I'm trying to find out if I can use Teflon grease on my O-rings in my new skimmer. Is it safe the little info I can find days it's chemically and mechanical stable. What ever that means????
Thanks for taking the time to reply. I understand what your saying and the point your making. But there are a lot of things that would be safe for us to use to handle our drinking water but not necessarily good for our reef.
But does seem like to consensus is to use Silicon grease. It's cheap enough.
