Is 128 watt per gallan too much lighting???

[vmichael]

I'm thinking of having the following custom made canopy for my 55 gal reef tank.

tank is 24" deep 48" wide and currently has 2- 65 watt 10, 000K Power Compact and 2- 65 watt Power Compact actinics blue total 256 watts


The question is:
Is it possible to have too much light in the tank?

Lighting specs are as follows:
48"W X 11" x 4" H

2- 250 watt HQ 20,000K Metal Halides
2- 65 watt Power Compact Actinic bulbs
2- 36 Watt PC 10,000K Power Compact bulbs
2- 4 inch fans

Total wattage 702 watts

This would be 12.8 watts per gallon for my 55 gallon tank.

I'm not taking into account water displacement from the live rock (aprox 115 lbs.)

Anybody have an idea?

your comments are greatly appreciated!

Nope, if you can handle the added heat there is no such thing as to much light. This is assuming your corals are acclimated to the lighting properly.

I had pretty much the same on my old 55g, only I used 4x110w vho's instead of pc's, so it was 2x250w iwasaki and 4x110w vho, 3 actinic and 1 day.

That much light is not really needed, but let us know how it works out. It will be interesting.

I used to have over 1000W over a 60 gal, and I can tell you that I did not see the growth rate in portion to the wattage I put in. Obviously, there are some other limiting factors, such as calcium and others.
