Silicone matt in sump?

[PghReef]

Looking for a mat under the return pump. Dont want to use anything that can cause issues but they all look the same to me.
Any food grade silicone mat should be safe right? Found these for cheap

any food grade items should be pretty reef safe.

Probably best to get an OXO rather than the no name items.
