black light?

Currently running a new t5ho with moonlights (8blue leds) my question is i have some lighting fixtures i can fit on the top still that take standard tube bulbs is it possible to do a black light just to give corals that pop? i know the coral will not benifit from this in anyway just for looks but will it hurt anything or has anyone tried/done this?? I saw a you tube vid and it looked pretty sweet.. any input is great.. thanks

 

I think it would only work with all the other lights off...I think your other lights will completely wash out the black light otherwise.

 

well i wasnt planning on using it during the day.. just when i have my 8 blue leds on..

 

I'm not to sure on the exact type of algae, but I had a very simular problem once on a 36 gallon I had when I had improper lighting for a fresh water tank. I had 18,000K bulbs which has a very blue tint to it. After two or three weeks it seamed like everything but the fish were covered in algae and the water had a green tint.

If you have had a blue LEDs one for a while each day, and they were bright enough, I'd guess that was the cause of your algae.

For me, I just replaced the bulbs, cut back on hte lighting for two weeks, did larger daily water changes for a week, and manually clean off as much algae as I could which fixed the problem

Just a guess tho based on the blue LEDs that have been used

 

What are you talking about? He's asking about using a black light. Nothing about algae. You must have your threads mixed up

 

i read that it can really harm fish. i think blindness
