I'd go with an epoxy sealant. usually you can find some variant of a pour-on (intended for doing coffee tables/bar tops with stuff embedded in them) at most craft stores and Home Depot/Lowes. I've used this stuff in paludarium building, and I've also used it to coat/reinforce a bird skull (not for the paludarium)

Also, vertebrate skeletons are mostly apatite, (I think hydroxy apatite or something, but I'm rusty on this) - basically a calcium phosphate compound. I don't think it would have an immediate affect on pH, but as it is broken down, may contribute to phosphates (I'm guessing here...)
