Pipe organ help

[sacutshall]

I purchased this pipe organ about two and a half months ago. First month was a little bit of a rough go for it. not sure
if improper lighting or placement but rarely extended the polyps.
After I got it I upgraded from a 7 gallon tank to a 30 gl tank. On the small tank I had a kessil a80 tuna blue.

On the new 30 gallon tank along with the Kessil I have added a coral life high output T5 dual lamp 24 in. I have to say adding the T 5 greatly improved the look and over all health of the corals.

So I guess my question is the pipe organ outer edges seems to have no live polyps. Should I chip a- way the outer edges or possibly will it regenerate new growth in the old tubes?
Thank you for any and all advice.

The red in the skeleton is from iron. An ICP test would probably be a better course of action. After you get the water for the test, a good stop gap might be water changes.
