool store!

    Can you post a pic? That would be very helpful.
