Nope Ray - no nitrates at all, my guess is running two skimmers and doing weekly water changes of 15% are the way to go. I do agree that I am overstocked though I read about people with reef tanks and lots of fish. The old school of thought was that in reef tanks you should have little to no fish but it seems with all the filtration methods avaliable it can be possible to have your cake and eat it to. Though I think after some research I am gonna skip the Angel mainly since I read it may nip at Brain Corals and Mantles - and that is no good.
I keep a ten gallon tank running under my UV
sterilozer shelf at all times with water for water changes. Using the pump from the sump I take about 10 gallons out weekly then hit the pump on the ten gallon which is connected by vinyl tubing to the 50 gallon reef and refill it. The water is run through with the main tanks' water weekly so not only does it make the amount of water greater to balance salinity - it makes water changes a snap.
Now if only I could build a robot to clean my powerheads and filters!
