Triton ICP - tin?

[Kurant]

Everything else was pretty spot on, except some elements they suggested dosing for, that were still in the green, but close to borderline.

But Silicon which I believe came from my biomedia, because I haven't done any water changes. (I do Triton)

Tin, I've removed all magnets. Checked all MP40's, stripped down the return pump and cleaned, no rust or anything. Not sure what else would cause this? ICP test came back with a reading of 46.. I think that's a lot?

Tin is complicated since there are lots of chemical forms of varying toxicity, but if the tank is not suffering, I wouldn’t agonize over it. Many folks have that sort of level without apparent issue and those that seemingly do have issues usually have substantially higher levels.

Plastic pipe and tubing can be a substantial source of tin which is added as a stabilizer of the plastic.
