aquarium friendly varnish??

[kostasonia]

Just a question as if someone knows...Is there any aquarium friendly varnish?? Was just wondering if someone can make sure that the objects he introduces in the aquarium are safe.

There are but I unfortunatly can't help you with specifics. Such varnishes (often plastic based) are as an example used in many public aquarium to seal the concrete in their tank and prevent it from affecting the pH values in the tanks.
