I added 1 teaspoon of chlorine to 1 gallon of pool water. I took the sample around 5:30pm. At 12:30 pm I did put 16 oz of a sequestrant in. At 8:30pm, no color change.
There are 6 tsp in 1 oz. I don't have a calculator, but that would be a concentration of 1:6*128 = 1:768 I believe.
If it takes me 149 oz to get a FC of 3 in a 24000gallon pool then that would roughly be 150/125 = 6/5 gallon to 24,000 g. So that would be 5/6*24000 = 5*4000 = 20000, so a concentration of 1:20000 so the teaspoon example is way, way more concentrated yet no reaction.....that leads to what in the world could be causing this green haze when I put in a 182 oz jug of bleach?
The container says sodium hydrochlorite - 6%, other - 94%.
It's well past time for me to clean my filter. I put 2# of cya in on Sat and am trying to wait until this Sun to clean it.
Monday
FC 0
CC very, very light pink haze
TA - 70
CYA - was 20, added 8# then later 2# to get it up to 70
pH - 7.2 - this has held steady since I put the citric acid in about 3.5 weeks ago.
I have since changed my swg from 50% to 60% and my pump run time from 4 hrs to 6 to try and get more chlorine in the pool. On Monday at lunch I put 1.5qt of bleach in, another 1.5qt at supper, and another 1.5qt at about 6am Tues. The pool had a green haze to it the rest of the day. The water is transparent. I had previously said 1qt each. I measured the cup I used at about 16 oz instead of the 12 that I recalled. I put 3 cupfuls in at a time.
Last summer I put sand down, then flagstone, then a mixture of crushed limestone, sand, portland cement, and buff masonry cement in as joint filler. THis is about 8' from the pool. I've noticed some sand in teh pool and more noticeably when I clean out the polaris bag. That's about all that I can think of. No fertilizer close to the pool or anything like that. THere are some pics on a thread in equipment I started this morning about bubbles from solar system that shows some of my geometry in the event the adjacent hardscaping is relevant.
