I'm a novice/new pool owner (1 year in this thing) and trying to learn to avoid mistakes I made last year. I went the local pool shop with a water sample last year and in the process of adding chemicals to get everything in range, my clear pool turned green and I spent a ton of money, and time, getting back to normal.
I would like to go to SWG system this summer but I believe I need to get the pool in range before I start that endeavor.
So...this year's water sample looks like this....
Total Chlorine - 0.2
Free Chlorine - 0
pH - 6.2
Total Alkalinity - 10
Adj. Alkalinity - 0
Total Hardness - 147
CYA - 120
The local pool shop said to first add 72lbs of Balance pack 100 or 36lbs of baking soda to increase the Alkalinity
Then wait 30 minutes and add 1.75lbs of Balance pack 200 to increase the pH
Then wait 30 minutes and add 3 bags of Burn Out 35 to increase the free chlorine
I did this last year, in this order, and the pool turned green. So I think I need to get the chlorine up first but it appears that the CYA is too high and adding Burn Out 35 will only increase that so I'm guessing Bleach would be the better route.
Finally, to my real question - What would you recommend I do, in what order and with how much?
Thank you in advance for your time and expertise....I would certainly appreciate any help.
