polarbear Posted April 29, 2011 Share Posted April 29, 2011 So since I moved everything into my new 90 gallon tank, my green BTA's have not came out while the lights are on. Even when the lights are off they seem to hide under the rocks. One is all the way at the bottom under a rock edge and is touching the sand. Should I be worried about them not coming out? The 8 T5 lights that I am running now are a lot brighter then the 150 MH bulb they use to be under. I didnt know if I should move them around especially the one that is touching the sand. Please advise on what I should do if anything. Thanks everyone. Also here is a picture of the tank. I love it. Quote Link to comment Share on other sites More sharing options...
Wildman926 Posted April 29, 2011 Share Posted April 29, 2011 You should back off of your lighting, and then greadually add your lighting. They are trying to tell you that the change is not making them happy. Quote Link to comment Share on other sites More sharing options...

They are trying to tell you that the change is not making them happy. This is good advice, as this also applies for the rest of your corals. I didn't do that when I moved from my 24g with PC lights to my 75g with MH lights. I lost a lot of my corals. Quote Link to comment Share on other sites More sharing options...
JamesL Posted April 29, 2011 Share Posted April 29, 2011 Plus, I would let the anemone find it's own happy place. Besides the light changing, the flow patterns also changed, so it will probably move to a different spot it finds more favorable. Quote Link to comment Share on other sites More sharing options...
polarbear Posted April 29, 2011 Author Share Posted April 29, 2011 I'll cut back on light time. Maybe 3 or 4 hours a day. As for the rest of the corals, everything is doing fine. Should I cut back on time the light is no a day or number of lights on at the same time? Quote Link to comment Share on other sites More sharing options...
Wildman926 Posted April 29, 2011 Share Posted April 29, 2011 I would keep the same amount of time, just remove some bulbs. Quote Link to comment Share on other sites More sharing options...
polarbear Posted April 29, 2011 Author Share Posted April 29, 2011 Cool. I'll try that. Maybe go down to 2 whites and 2 blues. Will cutting back on the lights cause hair alage? Quote Link to comment Share on other sites More sharing options...
JamesL Posted May 1, 2011 Share Posted May 1, 2011 Hair algae feeds on light and excessive nutrients in the tank. So less light won't cause an outbreak of it. Quote Link to comment Share on other sites More sharing options...
mFrame Posted May 2, 2011 Share Posted May 2, 2011 As others have said, BTAs will move to where they are happy so don't try to move them yourself. I wouldn't remove bulbs, I would leave them all in and cut back the time. Start with a about 3 hours and add back an hour every 4 or 5 days until you're back to 8. Also monitor the temperature, with that your change in tank and lighting the temp could be higher. BTAs will lose their color when they get consistently too hot or too much light.
