Beach Shells for tank ?


Can I use shells from the beach for my multi tank?

I live on an Island so I'm close to the sea and I often find some very nice shells on the beach and while diving, could I boil them and then add them to my tank or is this a bad Idea ?


After you clean them I would put them in a small bucket or bin of some of your tank water (that has no fish in it). After a few days, monitor the readings. Does it affect pH, kh, gh, ammonia, etc. If it is fine, I would assume you would be safe to go. :)
