Oh dang! I wish I'd read that before you sent my shipment out. LOL! Oh well, there is always next payday!
I know how hard it is to wait for a tank to cycle but snails cannot tolerate ammonia or nitrite and they would most likely end up dying if you added them before your tank is completely cycled.
It shouldn't be too much longer though, just hang in there!! It is really worth the wait even though sometimes it doesn't seem like it.
