Aquarium safe silicon grease???
I read on here somewhere that silicon grease was safe for aquarium use.
Is this true?
What kind of silicon grease and where do I get it? The only thing I have found locally was a silicon spray lubricant, but it contained petroleum distilates, which is a no-no (can you say 'oil spill'?).
I did find some 'dielectric grease' in an auto parts store, which I beleive is silicon based, but the package did not list the ingredients so I did not buy it.
What I want to do is lubricate PVC threads. When test fitting the PVC I find that it goes part way and then gets stuck before it is tight enough to be water tight. Would it be ok to do this AND use teflon tape at the same time, or is the teflon by itself sufficient.
