Thanks for posting up a few pictures! You have quite a bit more in your tank thank I thought. It looks like you have some mature liverock. What kind of lights do you have on your cube? Hopefully after another few months your diatoms will disappear with normal water changes and maintenance. Do you have a vision for what you want your tank to eventually look like and consist of? I have the same hammer coral as you and it grew to the size of your tank in 2.5 years. I'm assuming it won't take long for the xenia and mushrooms to start growing in places you won't be able to pull them from, lol. It took me a 2 years to pull a Kenya tree coral out! of my display.I've had it suggested to me to join our local MASNA approved group, do we have one? Should we start one?
I think the xenia will fill up whatever empty spaces you have, lol. The hammer is a great coral to gauge how the tank is feeling. If it's big and beautiful then life is good! If it's retracted then somethings up. Mine has always been a great addition to the tank. What kind of lighting do you have? Plate corals seem to be very difficult for many reefers to keep. I didn't notice yours in the photo. Is it still in your tank?well, drag and drop didn't work, maybe this will post a pic
