Hey all. I've used T5s since I started over 10 years ago. I switched to LEDs this past year when I moved. I have since lost several shrooms, I have an SB Reef black box mounted 9" above the tank over my 60 cube, 24x24x24". I slowly turned the lights up when I got them. I have since turned them down to 10% whites and 50% blues. No matter what I still have shrooms randomly bleaching and can't seem to figure out why. They are randomly bleaching at different levels within the tank. Some are fine, others bleach. Tank is all softies. Pics and parameters to follow.
