I have had a few issues with my 3 year old reef. I'd say 90% of the coral are fine but I've seen some RTN of random coral starting this summer. I initially thought it could be low Nitrate levels, but I'm not convinced that's all so I ordered a ICP test. I'm using Kent salt and have since the tank was started. I was doing 50g (of 700 total water volume) of water change weekly until I started to seemly have more issues after the water change. Now I do maybe half that. I noticed Boron is low, but it was in a Triton test I did a year back so I don't think this is an issue. The one I'm worried about is Molybdenum being zero as it had some level with a previous Triton test. Could this be completely depleted by my large coral load? The tank is absolutely packed with coral and macro algae in an attached fuge. Is this something I can dose safely despite not being able to test on my own? Anything else I should be concerned about with these ICP results?
