Conflicting ideas.

+ CuLator removes the metal while it's dissolved = lower pH + HEDP

+ Cal hypo via the skimmer removes the metal onto the filter = higher pH

You can't really do both at the same time. If you've used the cal hypo and had some orange (iron) or green/blue (copper) backwash, that's worked. BUT removing metals seems to rarely be a 1-step process. If you've gotten some metals out with cal hypo, good. If you want to continue with it, that's fine, too.

Once you start with the CuLator, a lower pH would be better.
