Question on BTA and new LED lights??

[Prairie Reef]

Hey all,

I think I'm being paranoid, but figure I would check in anyway to make sure I'm not missing anything.

I just installed AI Sol Super Blues on my 75 - 2 of them 12" AWL.

To let everything adjust, I started at:
10:30am - 2:30am W40, B35, R35 Ramp 240
5:30pm - 10:00pm W10, B25, R25 Ramp 240
10:00pm-Lunar, W1, B1, R1

I've had them on for 3 days now and no other corals look upset (bleaching or burning). In fact my maxi-mini's have been flat down on their rocks and appear quite happy (they are in the bottom 1/3 of the tank). I'll be moving the intensity up a little each week of course, but my question is this:

My BTA that used to spread out above the rockwork on the back wall has now withdrawn behind the rockwork in an area I can't see well. His color is good - not whitening, he is not expanded much (tentacles look a little deflated and ropey). The clown continues to be hanging in him.

As I understand, they will move to get to a happy place, right? I mean I don't need to do anything to help him? If the light it too intense he'll move? Which channel of light is most useful to the nem? White I assume.

Thanks in advance.

I would look at dimming the blues and royal blues somewhere around 6-7. Yes you dropped the white down at 5:30 but the B and RBs are still strong. What kind of lighting did you switch from?

Thanks - I'll do that.

I switched from a t5 set, individual reflectors with 5 bulbs: 3midday 6.5k, 1pure actinic and 1blue+. They were on from 2pm to 10pm roughly.

LEDs are very efficient, when I switched to LEDs (par38)band found the right height to mount (to adjust brightness), I found that the tank looked about 30% dimmer than when I had t5s. So when corals/nems are under LEDs, they don't need to open as much to get the energy they need.

Thanks sea monkey - humm... so do you think he'll ever *literally* crawl out from under his rock?!? LOL.

Seriously tho, he should manage himself and I can just acclimate the tank to the lights as I've read on so many other threads?

I did move my blues clear down for the ramp period like Matt suggested, makes sense.

Quick update - I dropped the blues, and in a bit of a risk, but taking cues from the rest of the tank, turn up the whites during the mid-day segment to 50% - everyone is happy and the nem was back in his "sheldon spot." Thanks!
