Hi Mr. Mooks, If you would be kind enough to post back with your current Water Temp, I am sure you are o.k. to add your salt now if your water is above 60° F. JimK is right, however, Low water temp can give false measurements if you are relying upon your Controller. My Compupool CPSC24 has an idiot light that tells me that I have low Salt, and that light stays lit almost all winter until the water warms up in the Spring.

What is your actual Salt Reading? How are you measuring it?
