BTA and lighting question

[Coralgurl]

In my experience, 2 t5 lights will not be enough for any coral. I had a similar set up and when I added coral, they would not open, almost lost them. Supplement with LEDs or add more t5's.

I've got three monti caps, a birds nest frag, some zoas/plays, a torch, leptoseris, and a favia, and they are all doing fine under the T5s. Colours are good and they are opening up and growing really nicely. Maybe these are stronger than the T5's you had?

They are the stock T5 10K 50/50 actinic PC fluorescents that come with the RSMs.

I will be supplementing with LEDs though, as you suggested, to get some colour to pop as th T5s are quite white, and it will help add some more light which will make my birds nest happier.

Could be you have better lights than what I had for sure. When I added the LEDs, plus used better t5's, I got amazing growth from all my corals, including a rbta. So you should be fine.

When you got your new T5s and LEDs where did your RBTA like to sit in your tank?

[Coralgurl]

He sat lower to the bottom. Was an 18" deep tank, lights were 6" above. When I moved it to the 180 gl under radions, he is higher up, middle of the tank. When I got him, he was maybe 4" across fully expanded. He is now well over a foot big and still growing. I have another rbta that has split, both are at the bottom of the tank.

if lights not enough for a BTA could you supplement with direct feeding?
