I am a new pool owner, taking care of the pool for 2.5 weeks now. I have been adjusting the chemistry based on information found on this site (thanks!). I am using the Taylor K2006 and TF-100 to check levels.
My initial numbers:
7/22: FC 19, CC 0, TC 19, pH 7.7, T/A 130, CH 500, CYA > 100, water temp 68 F
I realized the CYA was very high after reading some posts on the forum. I was concerned that the Chlorine levels were too high as well. The pool had been maintained with an automatic chlorinator using trichlor tablets. I took out the automatic chlorinator, lowered the pH with muriatic acid, and drained and refilled some water (maybe 15%, not sure how much) to lower the CYA level. I have been brushing the walls several days weekly and vacuuming (manual) at least once weekly. The pump (100 gallons per hour) runs 2 hours daily.
Numbers after above interventions:
8/2: FC 7.4, CC 0, TC 7.4, pH 7.6, T/A 130, CYA 90-95, water temp 78F
A few days later:
8/5: FC 6.8, CC 0, pH 7.7
I added liquid chlorine to raise levels by 2 ppm and acid to lower pH. The next day the water was very cloudy and there was a greenish/ brownish tint to the pool. I assumed this was an algae bloom, so I added chlorine to shock level (39ppm for CYA 90) and adjusted the pH.
My question is, am I on the right track, and how long does it take to get rid of algae? The bottom of the pool seemed to have a film of sediment that I vacuumed away today but the water is still cloudy, yellowish, and dull.
Most recent levels:
FC 35, CC less than 0.2, pH 7.5
Also, my kids want to know how soon they can swim again.
