1. With the metal in solution, you probably want a middle pH, 7.4 - 7.6.

2. Using the cal hypo in *small* doses, via the skimmer (NO FEEDER WITH TRICHLOR!!), can help bring the metal out, on the filter.

3. Don't allow cal hypo to contact the CuLator packs. You could add cal hypo when you clean the skimmers -- but take the Culator out first.

4. I'd put ALL my Culators in the water, maybe 1 or 2 in the skimmer(s) and any others suspended in near a return, or even resting on the main drain. Don't discard them unless they are discolored or gummed up.
