Delphinus,

I run polyfilter on my replacement saltwater. I run polyfilter on the main tank, but I don't do it it very often. I guess my strategy is that the main trace elements are coming from my salt and water...I just remove it from the source with polyfilter and RO/DI. I guess this is a bit more cost effective.

Poly filter is similar to DI resin...not quite the same, but it is roughly the same idea. The poly filter has certain types of materials that will attract certain types of ions. Stuff like Copper, Lead and Heavy metals are not usually desired in water, so the makers of Poly filter synthesize a filter that targets those unwanted elements. Of course, if the makers don't target a key bad metal (say....Uranium), then it probably won't get filtered out.

Hmmm...just had a thought...anybody still using water conditioner ? Water conditioners are suppose to break down heavy metals in water.

That's my 2 cents.
