Aquarium safe wood protection
I'm making my own aquarium table with a nice looking oak table top. I was protecting the bottom side from moisture with a plastic they use in construction (before pouring concrete they put in a plastic sheet to prevent moisture being sucked out of the concrete --> that stuff).
However it looks hidious. I now want to take the plastic off but I need to find some sort of an oil that is aquarium safe.
I have a food-safe lin seed oil used to protect butcher blocks..would that be something usable? I do not want to add toxins to the water because of my stupidity..
Thank you for any remarks or suggestions!
