The tank is going on 7 weeks. I am running ROWA in a reactor since day 1. Fresh Chemipure elite in both filter socks. My tank is 200 gallons plus sump. The sump has a fuge with cheato. The light for the fuge is on only overnight. Im currently using a Bubble Magnus Curve 9 skimmer, but I dosed with prazipro for flukes a few weeks ago and was not able to use the skimmer because it kept overflowing. I just tested with red sea test kits and my nitrates are undetectable and phosphates with a hanna is .07.
