How do I tell if I have too much light?
I've had my LED's on my tank for about 3 weeks now. It is a 90g and I have 72 Cree 3w LEDs, 40 RB abd 32 CW.
They are running at 100% right now. no optics, 10" above water. My coraline has turned white at the top half of the tank now, and my zoas are melting, my birds nest and monti's look really great though, same with my bubble tips. Now it looks brighter then my old T5's, but how do I tell if the coraline is bleaching from too much or too little light? I am pretty sure I have to dial it down, and will do so, but don't want to go the wrong way. |
