I have a 420 liter tank with a Ceato refuge. I have many fish that are heavily fed and LPS, SPS and a few soft corals. My tank is close to 3 years old. I dose the TM ABC Balling system and I mix the K and A elements into the A and B respectivly. So It adds to about 60 ml of ABC and 3-4 ml of the A & K daily. I do not do water changes (almost 2 years). I dose 3 ml Elimi NP daily and one spoon Reef actif twice a week. My corals are looking great (apart from those niblled by my CBB). I run a powerfull skimmer, and GFO and GAC reactors.
My question is: Is there a trace element that I should worry about to accumulate to toxic levels long term?
Thanks
