Non-Reef Safe Silicone Disaster Cont.

[Randy Holmes-Farley Verified Community Expert]

I expect that many forms of tin compounds are toxic, but I do not have any info on which are worse than others. Tin is far more toxic to marine organisms than people.

The amount that is ok certainly depends on the form, which is what I have to say to every person with an icp test wondering if it is ok or not.

How is this 100% Silicone and contain mold inhibitors?

I know this was an old and maybe even a rhetorical question, but you have to understand what that could mean. It is not intended to claim there is just one ingredient and that ingredient is a silicone polymer. It implies it is only a silicone caulk, not a latex caulk or a mixture of silicone and latex, which do exist. But a silicone caulk is necessarily a mixture of multiple different ingredients that go into making a silicone caulk function.
