question

#1
I have had my tank up for two years. One of the very first corals was this one

It now looks like this:

(the coral under the clarkii)


My question is why did it go from colorful to not so colorful? is it my lighting? The coral has more then tripled in size. My water parameters are good. I have a 4 light T5 fixture. at 54w each. The tank is a 55 gallon, with a 20 gallon sump. I have only lost one fish and a few crabs/snails over the last two years, but all my other corals(only just a few others) have grown and spread out. Its not that big a deal..it is a nice coral..was just curious, because I see all these other polys/ and zoas with lots of color and would like to add more to my tank. Thanks for any insight you might have.

It almost looks like the Palys over grew the zoas...

Because in the first picture you can see the greenish brown palys...

Don't know, those look like grandis in the first pic. The second looks like some kind of green Zs.

I've heard of dosing vitamin c and/or iodine to help with color. Never had success with vc, just made a white film on my sump.
