View Full Version : Adding shells from the gulf to my Tang tank??

I currently have a bunch of really nice shells I wanted to add to my 55g Tang aquarium. They are sitting in a bucket with a cup of bleach and some water to remove bacteria. I wanted to add them to my tank for the visual benefit as well as benefiting my shell dwellers (neolamps). I've heard some talk of adding shells from saltwater increasing the calcium carbonate content of the tank chemistry in fresh water tanks. And basically that this could kill or harm the well being of the fish. Is this true??

Not with African Cichlids! They love hard alkaline water....

Ok, so its fine then...... Correct? Since this would make the water more alkaline...

I am still learning but have a many beach shells in my african tank with no problems so far.

I have had them in other tanks before and they do grow algae very fast, but depending on the shell can look even better.

Not to steal the thread, but I was thinking of putting them in my sump as well to keep the hardness up. An afternoon walk and I can fill a bucket easily. Anyone have thoughts?
