    Good day,

    Thank you for your message.  Sorry for the delay in responding.

    The best process for clearing the problem is to follow the following:

    1. Balance the water.

    2. Bring the chlorine level up between 5-10ppm.  Keep it there and don't let it go below 5ppm. 

    3. Circulate the water continuously.

    4. Add a double dose of a polyquat algicide (60% concentration would be the best). 

    5. Maintain the chlorine level at close to 10ppm for one week. 

    6. If this is a hot tub, drain down and clean the surfaces.  For a pool, consider an enzyme based cleaning product.

    7. Resume normal maintenance procedures, but keep an eye on chlorine levels.  Don't let them drop below 3ppm for a week or two.  If this was a hot tub, continue using a small amount of algicide for approx. 1 month to help make sure it has cleared.

    I hope this helps.  Let me know if you have any further questions.
