cold cathode tube moonlight

[rohnds]

I have friend of mine that doesn't want his 12" cold cathode tube moonlight. It give off a brilliant blue light.

What are the advantage of these; besides the asthetic value, longer viewing time and transition to the total blackness.

Does these produce the same blue light spectrum that might benefit my corals?

I had two 12" tubes in my 15gal tank, also got them in my computer.

I dont think they would give anything other that a blue glow.. not sure though

They are supposed to give the tank a night time feel. It is supposed to increase coral spawning, but that is just what I have read.

Would excess of this light type cause algae bloom.

i dont think so, since its not within the natural sunlight range.

I thought photosynthesis (Chlorophyll) use the visible light spectrum (except green)? That’s why I am a little skeptic.
For those that use of these blue light cathodes, do you have it turned on during the entire night? If not, how long?

Is there anyone out here that uses a blue cold cathode? Is so, has it anyway resulted in algae bloom? And how long is it turned on per day?

I used 2x 12inch blue cold cathodes on my 15gal tank for about 2 months before i burn the transformer out and i didnt have any algae blooms.

had them on from 11oclock at night until about 3am

Sorry. Never mind, I found the answer.
