Alright guys, time to open the pool. I would love some comments on my plan below. Pool is 10KG in ground vinyl with 1hp return and 120sqft cartridge filter.
- 3 days ago peeked under the cover and saw a green swamp. Dumped 1 gallon of 8.5% chlorine.
- yesterday, water no longer green but very cloudy and dirty. FC zero.
- Today I did some measurements. PH=8.3, FC=0, CYA=0.
Before shutting last November, I generally kept the water at PH 7.6, FC 5, CYA 40. I thought that once CYA is in the water it doesn't go away until you drain? How did the CYA go down to 0?
Next steps:
1. Dissolve CYA to get the level back up to 40.
2. Check PH, if still high use Muriatic to lower to 7.6
3. Start shock at around 16 for a few days until I see minimal overnight loss, then maintain 5.
Advice?
