I am trying to remember the depth of that tank but it sounds fine to me. Some LPS can get bleached even under T5s. Many LPS might do best in the bottom half of your tank depending on its height.
If you find corals bleaching, using a patch of plastic screen door netting directly over the coral, on the underside of the acrylic lens (if you have one) works well. You may need to do more than one layer to get the result you want. Elevating the light will decrease the light intensity as well.
