You can use either, it honestly doesn't <"make a whole amount of difference"> - <"Is expensive bio media worth it?"> & <"HELX-13/K1 verse Foam in Canister Filters">.

One advantage of using the stuff you are already using is that it will already be populated by beneficial bacteria.

I notice some of you are lubricating seals and o-rings. What are you using for this?

I use Silicone grease. Plumbers merchants sell small tins of it. Or Amazon.


Some use Vaseline, I don’t know how it compares.

Food grade silicone grease. It is safe to use on rubber, petrochemical products may attack the seals.

Just saw @Aqua sobriquet's post, the stuff I have is very similar to that.

I think it is petrochemical based?.... so would not risk it on the material they use for seals.

Eheim used to sell small tubes marked “vaseline” but it’s still unclear exactly what the tubes actually contained. Could it have been a language issue? Both products look very similar.
I’ll stick with Silicone grease as I haven’t heard of any plumbers using anything else on potable water and it’s cheap enough. 😉
