Update * I've been ruining the skimmer to break it in and I'm having problems dialing it in. My tank details:
150g display / 50 gal sump (working level) and water line is at 8.5 inches which is within the optimum water level suggested by the manufacturer. Skimmer is Reef Octopus xs250. Still in early stages of cycling tank. It's been running for about a week.
I'm getting heavy bubble flow into the collection cup causing water to accumulate. Is this because their is a lack of skimmate during cycle? or is their a way to adjust the gate valve to reduce water from coming in? It is currently in the open position, the more I close it , the more bubbles and water accumulate in the collection cup. Any thoughts as to why this is happening?
