I recently allowed my CYA levels to creep into the 150's and it backfired with algae outbreak. After diluting and refilling, got my CYA back to 56 (manageable I believe). Since then, I've been fighting with shock (shocking w/ 3lbs ever 12 hours for the last 48 hours) to get back to normalcy, but since it's not working I think it's time to try SLAM for the first time. (I'm a brand new member.) My levels are currently good (CL: 6.4, pH: 7.4, Alk: 90, CYA: 56 17,000gallon inground pool), so I think I'm ready, but before I start I have a few questions.
For my SLAM treatment:
1.) Considering I have to maintain a higher FC level with 56 CYA vs. a lower CYA, is it more cost effective to start slam now, or get my CYA even lower for a better starting point to decrease expenses needed to cover Chlorine costs? (Water cost vs. Chlorine cost)
2.) In the SLAM instructions, in the "You are Done" section, do ALL those criteria need to be met, or just 1 of them?
Thanks in advance. Excited for happier pool days ahead.

- For the overnight loss test how am supposed to conduct that if I'm needing to maintain a CL of 24ppm. Do I wait to do that until visible algae is gone?
- If I am looking for a CL loss of less than 1.0ppm overnight, How long might it take for that that CL to drop to a swimmable level? And what do ya'll consider a swimmable level (Forget minor irritations, I'm not worried about that)?
