ICP high zinc?

[branbray07]

Hey guys had a question about this icp test from my tank . Its showing high zinc. Is it that high to be concerned?

Zinc will typically come from metals or overdosing a additive. Check for screws; bad magnets; heaters etc. It is for sure high and can cause problems. Magnets I never use anymore because they do go bad and leak zinc.
