King, that algae on the sand is cyano. It s**ks to get rid of. Increase your flow in the area you are getting it and lower your phosphates. If you are still getting it, use marcyn tablets at half the dose. It will cover and choke you coral. I had it bad once, I still get it, but work to get rid of it fast.
The coral banded is sweet! Fantastic color, and great pic!
The most I have ever spent for a coral was $50 and that was for my goni and lobo hantai, the lobo died within 3 days, and the goni is not doing to well, it was one of first and I have had it longer than I should have. I buy frags mostly, I love watching them grow. I take a picture ever other month and compare.
