Reef putty and ICP tests

[Mortie31]

Hi All, just seen this question asked on Fb and it made me think, does anyone know what the common reef putty’s contain and what if any effect they would have on ICP testing? Would the effect be temporary or accumulate? If after using how long should we wait before submitting an ICP?

I wouldn't imagine they would throw off an icp test but it would be intersting to see a before and after.
