AI Hydra Settings Thread

[limavet1]

I have gone ahead and updated the SPS AB+ files to the ones I have been using for the past few weeks. I tweaked the profiles a bit to reduce the max intensity photoperiod but added high noon rapid shifting peaks to more closely mimic the suns natural PAR fluctuations at mid day. If anyone is interested a reefer scientist named Dana Riddle has some fantastic research out there on coral coloration and the intensity of the light being produced by the sun. His studies are what I based the profile changes off of. I am using the low power schedule in conjunction with two T5HO (1 ATI Coral Plus & 1 Giesemann Tropic) on my SCA 50 and the High Power schedule on my 17 gallon anemone cube. If anyone is interested I can link Riddles articles and explain the why in more detail. Below is a screenshot of the new profiles and a link to where they can be found. Happy reefing! https://1drv.ms/f/s!Akco_cmvvLNrgZdidaM1bosnUqv21g

Orcus, may I use high power schedulle on my mixed tank with sps and lps corals? My hydras are 26hd 24 awl. Tks

Should be just fine just be sure to acclimate slowly.

How do you save a profile if using iPhone software to program the light?

Okay so it's a bit of a pain but you must first copy the link I posted and paste it into google chrome browser. For some reason safari is a pain with opening the one drive links. Once in the one drive web view click on the profile you wish to download and follow the pictures below. Once you download and open the file in myAI you will have to go to the myAI app for the remaining steps. Please let me know if you have any more trouble and i will try to help some more. Happy reefing!!

I want to download and save the profile from my light using iPhone. Not the other way around.

I'd like to see the article please.

Just a bit of light reading to get the brain going on a Sunday morning [emoji23]. The gist of the material is a verification of what most of us have observed as aquarists for years. 1. Blue light is very important, 2. Red light is potentially bad for coral growth BUT is required to some extent for optimal coloration, 3. the output of light intensity by the sun varies throughout the day and is interrupted many times by cloudcover, wave action, etc throughout the day. It is all very interesting stuff and with my profiles I am attempting to recreate corals natural envirionment as best as I can in a 50 gallon box.

On #3, I don't think the simulation in your AI profile is realistic nor necessary. Happy reefing.

Thanks for your expertise !


I just set up 3 Hydra 26's and can't totally figure out how to get such complex programming. Your preset is now locked and loaded on my system!

Explain then how a constant blast of light at the same intensity for 8-12 hrs is? I don't mind disagreeing with my points or the premise of my profile, but it bothers me when people say "nope your wrong" and offer nothing in return... The below graph represents readings that were actually taken on a typical day on a reef in Hawaii. I can not simulate down to the second as AI's software has limitations. I do feel however that my program is a better approximation of the natural reef environment then the standard straight line profile. Finally the research done by Dana Riddle, Dave Saxby and others on the delicate interplay between spectrum, photosynthesis rate and chromatoprotien formation begs for us to dive deeper into what these lights can do. My personal results indicate that if I have two corals under the lights one with a straight line split 25/90 Blue/White and another one like my AB+ with respiration peaks I am able to keep light sensitive corals from retracting and my anemone from expanding to the size of a cookie sheet. This is not the case under the straight line profile ime...

Even though I'm not computer savy, I created a similar program & it's working great! Thanks for the idea.

You do realize the graph you showed was measured at 2" under water right?

 

[dz6t]

You also should learned how the graph was generated and time points taken and standard deviation.
The up and down of the data points were caused by the way a instrument was used to measured PAR, not because of the sun was behave like that.

Yes I do but you do realize light intensity fluctuates just as much if not more 10 feet underwater? I'm sorry if my lack of understanding the marine environment is beneath you I only hold a BS in Marine Science...

"You also should learned" nice grammar! I will take the advice of someone who is educated over those not!

Thank you it is much appreciated. I post on here in an attempt to stir thoughtful debate and to hopefully help others along the way. I never mind an opposing opinion, I just demand and want the community to demand thoughtful educated responses.

Mind you that I have a PhD but that is not the point. And I run a coral farm too.

The point is that the "jagged edges" in the graph were effected by how the data points were taken. Also at 2 inch under water, surface ripples could cause the data points to jump around too.
English is not my first language but I guess education is not part of the problem.

Thank you very much.
Another point I want to bring up is that if you use a wave maker, due to the surface movement, AI hydra led pucks (like the sun, a point source light) can make the PAR values go up and down (just like the graph shown), without actually program the led to do it.

They were taken in a tide pool on a day in which it was exposed with no inbound water for the duration of the study in order to minimize the affects of surface agitation. If anything par banding would be magnified at depth due to the lensing effect water has on light. I don't mind you disagreeing I just want to be provided with hard data as to why I am wrong. I do not accept just because, you as a scientist yourself should understand my never ending yearning to be educated vs. told.

Yup, who's educated now?
