lighting

Hello All, I'm looking for help with health on my 240 gallon system. It's been running for 2 and a half years, and I can't seem to have success with my SPS coral (and now appears one of my torches is dying.) I'm attaching some pictures of some SPS coral that appear to be dying. I think my...

Bought it and decided for an alternative

I just bought an Eden X 80. I have not received the tank yet, but I wonder if anyone has tried alternative lighting to the AI Blade that the Eden is designed to use? Specifically, I would prefer the Fluval Plant 3.0 LED for its ease of use and because I already have one on another tank. I tried...

My cycle ended a couple of days ago on my tank, but I’m actually going out of town this Sunday and will be gone until next Saturday. Considering I have no live stock in the tank should I go ahead and implement my lighting schedule while I’m gone or no? I need some opinions on this matter because...

If you scaled your LED blue spectrum(s) to around 100% power, what power would whites be at? For example, I believe Saxby is "some" whites, hanging around the 25% whites when the blues are scaled to 100%. Definitely more daylight than, for example, JF's tanks which are very blue. For MH and T5...
