AI HYDRA Settings

[Jidan]

Anyone using hydra 26? What settings do u use? Im using a 20 by 20 by 20 tank. This is my current settings i got online. Is it too intense? Too many settings im confused.

The setting you can use will also depends on what types of coral you are keeping, height where you hang or mount your light, tank height and coral placement ect..

The setting that you shared is the popular radion A+B setting which is bringing out growth and colors for mainly SPS corals, which could be too strong if you are keeping lps.

I just lowered the settings by 40%, im mainly keeping lps and soft corals. No sps. Height of light from water surface is 12inches. Will it still be fine?

Also my max intensity for the blues are 60%. Im afraid i might burn the corals, im keeping hammers, duncans, zoas atm only. Sorry for the noob question!

I'm running Hydras on my tank. IMO, its always better to be dimmer than too bright.

Generally, UV, V, G, R, CW can be lowered by about 40-50% from your current levels.

You can keep the RY & B in the 80% range - to allow the colors to pop.

I would keep the lighting hours short too. Maybe ramp up/down 1hr each. Strong lighting hours around 5-6hrs for a start.

 

The tell tale signs of insufficient light for zoa is their neck will stretch out very long.

Hammers & Duncans can do very well in extremely low & shaded light.

I tried reading up online and im confused at the part where they say corals usually only take in RY, B and W? So if they are too bright i might burn the corals. Whats your intensity at peak? Mind sharing your graph?

To drive photosynthesis you want to target wavelengths of 430,450 and 660nm, for chlorophyll A and C1 in corals. So you only actually need blue lights, white exists more for aesthetic appeal. 

660nm is red. Red has been shown experimentally to have a negative effect on corals photophysiology. Is postulated that corals regulate zooxanthellae populaion according to intensity of red light, like an intensity gauge.

As for intensity, a par of 100-150 micromol/m^2  for most lps is a good target and higher for SPS. 

Granted Par is actually pretty useless to us withouth a spectral reading. For the same power, par is also biased towards higher wavelengths. You should only note the intensity of the key wavelengths. So while kessil may give shitty par readings(esp given the price) compared to radion, it is perfectly engineered to drive photosynthesis in corals for the given power.

Note the measurement unit is micromol of photons per unit area. 

You can find spectral readings and Par numbers on Bulk reef supply youtube channel. Par increases linearly with respect to power(given the same spectral emission), so if you using a hydra26, multiplying a prime reading by two will is a good rough estimate.

The study on red light, for your reference.

Anyway, for your tank size, given that you do not keep any sps, can just run all the blue channels at 50% and tweak green and coolwhite according to what you find aesthetically appealing.

Can slowly ramp up UV too. Even at 100% AI doesnt produce much UV at all.

U can follow BRSTV settings. Fwd to 10:51. It is based off ecotech's radion AB+ par settings. Set it and forget it. Loved the improvement and big thanks to BRSTV creating and sharing these settings! I see a improvement in some of my hard to colour sps despite my high bioload.

Thabks hedge! So basically i just run blues and the rest are just personal preference. Is violet considered part of blue?

Well violet isnt blue, at least not in the ostensive sense. It should be around 420nm, which fits into the absorption peak of chlorophyll A.

You can keep it in line with the blue but you might get a purplish tank which may not appeal to you. So personal aesthetic appeal does play a large role.

I just watch the video and they only show the spectrum leh, unless im watching a different video hmmm

Okay! Ive lowered my intensity and will see how my corals respond hehe. Thanks bro

The settings are shown on the video after 10:51.
