High LEad levels in reef water analysis ATI

[nvictor]

Has anyone seen high lead levels in reef tank
My Ro water test shows no lead but my reef tank shows
High calcium and strontium - i am going to stop dosing REdsea supplement
But what is the cause of increased Lead 6.5 Mic/L - should be 0.10
Ro water testing shows 0 lead.
Any ideas?

How are you testing for lead? I am not sure what would cause such a level. Maybe a bad supplement? Have you added any decorations or the like to the system recently?
