I brought this skimmer from a fellow reefer and couldnt be happier about the purchase. I have a 180 Gallon display, 30 gallon refugium, and 20 gallon sump. I have mostly sps and 20-25 fish ranging from 1 to 5 inches. I feed 1 to 2 times daily. Skimmate shots after 5 days are shown below, enjoy!
BTW I am running this skimmer externally and it is fed my a Rio HF 20.
