Default Fluval external filter gasket

I have a Fluval 305 external filyer, and part of the maintenance routine is to ensure that the gasket is lubricated. With what are we suppsed to lubricate it with, which should still be safe for fish? The instructions suggest petroleum jelly. Is this any special petroleum jelly, or would Vaseline do? I always thought Vaseline is medicated, which could be harmful to the fish if dissolved in the water.

Information

Unilever do a few products under the Vaseline name. On their website http://www.vaseline.co.uk it shows the pots of Vaseline Petroleum Jelly as 100% pure. (Mineral oils, paraffin & microcrystalline waxes - apparently - no medication.)

Hope this helps.

I think vaseline is a trading name but you can get petroleum jelly quite easily from chemist and supermarkets
