Diatomaceous Earth Question

[thunderdood]

Does anyone know if using Diatomaceous Earth around the house to control insects pose any risk if it gets into an aquarium with fish and corals?

Nope. You can buy a water polishing filter that uses it inside your tank. Won't hurt a thing.

Worst it will do is add a little silicate.
