Hi guys and gals, once again I need to turn to you for advice.
I have what I believe is an Open brain coral, but unlike all my other corals, it seems to be struggling. It has always had two areas of slight tissue resection, however these are getting bigger, and i have now noticed that its hard lower half also appears to be breaking down now.
My water parameters are all good except Nitrate which I do struggle with and seems to float around the 20 mark, but my understanding is that should actually be beneficial to coral??
I have tried spot feeding with frozen food with the pumps off over the last few weeks, I struggle with my tang, wrasse and cleaner shrimp nicking the food straight from the coral.
The coral is in the sand below a blue and a white T5 bulb (the pic gives an idea of the light its subjected to,) and about 15" from a small power head, so it gets gentle flow over it.
Its clearly deteriorating, any advice gratefully received.
