I think I understand most of what I've read, but just wanted to confirm a couple things:
1. If shocking with bleach, I want to get my level up around 21ppm, correct.
2. To figure the proper level, I use the Pool Calulator and put in my existing FC level (say 4 or 5) and then put in 21 form my goal, correct?
thanks in advance......also, I tried searching for the answer. If anyone has "how to shock with bleach" bookmarked, and if it's not too much trouble, send it along.
