The uv LED question

[The Alchemist]

Is there any hard evidence so far as to any benefit in having uv ( 398nm ) as apart of your led colour makeup.

Cheers

I have been looking for this too. So far, I can find no evidence. There is a 417nm chlorophyll A line, so that might be useful for coral health but I can't find any evidence of value to anything lower.

i just added 8 uv leds to my set up... ..i had a few corals that looked awesome in the store ..at home not so much ..

lets just say i found the missing link..he colors pop so much more... for that alone i recommend them.

You used actual uv (sub-400 nm) LED's?

I have the cadlights 120watt uv led pendant. My first tank but I'm getting rapid growth and color from my monti caps, spongodes, favites, and birdsnest. My softies are bright colored as well. My buddy has a MH on his tank and I'm growing stuff at the same rate.

Anyone have any idea/theory why corals could benefit from below 410nm?

I know that 420nm or pure/ true artinic really only highlights phosphorescence in corals or more specific the zooxanthellae is highlighted. It does little to encourage coral growth and I believe that only certain types of zooxanthellae are benefited by 420nm light.

Therefor perhaps under 410nm will only encourage phosphorescence

Ive just purchased a 390nm uv flash light so I guess I'll know what effect will do.

no they are 410 to 420..from rapid led

i also run a 14k mh and still have 2 t5 actinics on a 36 x 24 x24 tank..starting the conversion to led my all my bulbs are only a couple months old.so doing it over a little time..i just added 16 royal blue and the 8 uv ... the blue is to much at the moment ..i still need to get the dimmer adjusted..literally just added them over the past weekend....

sorry i cant answer the question of below 400 nm being beneficial ..but i will have a few uv on every tank i own from now on..just for what it does for the coloring in the tank..makes the fluorescents in the tank incredible

If it exists in nature, my assumption would be that it is beneficial. Most lifeforms evolve to need everything that is in their environment to a certain degree. Removing something like UV may not seem to hurt them, but I suspect something in the animal requires it.

You know what happens when you assume.....
