Do yourself a favor and monitor nitrates and phosphates closely. The RSK300 skimmer works great almost to great and stripped my tank of all nutrients. Both nitrates and phosphates hit zero. I had an ugly case of dinos (i think i just beat) I battled for 4 months...
Are dinos the rust colored algae, that seems to be like dust on everything? Cause I have the same tank and skimmer I think...and my tank is a nightmare.
