how to set Mitras 6100 HV

[Monty]

This is simply not true.
Max output has nothing to do with color temperature.
And even with 6k you will have nice coral growth but the color will be different from what we like to see.

That is true
But 12k MH is different 12k LED, led is to much yellow
That same is in 14k

[Monty]

So if it looks to yellow to your eye, why do you don't set the particular channel(s) lower and the blue and whites higher?
With the lightcomposer I tried to set something what now mimics ATI's Purple Plus and Coral Plus cobo, just by plotting the light spectra in the composer.
It would be a charm to imitate any MH or T5 up to 90% if not more with an spectrometer on hand, but even so with a bit effort we can do so with try and trail in the composer.

I guess we talk about 2 different "max output"

I was talking about the "energy options": set everything there to maximum (high output, 100%, 65°C, fans 100%)! more power!

1. in the light composer you set every light channel to the maximum in the first step
2. then reduce the light channels you dislike and which are not so important for the coral growth - e.g. yellow, green, maybe reduce the warm white (4400K) and the normal red a little - leave the rest at max.

you should not reduce the LED channles which are important for the photosyntesis - like all blue, hyperviolet, cool white and hyperred!

Thx
I will try, and give answer

Sorry to hijack this old thread but what is the difference between red and hyperred ?

Matthias is saying hypered is essential for photosynthesis but in a recent thread I was told not to use any red due to nuisance algae ?

Thanks

[Matthias]

the difference is the wavelength

but in a recent thread I was told not to use any red due to nuisance algae ?

there are a lot of different opinions about algaes and the spectrum

but keep one thing in mind: plants, algaes and (most) zooxanthella are doing photosynthesis through the several types of chlorophil, carotinoid and others

[monkeyboy]

I understand they are different wavelengths, that's stating the obvious. Maybe I should have elaboarated on the question

Does hyperred penetrate deeper through the water. Do corals use hypered more than red. Do nuisance algaes use red more than hyperred.

I have brown algae on my sand bed. It's not a slime, neither a diatom as the tank is a year old. It's hard to distinguish what it is.

I'm wondering what part of my light run is fuelling the bloom ?

[Matthias]

in the light composer you can switch on "chlorophyl A+ B" and "violaxantin"

this gives you an idea what part of the spectrum is important for photosynthesis

thumb rule:

all HV, blue and white + hyperred near to 100%, the others according to your taste
