Good even my fellow reefers, I need your advice and suggestions. I just recently modified my 120 Gallons to a dual Herbie Overflow. I have achieved complete silence on both main drain standpipes with a small trickle in both emergency standpipes. I currently own a Eshopps ADV 200 Refugium Sump-3rd Generation. The issue now is the return pump (Apex COR 20 running at 40%) chamber waterline is passed the manufacturer stated line, almost double the amount of water that is supposed to be in it; which sets my ATO alarm off constantly. Also, the Skimmer (Skimz SM 161) chamber waterline hovers either at or below the recommended minimum 7 inches of water. I want to raise/increase the water in the Skimmer Chamber, but lower the waterline in the return chamber. How can I achieve this goal? See photos. Your help is greatly appreciated
