In terms of SE and DE halide, JohnK is right. The center bubble inside the bulbs are the same for both DE and SE. If you do a quantum count using the big ball shape meter that light manufactures use, the total photon counts are similar.
Hmm. She doesn’t nip at polyps or inverts but she doesn’t get along with other females very well. Probably should have introduced her to the tank last.
At least she’s easy to catch. Unlike that yellow tang in my 90. It’s actually harassing clown fish. Bad attitude.
He’s going in the frag tank for a while when I break down the 90 and put everything in the 180. I’ll put a few other tangs in the 180, let them get good and established and then see how tuff that yellow tang really is.
Nice spread. I'd look at like what would happen if a massive wave deposited the rocks in the tank?? Level and plumb rarely occurs naturally. That tank is beast mode, can't wait to see what you do with it.. aside from overstocking humans...
