Hi there Im new

and Im in search of someone who maybe able to help and thought the hydro guys might know.

I need to grow algea under leds for a type of filter on a marine aquarium called an ATS

what im tring to find out is if algea prefer a special type of colour as there are many options.

My thoughts are to go with a vegative quad band led @ 50w as algea dosent flower (I think) so better range of blue nm then red nm would do it, quad also have white and orange, maybe orange is what it really needs but not sure what that range actually does to the plant.

people who have ATS use cfl, t5s etc in the 4000k range as they say it has a higher red spectrum in it and they get better results.they have also used 6000k and still 4000k are better.

any help in the right direction would be great...

this is an email I got from the led supplier about the range they have.

Dear Mr.Shane Grant,

Thank you for your prompt reply!

Here I send the PI of quad band 50w led grow light for you as attached file.

All of our price are in $US.

Blue light is good for vegetatives and the red light is good for flowering and budding, you can choose the ratio of the light, which have wonderful efficacy for the plant.

Vegetative(Dual-band): Red: 620~630nm / Blue: 450~465nm R/B ratio: 8:1 or 7:2

Flowering(Dual-band): Red: 660nm / Blue: 450~465nm R/B ratio: 8:1 or 7:2

Vegetative(Tri-band): Red: 620~630nm / Orange: 610~615nm / Blue: 450~465nm R/O/B ratio: 7:1:1

Flowering (Tri-band) : Red: 660nm / Orange: 610~615nm / Blue: 450~465nm R/O/B ratio: 7:1:1

Vegetative(Dual-band): Red: 620~630nm / Orange: 610~615nm / Blue: 450~465nm/White R/O/B/W ratio: 6:1:1:1

Flowering (Dual-band) : Red: 660nm / Orange: 610~615nm / Blue: 450~465nm/White R/O/B/W ratio: 6:1:1:1

Yours sincerely,

Michael
