Hi, guys! I need your advise. I bought used AquaC Urchin skimmer with Rio 1400 pump couple weeks ago. I keep it in the sump. The problem is that the skimmer produces a lot of water (full cup every 2 hours) and I don't see any waste, the water is light green. Right now excess water just goes back in the sump through the drain ( I can't top off 2-3 gallons of water every day!). I tried to adjust cup level lower or higher, but it does nothing. Any opinion would be appreciated.
