Just put it on acclimation mode 30% for 1 month or so. I have a prime hd running the 24" profile on my 15" deep anemone cube.

By the way I love those lagoon tanks the dimensions are perfect. It would make a great clown and haddoni carpet nem tank.

Quality of the tank is amazing. I updated the factory return pump to a sicce for more flow. Using the Hydra 26hd on it with bracket looks great

Looks great! Can't wait to see it up and running

ok, finally got my hydra 52 hd. going to use it on a 24x24x19 tank with mostly sps.

is the aip for sps the AB+12awl and AB+24awl found in the onedrive link a few pages back?

is there any write up or a little bit more detailed description on what the aip files are doing? Like why does the intensity go up and down every 20 minutes?

thanks.

It describes the SPS AB+ schedule.
It does not contain any of that up and down every twenty minutes intensity change. Was that added randomly? What is the rationale behind that?

Yes that is the article/study by WWC and Ecotech that I based the AB+ schedule off of. I then built upon that and added what are called respiration peaks to the schedule which is essentially simulated cloud cover. Out in the real world corals do not receive 12 hrs a day of sun uninterrupted 365 days a year. Clouds often pass over providing a temporary reprieve from the intense sunshine. These periods of rest allow for periods throughout the day for the coral to divert resources to use the glucose produced during photosynthesis to make ATP during daylight hours. With constant intense lighting with no breaks you can theoretically hit a wall or photo-inhibition state where the coral has no more room to store glucose and photosynthesis will cease all together. The study you cited above vaguely touches on this by stating they reduced the amount of time they run their lights after they switched to LED lighting. The reason they ran into a wall and had to reduce the photoperiod is because of the way LED's produce light in specific radiation bands. Take Cree 450nm diodes for instance, they only produce light at the 450nm wavelength and nothing else. Exciting zooxanthelli in such specific high value bands of radiation is great because nothing is wasted but is bad because nothing is wasted. Thus the respiration peaks are added in an attempt to circumvent this limitation and allow for a full 12 hr photoperiod to maximize photosynthetic potential/growth. I hope that answers your question.

AI hydra52 setup

AI hydra52 setup

I'm curious about anyone running a mixed reef tank with the Hydra 52's. I have 8x AI Hydra 52's and 12x25w t5's on linear actuators. I have had the tank setup for nearly two years now and have never managed to get the lights above 20%. I haven't seen very good growth at the current levels. I have them positioned about 15-20" above the tank. If anyone else is running them on a similar setup I would love to hear about the results.

I wonder if the same principal can be applied to Radions? I have set the gen 4 Radions on my big tank to simulate the peaks like the Hhydras. Let's see how things work out.

I wouldn't see why not it will just take you and hr or two to sit down and add the points. The diodes used in the two lights are so similar you can basically port the values over and you should be good to go.

Yes thank you, that answers my question.

So what does the "weather" feature do? Doesn't that add cloud activity? And more randomly?

Yes and stupid lighting strikes... When I first bought the lights I turned that feature on and thought I had a ghost in my house until I figured out it was the light [emoji23]. Also, it dims the light way too much ime.

[d0ughb0y]

is there a way to view the power consumption in auto mode while schedule is runnng?

Also, for the AB+ 12awl, if I want to reduce the intensity, is there like a master intensity control that can lower the value by say 30%? or do I have to edit each point one by one and reduce the values of each of the seven channels?

also, anyone knows how the checksum is calculated in the aip/xml file?
I see the intensity of 1% is a value of 12, and it still seems bright and want to test setting it to a value of 1.

I am also trying to figure out the web interface api.
for instance, if you enter this on your webrowser

http://(your hydra ip)/api/colors

you get a response that looks like this
{"deep_red":0,"uv":0,"violet":0,"cool_white":0,"green":0,"blue":0,"royal":11,"response_code":0}

I suspect the intensity value is 10bit, so max value is 1023, although if you set a color to 100%, it shows as 999 when you run the query.

thanks

I did a google search, and see that on their old controller (maybe for SOL?), the weather function can disable lightning effect. I wonder why they removed that option. I'll email their support and ask if they can restore that option in their next firmware update.

All LPS settings

All LPS settings

I have a Hydra 26 HD over a Reefer 170 at 12" AWL. The tank is 100% LPS and I'm wondering what an appropriate lighting program would be. I've tried the AB+ settings, but some of the brains don't seem to respond well and have lost a bit of color. I notice that my LFS tends to have much dimmer LED lighting over their LPS, so should I just reduce the intensity of the AB+ settings? Thanks for your input!

Did you acclimate at all or just run it full bore? If not this schedule is probably much more intense then a prior schedule you were using so definitely acclimate at 30-40% for 60-90 days. Everyone always forgets that the corals we grow have the sun as their light source in their native environment. Thus with a slow acclimation 99% of corals can be kept under even the most intense lighting. Finally, never go off of how a lfs runs their lights. What you are seeing when your shopping are settings designed to sell. 99% of lfs run much more intense lighting for 3-4 hrs before the open then once open they turn off almost all white channels and run a blue dominant setting for the remainder of the day.

I have 3 Hydra 52HDs over a 4' long tank (48L x 28W x 24H), with the lights positioned 12" over the water line. I started using the AB+ 12AWL program but was wondering with 3 fixtures over the tank, should I scale back the peak numbers to account for it?

How many fixtures per foot is everyone using? Should I just be running 2 fixtures over a 4' long tank with this program?

I do have access to a par meter from a LFS, but wanted to get other people's experience with this program and number of units first before adding more SPS.

No I would say if anything you have too few fixtures due to the width of the tank. 48x28 is a huge area. At one point I was successfully running a 52hd and two prime HD's over a 24"x24" cube and if I wanted to stick 100% with led I would have needed two 52hds once sps really started to grow in. With leds it's all about angles, corals can adjust to pretty much any amount of par we can provide if given enough time.
