I thought I could do this, but this morning I had 0 chlorine-nada, zip, none! Pool is 2 months old-I just took over from the pool guy to try the BBB method. I did the overnight chlorine loss 2 nights ago and only lost 0.5. Here are my numbers from yesterday morning (6/1):
So, I added 1 gallon of Clorox bleach (6%) directly to the pool water. I turned the auto chlorinator to 0 (there were 3 small pucks left in there). A couple hours later I added 15 lb. of Hardness Plus to increase the CH. I retested the chlorine in the afternoon and it was at 6. I thought things were looking ok till this morning.
My numbers today: only change was 0 chlorine and CH was 200. I retested the CYA and I think it's 60, although at 70 I could just barely see the black dot so maybe it's higher.
Could the Hardness Plus have wiped out my chlorine? This happened a few weeks ago after heavy rain (wiped out chlorine levels) but no rain last night-just the boys playing in the spa and swimming.
I added about 2.5 gallons of bleach this morning. What else should I do?
