When testing CYA level, do you take the reading when you can no longer see a defined dot at the bottom of the test tube or when you can't see any hint of grey at the bottom? Does it matter if you look away and look back again? (I know that sounds funny but sometimes I think I can't see it anymore and my eyes feel fuzzy and when I look back I see the dot again)
I'm in TX and we have had extreme rainfall this year and I ended up with extreme algae. I started treatment about 5 days ago adding bleach and I added "pool conditioner" that came with my pool to raise the CYA because it was low in the initial test. I ended up with CYA around 70 to 80 but not sure how accurate because I had also added lots of bleach. My water turned a milky white the next day and it started raining again. (We have been in extreme drought for a few years and as soon as I have a pool we are getting record rainfall and flooding)
My water was remaining milky and last night my clarifier finally arrived and I hoped to wake to a clear pool. Last night I had a FC of 23 and CC 0.5.
This morning I can see the bottom of the pool but the water is still cloudy. I could also see a little bit of algae left over on the bottom which easily stirs up with the brush.
This morning the FC is 18, CC 1.0, CYA 50-60, PH 7.5, TA 100, CH 300, Salt 3400. (After taking the water sample this morning I dumped a gallon of bleach in which is about twice as much as I should have according to pool math- I think I was angry at being able to see algae again LOL)
I want to be sure about exactly when to read the CYA level so I know an accurate FC level for the SLAM.
I added the clarifier about 12 hours ago at double the dose rate as allowed for extra cloudy pools. How long before I can add more?
I am beginning the think there is no chance of swimming tomorrow either
