In re-reading my post, I can see where it might suggest that you use both a trichlor puck AND the culator in the skimmer. I did not mean to do this. (Sometimes my mind works faster than my fingers, and I was in a hurry this afternoon when I typed this.) What I meant was that you can either use the metal sequestrant and try to run the water past a trichlor puck to drop the metal out on the filter, OR you can try the culator and let it trap the metals--not both.

Sorry for the confusion...
