OK, so I am getting the skimmer dialed in...the tank ios 2 months old, and the skimmer has been on since. I loaded my 450 with about 500lbs of dry pukani rock, another 350lbs LR in the sump..and am now feeding the Reeflo 250 with a Quiet One 3000. My issue is that I am seeing my nitrates creep higher every day! I am at about 80 for nitrates now, with only 5 tangs and a bunch of smaller fish. My thought was that spending more on a nice skimmer would mean no nitrate issues.....but here I am again seeing nitrates on the rise.
My question is: does the skimming performance differ when using a feed pump from the sump vs. fresh "dirty"
water from the overflows? Or are the nitrates a result of the dry base rock curing and becoming live? If so, wouldn't I have seen this earlier on? Any info will help!
