I'm concerned about my pool water for the first time in the almost 3 years we have had the pool. It's a 9300 gallon concrete pool. It has a salt water generator. After about 6 inches of rain yesterday in a 2 hour period I noticed this morning that the pool water was a light green and slightly cloudy so I immediately tested the water and turn on the superchlorinate function. I didn't see and combined chlorine so I was curious if the green I'm seeing is algae or not. I also was unable to get a good CYA reading. My last reading was 70 and I haven't added any to the pool but my reading was over 100. I'm still running the chlorinator and haven't tested the pool water again but here are the readings from this morning:
PH - 8.0 (I've added acid to take care of this)
FC - 2
CC - 0
TC - 0
TA - 60
CH - 410 (I know it's high, my fill water is the problem)
CYA - 100+ ?????
Borates - 50
Salt - 2300 (I had to add salt)
So am I on the verge of my first encounter with algae or am I ok?
