Is your salinity really .35? If so that is way too high! You also have a much too young tank for anemones - they can't handle swings in parameters, particularly sail to and temp. What kid of lighting exactly? Anemones also require very strong lighting... What kind of fish do you have in there and how many? If the salinity is really that high I would say that is your main problem. Do you use a refractometer or hydrometer?
