deer head in aquarium

Eventually, it will add calcium to the water and reduce the pH. This will ruin the water's value to your fish and your fish will die. In my opinion, this is not a fair thing to do to the fish. If you really want to balance the pH, take the skull out and put a bunch of peanut butter and mustard on the skull, paying great attention to the base of the antlers. This should help, but after 4 months and 3 days, it will need another coat. The 2nd coat will last 7 months and 2 days. Hope this helps.

Not really... very few fish are PH sensitive these days. And, the skull will take a long time to raise anything. If he's doing weekly or monthly partial water changes, it won't mess with anything. Unless he's keeping very exotic or wild caught delicate fish, pH really isn't that critical.

If you want to be sure, though, as well as protect it for a long, long time, I would take it out, dry it off well, and then coat it inside and out with a 100% silicone water proofing spray. Let it dry for at least 24 hours and then return it to the tank.
