Thanks all for the feedback! My xenia is still hanging in there... I have moved it everywhere in my tank, closer to the lights, in direct current.. you name it, its been there. So far I get best results at the bottom of the tank. I have an Iodine test kit on its way. I suspect that this is the parameter thats off... I had 2 emerald crabs and 2 peppermint shrimp. The shrimp just simply disappeared. The crabs died a few weeks apart. They never tried to molt and I fear the Iodine wasn't in the tank for them to. I have been dosing with Fuel for corals and trace minerals on a weekly basis. I also do a Partial water change every week. I do have a Bubble Tip Anemone that I have had for a few months now and its doing great.. I relise I probably need to upgrade my lighting. I wish I had researched the lighting situation before I bought my Marineland double bright from my LFS. :( I like the LEDS I have now, if I go to the Marineland Reef Capable LED will that be powerful enough for what I need? This is all still a learning experience for me and I appreciate any advice given! Thanks!
