Elevated values of metals in ICP!? Removing bioblock - Cause and effect!?

[Dimorb]

My main suspects...

Bio-blocks from maxspect
denitrification blocks from maxspect
Pollution by balling preps - all chemicals are food grade but from what I've read from you @Randy Holmes-Farley in this: https://reefkeeping.com/issues/2003-04/rhf/feature/index.htm that doesnt mean it's "good enough"..

I prepare myself for reducing / removing the bio blocks and the denitrification blocks and perhaps have a ICP test done to my balling solutions.

Dont know if I need blocks after the system is mature.. keeping all kind of corals in 2000+ liters of volume and only 6 fishes.

Also ordering in ICP test from marinlab, ati, triton and smart ICP to cross check values.

Using metasorb and thinking of trying Triton detox.

Does anyone have any other suggestions on what to do?

I think I can only repeat what I have already said:

I'm not convinced those values are any problem.

Not all ICP testing is accurate.

Those blocks are sometimes fingered for boosting aluminum, but not typically other metals.

Food grade does not absolutely guarantee lack of problematic impurities, but it is rarely a big problem because it does have to pass a maximum metals test.

Metal binders (polyfilter, metasorb, cuprisorb) are a good choice if you believe you want to try to lower then further.
