Calcium Hardness too high, cloudy water and / or scaling may occur.
Draining SOME water will help.
NEVER completely drain your pool.  Serious damage will occur.  Always check with your local pool builder.

All dosages are approximate. Remember to retest the Total Alkalinity the following day, letting the filter run continuously & adjust as necessary.

Remember that the source water for filling your pool can have certain properties that can cause chemical changes as you top off your pool; especially calcium hardness & metals & minerals.  If your tap water is "soft" or "hard", those chemical make ups, make a difference.  The use of water softeners makes a difference.  PLEASE tell us this information when you contact us so that we can better help you.
