Guys -
I need your help here... So, I skipped a week of pool testing. I tested yesterday evening late and found my values as listed: (see my logs as well)
FC: 2.5
CC: 0.0
PH: 7.8
TA: 60
CH: 375
CYA: 30
BOR: 45
Temp: 72
CSI: -.06
Now, here is the interesting part, I noticed a little green algae in places that are known to grow it if things get out range or something odd happens. So, I did a slam shock with the TFP app and it indicated, based on my current CYA levels, to add right at 4 gallons of bleach. I did this and after almost 2 hours of run time in high with all pumps and features on high to help facilitate mixing, my FC only rose to 7.5 and CC was .5. So, I used the app again and added 2 additional gallons of bleach (12.5%) before hitting the target of 13 (actually overshot it by .5 fo 13.5). This morning, before sunrise, I re-checked it and it did not move and the CC was 0. So, we have a successful over night chlorine loss test. I did take the PH down before all this and as a result lost 10 points on the TA but I am going to adjust this morning with about 45# of bicarb. My question is why did it take so much bleach to hit the slam value of 13.0 (13.5) when the app, based on current CYA, etc. indicated that I only need about 3.75 gallons of chlorine. I ended up putting 6 gallons of bleach in the pool to reach the 13.5 of FC. Now, I have Supreme plus and enzymes from Orenda in the pool, but other than that, nothing else. Is there something in the pool that used the chlorine to oxidize it possibly that fast? The water appears clear and no known issues. Any ideas? I have a chlorine injection system that I am installing now, or in the slow process of installing on the system to automate this stuff. I do not use trichlor and control CYA manually.
First, I thought that the size of the pool was off (gallons). I built the pool. I used a flow meter to fill it but, last night I second guessed the volumes I had recorded and used google maps and the measurement tool to find the total area in sq ft. I then converted to cubic feet and it came out to almost the exact total that I have. So, I have eliminated that possibility.
Any ideas!?!?
Best,
Jeff
