Acclimatizing snails

[TAZ]

Hi all,

I was wondering if you could let me know how long you take when you are acclimatizing your snails. I recently went through a bit of a disaster with my tank after I added some "cured" rock from Big AL's (turned out it was not as cured as they claimed, caused my tank to go into a cycle and killed all my corals and snails - but amazingly none of my fish...go figure. I am not to happy with these guys...but that's another story). Anyway, the tank is all back to normal and everyone is happy, so I started to add snails but the batch I added had all died within a couple days. My water specs are totally fine and everything else in the tank is doing great, but not the snails. I did some research on the net today and discovered that snails need a long acclimatization process (5 - 10 hrs apparently). Have other people had this problem? What process do you follow when you are adding sails

Thanks
Martin
