I'm running two 65 watt 10,000K and two 65 watt True Actinic 03 Blue straight pin base compact fluorescent lamps. I mainly have zooanthids, polyps, mushrooms and frog spawn. What would be the first indication they are not recieving the light they need? Do I even need to worry about light with this setup?
 
IMO, yes, you should pursue new lighting. What size tank and where are your corals located? I had the same lighting at first and it made everything shrink until I got a t5 set-up. I'm not saying they won't live but they will not grow or show full potential.
 
Hmmm.. generally zoanthids won't open up all the way.. or their base will "stretch", or even start detaching if they aren't getting enough light.

For the frogspawn I would watch for bleaching of the tissue.

Look for browning, too. Many corals will lose their color and turn brown if they aren't getting enough light. With a tank that deep, you might want to think about upgrading your lighting, especially if you want to consider keeping other types of coral in the future.
 
You have inadequate lighting-IMO.

Using the old, but still useful, guidline of watts per gallon-you are at 1.8W/gal. A good rule of thumb would be to look for at least 5W/gal. (all you lighting experts, please hush for a minute;). LED's are probably about 50-70 percent of that (2-4 W/gal.). The reasons are very technical, but I'll explain it simply. Most lights shine in all directions. LED's are highly directional (think focused here/so more efficient).

The best way is to define what you want to keep (ie-soft coral, LPS and/or SPS, and then decide which light will work best for YOU. The W/gal rule dictates that you should be somewhere above approximately 5W/gal. However, education is key in this hobby, so I will spare the dialog and suggest some reading instead. I could bore you into submission by citing what I have learned about lighting, but it's not about me. It's about you, and your passion for this hobby, and your specimens. So Aquarist, go enlighten</em> yourself!

(Sorry for the clumsy pun, and happy reading)

FWIW- I do not agree with <u>everything</u> the author on that site write's, but it IS the most comprehensive single resource on aquarium lighting, that I have found-

PS-in the end it will come down to T-5 flourescent, metal halide or possibly the newer LED's. After reading up on this, feel free to ask questions.
 
PSS-

PAR (photosynthetically active radiation) is what is important to corals. Sometimes this will be discussed as PUR (photosynthetically useful radiation).

PAR- is based on the active spectrums of all photosyntheic pigments (ie-what is possible).

PUR- is based on those pigments a given organism actually posesses and wavelenghts it can actually absorb/use (ie-what is probable).

I was hoping you'd chime in! Anytime someone asks about lighting, I think of the threads you have posted in the past. Unfortunately, I can't seem to find the one I'm looking for...

I'll keep looking.
