Optimal Radion settings?

Breakthecycle2 · Aug 29, 2015

Looking for suggestions. I am having a real problem with SPS. I lost all my one frag. All turned white...could be a seperate issue, but I want to get an optimal setting. Right now, I have the overall intensity of 50%. Whites max out at 38% for two or three hours. Blues are around 80%, red and green maybe 5-10%. UV 85%. My tank is 72x28x22. Lights are on an RMS mount across the tank. They are about 10" of the tank. I am currently running three of them. One of my lobos also started to bleach. The rock work goes (at the highest) to about 18" inside the tank. SPS are mounted around the height. LPS are mid to sandbed.

Most likely your lights are set to high. IF this are the radion pro they are extremely powerful. I personally am using apex to control them so its a little different. I would recommend getting a par meter from your local reefer group and find out what your par ratings are during each light cycle

These are not pro's. They are regular G3's. I am currently running them off of the reeflink.

I would still get par meter. When you have low light things don't bleach they usually don't grow. High light usually bakes the stuff aka bleaching. Just my 2 cents I am by far not an expert.

OK, hopefully someone else can give me some setting to try. I appreciate your input.

My first question would be, did you use the acclimation program when you set up the Radions?

Too much UV back it down

Are you using a preset program?
If not I would.

How long of a acclimation period did you use?

I am using the radiant program, but I adjusted some settings to lower them. I used a two week acclimation period.

So, your total intensity is at 50%, you said. I have mine at 65% for a mixed softy/LPS. Corals were acclimated for 2 weeks, maybe a little short, but it also depends on what lighting was used previously. So I would go out on a limb and say it may not be the lights that's creating the bleaching.

Might be other factors, like salt, dosing, age of the tank, or a combination of things.
Wish I had more for you.
