[Piper27]

Mr Pluto your leds are only at max power for 1 hour?

 

[mr. pluto]

@ TrueBlackPerc : (2) Reef breeders photons 16 (1) Ocean revive 2060 all with 90 degree optics.
@ Piper, only blue channel 100% for 1 hr. than ramp down

Well......you do understand that for the last couple of decades we've all gone through countless color combinations of MH and T5s trying to replicate the color spectrum that's pleasing to the eye and grows corals ?

Color of the light has a significant affect on growth. In the ocean the entire red end of the spectrum has been absorbed by 30 feet, 32 feet in freshwater.

So are you growing corals that are from shallow water, deep water or somewhere in between ?

Or are your corals aquaculture /matriculate specimens that have been adapted to light not typical of their natural environment ?

But then we are way off topic.

What the A360WE in conjunction with a controller offers is the ability to run 20K in the morning, ramp up to 10K for a couple of hours of mid-day sun and ramp back down to 20K at dusk. With an Apex I do this using the season table so each day is different.

And Kessil will have a $99 controller in a few months for the A360WE.

FWIW, Red is extinguished by 3.3 feet.

My LED run at a couple of different power levels, but basically it goes like so.

(% is portion of max setting for each color group)
2 hour ramp from 0-80%
3 hour ramp from 80-100%
3.5 hour at 100%
3 hour ramp from 100-80%
2 hours ramp from 80-0%

Are you referring to your LEDs over your aquarium or the sun over the ocean ?

You can find the correct information here and even here.

You can find the correct information here and even here.

I'm referring to tanning bed over small body of water.

Hi! I figured I'd use this thread to post my information. I have a new tank, and I have some SPS inhabitants. Please let me know if I am doing something wrong, or if you see something that needs work. Thanks!!

Tank - Innovative Marine Nuvo 16

Height of the light from the water - 4" Above water surface.


Angle of light distribution -i.e. wide or spot - Wide, Kessil A350W.


Settings for color and intensity of the light(s) - 25% Blue, 60% White

Depth of the coral in the tank - SPS located in upper 50% of the water depth, central 50% of tank width.

Water clarity - i.e. using carbon or not, frequency of water changes, skimmer - Carbon, no skimmer, weekly 2g water changes.

Type of coral - Plating and encrusting montipora

Frags or colonies - Both

pH - 8.1

Alkalinity - 9.2dKh

Calcium - 420

Magnesium - 1380

Are you feeding your corals - Oyster feast

Circulation - >50x via 357gph dual nozzle return + MP10

Temp of tank and light's effect on temp - Avg 79.2 (swing 78.9 to 79.5) Kessil has no effect on temp

Thanks again!

It all looks good but why just Monties ?

You can grow any SPS you like with that set up.

Personally I would change the balance of the light to just about the opposite. 70 % channel 1, that's all your actinic and blue, and dial back channel 2 until you like the look and then watch for good growth. Maybe 30% white to start.

You'll be closer to a 15K/20K kind of light source with that balance.
