Once again, I am Miss Confusion. After studying the "Swamp to Oasis" article for the millionth time, I'm still a little baffled. I get that the PH should be leveled first, and FC should be at "shock" or "algae shock" levels. And if CYA is below 20ppm, I should add 20ppm. What about the other chems? Am I supposed to wait until the algae is gone to worry about them? And if so, how long do I wait to get them straight? Hopefully beginning "shock & awe" process Monday, so need help quickly!!
