No Coral Growth in Months and Months

Hello to all,
I have a 65 gallon w/ 20 gallon sump reef that has been up and running for over a year now. I have had good luck with everything so far(knock on wood), no coral or fish deaths, but just haven't seen any growth to speak of with any of my corals. They just live and that's it. Some are not nearly as colorful as when purchased. This has been dissapointing especially in the last couple months because I have been trying everything. I have replaced my original t5 bulbs w/ giessman brand. I have built a custom canopy that has housed two par38 rapid led bulbs since christmas, along w/ the retro 156 watt t5's. I have ruitinely done 5 gallon water changes weekly and I target feed once a week. Is there something I should try doing?
Everytime I get my water parameters checked they are spot on.
My corals are xenia(has shown the only growth since purchased), gsp, frogspawn, fox tale, zoas, trumpets, open brain and a red cap.
Any ideas or questions about my system would be appreciated.
Thanks,
Kyle

Don't worry. This happens. After everything settles in really good, they will take off. Just give it time time..

Cal and Alk might be a little low, I add fuel by aquavitro a couple times a week, it really makes my coral pop with color and growth

I would bring up cal and alk. Also check magnesium.

Before adding cal and alk, you need to CHECK and see where you stank on your parameters. You don't want to add anything if it's already stable at a high range.

My 300 is LOADED with corals. If I run into a growth problem it is usually because a nearby coral is fighting back. Xenia is especially sensitive to some other types of corals in the tank. It would not grow in my display reef, but when I moved it to my algae scrubber a few years ago, I have been harvesting it and selling it to my LFS. Soft corals are pretty notorious for affecting the growth of hard corals around it, at least that is what I have seen.

Nobody seems to have mentioned phosphates.... Don't forget that if they are above an acceptable level they will inhibit or possibly completely prevent calcification/growth.

You could have perfect cal/mag/alk levels and the best lights in the world, but if your phosphates are high it won't make a blind bit of difference.

I thought he reported water quality was okay...will re-read, but you are right.
