Ive had people ask if it's doing that cuz the bulbs are burning out.
Lol

from the thunderstorms? remind me not to use that feature

I think it's really a case by case basis and there is no easy answer unless you have a Spectrograph. Start with considering what you currently house in your glass box atm, either way, popular consensus say to ease your system into the new lighting, watch your corals for undesired changes while increasing the intensity of the LED fixture.

The next big question comes when adding new coral to the system, this is why I’m going to use the same lighting on my frag tank as the DT, this way I can ramp the intensity up and match the photo period while acclimatizing the coral/frag to match my DT.

here are pictures.

first picture is the zoa colony under the ai sols

and this one use to be a colony but since i put the radion over that side of the tank they've all disappeared. all i've got is one here and there and theyre closed up into little balls

yikes that sucks Marko, I wonder if the radion was too much for them?

it was only 65% power

they were previously under 90% power ai

maybe another reason then? I have heard zoo's can melt sometimes

Radions are twice the power of Ai's and full spectrum.

start at 40% and work your way up over two weeks.

Under Ai's I never got any colour this is one miracle change since adding a Radion

it has now gone onto to be super dark purple:mrgreen:

the feature I like about the radions is......you can start the morning off with the red spectrum (which BTW is beneficial for you coral ) to simulate a sunrise effect, then have the spectrum change to natural sunlight during the day when your not home to see the yellow-ness, then have the color change to more of a blue in the evening when you are home to see tank.....I'll agree that the thunderstorm feature is more for the user than the reef

Before the radion, these same zoas were under the ai and open all day.

And how do you figure that 12 watts of red LEDs are beneficial to corals?

This weekend I'm going to try this out. I'm gonna have the reds on only, for the first 5 hours of the day. And I'll take a time lapse video of a zoa frag to see if it'll even react (open,close,twitch) at the red light
