Ok, good. Thanks for the pic. It's too blue to see things distinctly, but here is what I think I see:
Maybe 7 large anemones?
Several large Cabbage Coral and other soft coral?
Water streams pointing down instead of up?
Low water flow?
Refugium light illuminating tank from below?
No indication of Alk and Ca levels?
In my opinion, the items above may be having a negative effect on the reef aquarium.
What would I do?
These are just my opinions based on what I have found that works:
Run a cup of AC(activated carbon) changed every 2-4 weeks to remove allelopathic/territorial chemicals and/or reduce the number of anemones and Cabbage Coral in the tank.
Turn the water streams so they point at an angle up toward the surface. (Gooseneck the loc-line and move the Koralia to the other side pointed up so that it's stream and the stream from the return meet at the top to create some turbulence and good gas exchange.
Replace the small Koralia with a powerhead with at least double the gph. (I like the inexpensive 1300 gph MJ1200, currently available for <$20)
Install a shield to keep the Refugium light from shining on the tank. Light coming from below at night messes with animals equilibrium.
Know the Alk and Ca by testing it yourself or bringing a water sample to a hobbyist or LFS. (I would be happy to test your water for free.)
More distinct photos are made with "forced flash" or turning up the white lights/turning down the blue.
Aloha
