I am using 2x radion and it is 8 inch above the water level running 100% , I switched to zeovit for the colour issues but it does not seems to help. I dosed b balance , cv and xtra
You are running your radion 100%??, have you acclimated your sps?? I have mine set to 55% 8" above water line and they are doing fine, when I introduce new sps, and when my radions are set to 75% to 80%, they get bleach with in a week. Thats why I turned it down to 55%. I am planning to slowly increase it 5% every 2 weeks. Radion lights are very intense when set to 100%.
The other thing is, what size is your tank?? That also makes a difference.
Good luck,
What is your depth of your tank ? How high is corrals ?
When you say the colors are stripped from the corals, are they turning brown or white? What coverage do radions give, meaning how many units do they suggest over 4' span? How long at 100% are you? Do you ramp up then down and only 100% for an hour around 2 pm?
When SPS are placed in a new tank I have learned it is normal for them to react by turning brownish and losing color. Moving them up will help, but only a little at a time.
I recently had the browning problem and moved the SPS up pretty high in my tank, I bumped up my AI sols to 85% range. I only have three units and could probably keep the SPS a little lower if I had a fourth unit. Within a few weeks now most are regaining color...pink, blue, purple, and green.
Ok, see if the bleaching has stopped or slowed down. They you can slowly up 5% a week.
