Pet Forum / Aquaria / Goldfish / February 2008Seashells In My Goldfish Tank
I have a beautiful, big cameo conch shell in the tank, and a few smaller ones. Will my goldfish be okay with ocean shells? LuAnn > I have a beautiful, big cameo conch shell in the tank, and a few smaller > ones. Will my goldfish be okay with ocean shells? > > LuAnn It makes no difference tol them..........although unless periodically cleaned the shells can become a source of holding bad nasty pathogens since they are essentially dead spots filled with water and detrius. It happens in saltwater tanks that empty shells harbor high nitrate problems and its certain possible in a small freshwater tank as well I'll clean the shells along with everything else. Thank You. Lu I was told too many shells would cause the ph level to go through the roof.

They act to buffer (add KH) the water, which keeps the PH from crashing as your water gets dirtier with age. I keep Aragonite (crushed coral) in my Goldfish filters to keep the PH up. With weekly water changes the PH stays somewhere around 7.6. It's unlikely that your shell would have the same surface area as crushed corals, so it would have much less impact on the PH. I have quite a bit of Limestone in the pond, which keeps the PH around 8.6 and the fish don't seem to mind. Thanks Bill what Bill says... but I will tell you that IF the pH of your water out of the tap is below pH 7.0 or so that conch shell will dissolve rather rapidly.
