I saw the other posts about green pools. Not sure if it is weather-related this year.
I have dealt with green pools before and it usually went away after a couple of weeks. This year the problem lasted the good 2nd half of the summer and it just never goes away. Now it's time to close the pool. The decision is to close a green pool or try more...
TC .5 or less
CYA 70-100 (I ran out of reagent, so the ready is a week old)
It's vinyl pool with about 25,000 gallons.
The NJ weather is usually dry and leaves started fall down in the middle of the summer. I SLAMed the pool early on but it might not have been aggressive enough. I also used the chlorine tablets which contributed to higher CYA. I have stopped using the tablets and used only liquid chlorine and powdered shock. (I also tried Kem-Tek KTK-50-0006 Pool - which I usually use for pool closing. I was desperate and also tried Natural Chemistry's First aid. )
The green pool has lasted 6 weeks. I am going to give it another week or 2. I will raise the chlorine level again to 20 to 25 for five days to see it makes any improvement. I have to cover it with a net because the leaves have become uncontrollable. (Pool is surrounded by trees). Please share your thoughts.
