My Lighting Spectrum??

[Eb0la11]

Edit*** Ok so I dont think it has anything to do with my lighting. See page two, post number 16 of the forum for info on my water parameters. That's now what I need help with. Cheers!

Hey guys,

so my corals are not doing that well lately and Im trying to figure out what has made them go south a bit.

I can attribute it to either a bit of poor water quality, which has been rectified lately, though Im still not dosing but have changed over probably 40% of my water in the last 3 weeks, but I think it might be my lighting.

For example, my candy cane coral is showing little to no colour. It opens up fine at night and I feed about once a week, but it has no colour. Nor does my pulsing xenia anymore and it has shrunk.

My light is a Coralife AquaLight Pro with 3x 250W MH and 4x 96W Actinics that run for a 12 hour period every day.

My tank is 24" deep and my light is 4" off the surface. So my candy cane is probably 16" from it right now.

What do you guys think? I need to learn what "high intensity" lighting would be, would this be like right near the surface or what? Where is my medium intensity light range?
