I am currently running my 220 with a 50 gallon sump and skimmer to match. I havent dosed anything and was wondering if this is going to be a problem for the future. My corals seem to be doing fine, params are fine ect. I have had the tank up and running for about 4months. Any concerns?? I have also posted some update pictures. This is currently half the tank I really need more rock.
