I am very new to pool maintenance and am having trouble raising the chlorine to the proper level in the pool. Both my free and total chlorine are only 0.5 ppm and the SWG is set at the max setting. Should I shock the pool by adding chlorine to boost it? My salt level is fine, it tested at 3,500 ppm.
Also, the pool is less than a year old and about 13,000 gallons, I usually take the water to a pool store on a weekly basis and have it tested. It seems like every week I need to add 3 to 4 cups of muratic acid, is that normal?
Thanks in advance for all your help.
