Big storm last night. Cleaned pool and pumped for 3 hours before testing. "Pool Guys" have been taking care of pool weekly for 2 weeks and just came Thursday and added 1 gallon muriatic acid and 3 lbs granule dichlor chlorine. Here are my first test results!!
Calcium Hardess - 120
Free Chlorine 9.8
Combined Chlorine - no combined chlorine-sample did not turn pink
