I live in a condominium with a 11.000 gallon in ground pool.
We recently drained and painted the pool. It then got filled up, but the pump wasn't turned on nor was there any maintenance.
Leaves build up in the bottom of the pool, stained the paint and started to turn green.
Then the pool maintenance guy told us to add 5 gallons of liquid chlorine to prevent algae. Nothing else was done in about two weeks and the maintenance guy hasn't show up anymore.
Friday I figured out how to start the pump. Removed all the leaves floating and in the bottom. I also vacuumed as much as I could.
I bought the TF-100 Test Kit. Performed yesterday the chlorine test (OTO). There was no chlorine and pH was higher than 8,2.
I purchased liquid chlorine and added about 1,5 gallons. I also purchased a powder to reduce pH and added some according to the instructions of the container (but less than needed, to prevent overshooting).
The problem is that the water turned green after adding chlorine and has stayed so since yesterday.
I don't know if the problem is due to minerals in the water, the high pH or the absence of CYA.
Today I did all the tests in the TF-100 kit:
Chlorine (OTO): over 5
PH: nearer to 8,2 than yesterday, but still above
CH: 400 (water is hard here, so I think replacing it won't lower CH)
TA: 60-70 (pinkish red)
CYA: 0 (filled the tube to the top and still could see the dot)
┐How can I turn the water clear again?
┐And in which order should I try to get the values in the desired range?
