I recently switched to a 36" Tek Light. My previous lights were the T5 Coralife PCs.
I'm running two 10ks, one Super Blue, and one Actinic bulb. Alot of my corals seem to be staying the same with some corals not extending as much.
My guess is that when the PCs were in use, they needed more light so they extended more? This is what's happening to my Anthelia.
What are your Tek Light experiences? Did you have massive growth after upgrading to them? After 3 weeks, everything is still the same so I'm fairly disappointed with this light
