I have read the Pool School... likely need another read and I want to shock my pool. I am in the waiting game for my CYA to come up (currently between 30-50 depending on pool store - don't have my TF-100 yet) after adding stabilizer to skimmer. My TC as far as I can tell is about 1. I have a SWG.
Anyway, I have questions:
1. Reading the Chlorine vs CYA Chart tells me my pool should be brought to 24 (lowest on SWG scale), but since I am not there yet, can I shock at non-SWG levels to 16 (based on 40CYA)?
2. I have found different results for this: when can kids swim after shocking? If I shock in evening, by the next day? When levels return to ???
3. I think my SWG should be turned off when I shock. Correct?
