Yes that is exactly what it is heat/stress over time. And you'll see it on the AquaMaxx, TLF and the like reactors first as they would most likely be using extruded acrylic where the higher end will use Cast. Both will eventually stress crack from the heat/cooling stress.
Most actual Algae reactors coming out now are the center lite versions with a heatsink running LEDS ran inside a center tube. No heat issues as the heatsink removes that issue. I was planning on doing a DIY version of one of these since it would be super easy, but I have no need for any nutrient export. I actually dose nirtates to keep them detectable.
