Pool Water Is Brilliant Lime Green But Crystal Clear

If the pool is a brilliant lime green color but absolutely clear, the alkalinity is low.

Items needed to raise the alkalinity:


1)  Use 4 lbs baking soda per day until the green color is gone.  

2)  Test the pH. 

3)  If the pH is above 7.0 after using baking soda, use liquid acid to lower it again to the low side of the pH range (6.6 - 7.0, aim for 6.6)
