So your saying so long as no shadows (because LED are so directional) you can have as many as you want (within reason)?

I was running 2x 26hds (as you likely know from talking in chat) and I just added a 3rd which now seems to have removed mode of the shadows.

I also ready that 1 Hydra 26hd is not equivalent to half a 52hd but more like 70% of a 52? Can anyone confirm with par readings?

so without using acclimation mode, is there really no way to scale down a schedule to X%?

Pretty much yes to question 1. So pretty much within reason the most lights you can run and the highest you can run them off the water (up to about 2') the less hot spotting and better coverage you can have. As for question 2 the wattages are a misconception and have to do with power routing. The more diodes you can run in series the less total wattage per diode is required due to the effect of some energy used to power diode one passing on to diode two and so on. Someone with an electrical engineering degree can describe much better then I lol. But basically even though if you add up two hydra 26HD it is higher total wattage then 1 52HD this doesn't translate into two 26's or 4 primes putting out more photons then the 52HD. I hope hat wasn't confusing as all hell lol

If you want to run a schedule that's the same spectrum but 25% less intense just put he light in acclimation mode at 25% and move the end date out like 10 years.

Nah man all makes sense to me

So my 3x26hds should be perfect, might also explain why the LFS was saying am I crazy???

To scale down a schedule permanently, could you just simply multiply the schedule %'s by the amount you want to scale back by? So instead of 100% blue, just set it at 75%, etc? Would that pemanently give you a scaled back schedule?

Yes, should keep the same spectrum just not as bright.
Honestly just run them about 10" above the water with a 40% acclamation for 2 weeks and it will be perfectly ok.

It's not the same. After one year, the values would have ramped up. And what if I actually need to use the acclimation mode?
I think a master intensity setting would be a useful feature.

 

[Spunky Bob]

Speaking of.. that's a feature that AI needs to implement.. a way to grab ALL the set point and reduce or increase them at the same time.

Just a personal opinion here but everyone freaks over intensity of the light frying their corals when the dang sun illuminates them in the ocean. This schedule is designed to mimic the spectrum of light corals receive at 20' down and by limiting the white channels to 25% or less it eliminates the problem of frying your corals with tons of spectrum they don't use. But honestly even that might not be necessary preeminent reefers like Dave Saxby and Wazzle run many more these fixtures over the same area as the average reefer and they run all channels at 100%. What I'm getting at is once you have "enough" light it's probably the least important aspect of a thriving reef. Water quality, movement and husbandry make for stunning results not the lighting.

Also some updated tank shots! And for reference I'm running a Hydra 52 HD running the sps AB+ schedule and 48 watts worth of t5ho on a 24"x24" mixed reef.

FYI this is 3x 26HDs on my 4x2x50cm using Orcus' profile running about 10" above the water.

Cheers man.

And this is how the schedule is at time of photo.
No acclamation mode or anything.

New to the Hydras here...

Just picked up 4 of the Original Hydra 26 models for my 72" 120g. Seems like 10" above the water is a good setup? I'm getting ready to build some sort of DIY hanging rail kit for my setup. All tips welcomed! Coming from 3 of the eBay Black box lights..

If you don't mind me asking what is your intensity set at for peak times. And any numbers on the mix %? Tank looks very nice under the K your running.

Im testing a section of my 300g tank with green star polyps. I have a ai prime over it and wondered what would be a good setting to start with. Its about 22" below surface. The other polyps grow like crazy on the other side of the tank with 6 year old led lights.

GSP can pretty much take any amount of light you throw at them. But somewhere around 30%W,R,G channels and 90%RB,B,V,UV is a good place to start.
