Get your pH to about 7.0 or 7.2, then your alk (TA) to 80-100. Shock the pool with chlorine, 3qrts. per 10,000 gallons to bring up the chlorine 10ppm. run your filtration 24/7 and backwash once per day until the water is clear. The pH should rise on it's own. If not, add sodium bicarb. http://www.clean-pool-and-spa.com/swimming-pool-chlorine.html
