hermit crab shells

[minkin]

So I have 5 hermit crabs in my 30g tank.

I need to get some spare shells for them to 'move house'

My LFS doesn't have any in and I'm wondering where I can get them from.

Would these from Petco be any good or are they not suitable for saltwater?

There good just soak em in water and rinse them out real good.

What water should I use...r/o? Or water from my tank?

Your gonna shake all the water off before you put them in the tank. Tap water is fine. You might add 1-5 drop of rap water go your tank. Big whoop.
