Check your snail and crab populations. And you could consider an algae scrubber to grow the algae outside the display. Most of these are large contraptions, but there are some smaller ones that drop into your sump or even float in the display that have led lights and air tubing with an air pump. I used to have a very large one of these, and it was extremely effective, although it created too many logistical problems, but I would try the smaller versions if I had excessive algae.
