G3 Radion Pro

With the Tir 120 lenses it spreads 36x36. With the 120 degree lenses how deep can you expect them to effectively light a mixed reef with softies, lps, and sps?

Hampmp,

Our Wide Angle TIR Lenses, work best on aquariums 24 inches deep or less.

Is that assuming the light is 9" above water level? I have the g3 with the 120 lense. Only had for 2 weeks... Trying to figure them out... At 45% the tank looks dim.... I'm afraid to go higher because of bleaching

Sps are ok, zoanthids towards top are stretching
Challace sat bottom are bleached

So I'm totally confused

Running radiant color mode

930am to 9

That is correct. I would recommend enabling acclimation mode to help give your corals adjust.

My tank is 18" deep with a 4-5" sand bed. How high do you think these should be off the water for optimum spread over a 48" long tank? I have 2 radion gen3 pro's now that are about 12" off the water.

This is a unfortunate down side to LEDs. Many tanks look dim and people crank them up. I am in the same boat as you with the lights 12" above the water I could not have the lights higher then 45%. I have since raised my lights to 17" off the water and max out at 80%. This gave the lights a more appealing brighter appearance but not a t5 or halide type brightness. I have the wide angle lenses and it does waste some light illuminating the room.

 

[Twostepper4041]

I'm wondering if I go back to the normal lenses, and increase the height, if I can run it brighter

 

[Ajskennels]

zoanthids stretching at the top? thats strange, this usually means they need more light

If I blast them at 75+ percent I can get away with 27 inches right?

 

[Twostepper4041]

How could they possibly need more light when I'm bleaching challace a that are in the sandbed.... That's the strange part

just the change in lighting alone can cause bleaching, but for chalices or lps in general i dont think they require nearly the light that every one throws on them, Jason fox posted on another forum from 1 of his dives where he finds chaliced in very deep water and said " we are burning our lps with to much light", i dont know much about chalices because i dont keep many, the ones i do keep are on the sand in my 105 that is 21" deep and my 3 gen 2's are 14" from the water surface running radiant color ( 6:00am to 10:30pm) at a max intensity of 40%, no bleaching and very vibrant colors, but in my experiences and many many others when zoas are stretching they are trying to get closer to the light

P.S. are you run the acclimation setting?

 

[Twostepper4041]

Not running acclimation because I was coming from 2 led hydras. I had the hydras turned up pretty high, so I figured running overall brightness at 45% is way less than the hydras

 

[Ajskennels]

hydras or hydra 52's? the radion pro's have more than double the leds than the hydras, even with the wide angle lens its more light, that still dosent explain the zoas stretching

 

[Twostepper4041]

Normal hydras

 

[Twostepper4041]

Could they be stretching to get away from the light? Although that does not seem to be the case. They are growing away from rocks and towards the middle of the tank where the light is dominate

 

[Twostepper4041]

Huge question... My lights start ramping at 930 am using radiant color, then moonlight at 930pm

Is my photo period too short?

 

[ponda]

my zoas use to stretch until i got my first radions(g2)...... the growth is crazy!

 

[Twostepper4041]

I'm seeing significant color in my lps.... Softies are kinda faded, but lps... Wow

How did you go with this problem. My chalices are doing the same thing. Did you keep your lights at 17" above the water?

Anyone using Radion G3's and the Apex system and have a config they can share. I have a 300DD reef, getting better results out of my T5's so I think I need to re adjust my radions which are running at 25%. I was @ 40 and was getting bleaching.
