When to Shock?

[duraleigh]

My question is, do I just bring the FC up to 15 ppm and let it return to normal, or do I keep adding until I can to maintain 15 ppm overnight?

overnight

overnight

Dave, I just wanted to check, you say "overnight", as in, keep adding until I can maintain shock level overnight?

Yeah, sometimes I sacrifice clarity for brevity.

If you can hold Cl levels overnite, not dropping more than 1 maybe 2ppm, that will tell you you have finished killing the organics in your pool.

Only AFTER that occurs should you let your Cl go back to maintenance levels.
