aswetich,

You got some good ideas from b=c?. To get even more help, please post a full set of chemistry numbers, including FC, CC, Alkalinity, and Calcium, in addition to the CYA number you posted. Also post the size of your pool, the hours of sunlight it gets, and how much stuff gets deposited in it (leaves, dirt, etc.). Have you had any recent algae infestations?
