Did boiling them spoil them at all ?

Hi Alan

Don't bother boiling them, thats just overkill. However, there might be some
remains left in the shells of whatever was inhabiting them at some stage.
Fill a small bucket up halfway, add some salt (alot) and let them sit for a
week, replacing new water every 2 days or so. The shells will be fine in the
tank after this.
If you have enough shells you can crush a few them, put them into an old
nylon stocking and add that to your filter aswell. The more the merrier Imo.

If you ever come across crushed coral at the LFS this can be added too in
liberal ammounts.
