Hi
thanks for the response.
all the test I have done are where they should be (Sorry if that seams vague I don’t have them to hand).
the Duncan is at the bottom of the tank in a slightly shaded area so is not getting to much flow and when I feed Reef-Roids it eats happily But in general just looks bloated.
the tank was set up at the start of the year but everything was transferred over from the old tank that had been running for 2 years as I upgraded. all the coral, rock, sand and a large percentage of the water was added at the time and the light is the same. I’m running the ai-prime hd. All my other corals are doing fine even my hammer. It’s just the 2 Duncan’s that don’t seam happy.
