HELP!

My 40 gallon fish & reef tank has been set up for about 3 years. Over the course of the last year, all my snails died off. I had also purchased a small abalone, which lasted only weeks! And had no luck with a clam. My fish and soft corals seem to be fine, with the exception of my GSP, which is shrinking.

I had my water tested at a reputable shop, all was good, but they checked only the basics.

40 gal. w/skimmer, hang on refugium, 15 gal. sump w/sock P. skimmer Rio 2500 pump & rock.

Anything I should look for or test for?
 
You may also have some kind of nocturnal predatory whelk in your tank. They look a little like nassarius. I suspect I have something similar in my 40 gallon. Can't keep snails alive in there for very long.
 
Do you actually have any algae? Remember, its their only source of food...


edit: also, acclimation can play a huge role in their survival as well.
