Then enter your current FC level is the Now column of the yellow FC row and your target FC level in the Goal column of the yellow FC row. Then select the kind of "shock" you are using in the popup menu to the right, it probably says "trichlor" right now. Then, just to the left of that popup, it will tell you how many oz by weight and by volume that you will need.
Thanks. I followed your directions and got an answer (about 6 lbs).
I am wondering if I have Mustard Algea. Do you know where I can see a photo of it? To get rid of it requires an algeacide containing copper, right? (Has anyone tried placing copper tubing in the pool instead?)
