I must strongly disagree with the statement that all invertebrates are sensitive to changes in water chemistry and need to be acclimated for 3 hours.Many species commonly kept in our tanks such as Mexican Turbo Snails,Blue Leg Hermits,and Cerith Snails are collected in tide pools(I brought back hundreds of self collected Ceriths and Blue Legs from the Keys last spring)and as such are routinely exposed to rapid and drastic changes in salinity and temperature.My normal acclimation for these creatures is to open the canopy of the tank and see how far back I can stand and still throw them into the tank.That's a joke of course,but you get the point.These animals will sit in a small pool of water,or even out of the water baking in the sun.The temp goes up,evaporation increases and the salinity goes up.All of a sudden a wave makes it far enough ashore to overrun the pool and instantly all parameters are back to NSW.There are enough things for us to spend our time on with our tanks that are critical to success.Acclimating creatures that don't need it isn't one of them.
