i too have had dreams of recreating a non-tropical pacific coast tidepool
but, the commercial availablity of stock is virtually non-existent and the information on the subject is limited...you would be a pioneer of sorts...
not to mention, i think setting up the necessary equipment to replicate the tidal flow and the temperature ranges would be quite the project ($$ and time). All that said, it is still something I would like to do some day. One thing for sure, those tidepool critters are a lot hardier than reef critters....the temperature and water quality fluctations in a tide pool are quite dramatic, unlike the notoriously stable reef environment
