My Tank Thread
Welcome To R2R, I agree with @dbl one Hydra 52 is not enough.
I run 2 hydra 26 Hd's on my 48"L x 18 w x 21 D system and my coral growth really took off and with also changing my chemistry products that I am using. My old LED just did not have the intensity to keep my corals growing or even living. You have a great light, just get another an you will see the difference in two weeks. My setting are below

The Hydra 52 is a very weak light, at only 90 watts @ 100%. It appears you are running it at only 50% and I'd doubt you are getting enough par in the center, let alone the sides of the tank. Here's some info on the par output:

Despite our parameters differ I cannot see that you are very off in terms of parameters. No3 could be a little lower but I have ran tanks with higher No3 than that. Last time I tried DD H2Ocean, some 4 years ago it ended in the bin as it was not approved by my corals but I heard it has improved since then.
Make sure you keep everything stable, if you skim wet, make sure you are not replacing the collected skimmate with just RO/DI water from the ATO that will impact all your parameters ( sorry, I am a freak about stability) time to time test for K, it should be around 400/410 for a salinity of 35ppt.
If you try to keep your Alk low, do not make water changes using a salt with a much higher Alk. Try to keep your parameters stable Ca 400-450? Mg 1460 -1520? Why such variation?
It is so hard to comment on other people tanks, I am always afraid I could be off. The fact that you are here trying to find what is going on is very positive and I am sure you will get things right rather sooner than later.

In that article they compare the much weaker and older Hydra version, not the much better Hydra52.
I ran the old Hydras for about a year, growing SPS without big problem but didn't like the disco effect and the fact of having to replace some of the LED's almost every single month due to overheating issues.

Sorry, I am not trying to be mean. I never had Xenia, so I can't help about its reaction to increased light, having a mixed reef like yours is way more complicate than having a SPS tank. I hope I will never have xenia in my tank... it is like the plague! lol
yes its photosynthetic
I have xenia at the same level in my tank as acro and other SPS. around 500+ par. High exess nutrient and low flow yae they can get out of control. CLove polyps will do the same. Pretty easy to control,
