Hello. We just opened our pool yesterday. Everything looked great. I vacuumed out some dirt that fell through the center of our solid winter cover and set the SWG to Super-Chlor. Early this morning I sampled using the TF-100 (note I could smell chlorine while walking around the pool).
As of this morning...
PH (Taylor k-1000) = 7.5
Chlorine (Taylor k-1000) = .5 to 1
Total Alkalinity = 90 to 100
Calcium Hardness = 120 to 130
CYA (stabilizer) = 0
Free Chlorine = 1 ppm
Combined Chlorine = 0
Salt = 1,760 ppm
Temp = 68 degrees F
This evening I scrubbed down what appeared to be algae and then tested for chlorine. It was zero. My swg shows the salt level is okay, although my test strips show 1,760 ppm.
Why is the swg not generating chlorine? What do you recommend? I added a little algaecide (8oz) to the pool this evening. Please advise, as I'm new to the pool world.
Two more things...I have never added cya and I run my pump 24 hours per day.
