That is the rock that was on the island , they would not let us import rock at all so we had to make due . the owner did all of the rock work and in the end it was one of the best tanks I have ever seen . these pictures are from a year ago , I cant find the new ones I have but will take more on my next trip down . we usually go down every two months to work on various projects ion the island .
we have also got rid of all of the leds we had on this tank as they were not growing coral well and would fail a lot .I had the same problem on my tank and tossed 13k worth of leds and went back to halides .
