Mirrored glass for sump?

[DiverDude]

I wouldn't risk it. At one point, I believe lead was part of the mirroring process (probably isn't anymore). The coating that is the mirror might flake off in the future and who knows what it's made of.

mirrors use to be made with mercury on the back and then another coating of some thing else they don't do it that way now. most are made with a plastic base to them now a days.

The back of the mirror will contain tin chloride, silver, copper, paint and other chemicals. So not too good for saltwater.
