My Lighting Spectrum??
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? Last edited by Eb0la11; 01-26-2010 at 11:13 PM.

Yeah I would guess so too, I'll need to get some test kits and take some readings pretty soon here, might need to start dosing if I wanna keep corals.
Does anyone have success with corals without dosing in a similar setup with a good light, good skimmer and frequent water changes?

Alright, I'm probably going to take wrath from people here saying this but... MH bulbs DO NOT change much over their lifetime. Ok, so maybe there is a slight decrease in output but it is minimal. I use MH consistenly in my reseach and I have to calibrate the lamp every week; no change over the past year. Your flourescents will die overtime but not that much in 4.5 months.
Your problem seems like params OR you have some chemical warfare going on. When you say the candy cane has no colour, does it looked bleached? More importantly, is it receding? What else is hangin' out in that tank?

Well, we got a few corals doing well and then some that are not really at all.
Doing ok/well: Frogspawn Favia Red Montipora Green Digitata Green Star Polyps Green Bubble Tip Anenome (no where near any corals) Doing Poor: Candy Cane Birds Nest Hammer Coral Pulsing Xenia Colt Coral Green Montipora Cap Red Montipora Cap Thoughts? No corals are really that close to each other, most are still pretty small in size too. The Candy cane does look white, but I am inexperienced and dont know if it looks like its receding. It opens up at night no problem. Thanks for the help guys!
