Protein Skimmer is designed for in-sump use only.Skimmer will require 24 - 48 hours to "break-in" in some cases longer depending on the bio-load, during which time an excess of waste and bubbles might appear. Let skimmer run for a few hours before adjusting the water level. Once the skimmer has settled you can adjust the water level inside the skimmer to obtain a better consistency in foam production. The side opening on the second chamber is normal and will prevent the water from getting to the collection cup. Keep skimmer in a calm area of the sump away from turbulence. Dry skimming can be achieved by adjusting the water level in skimmer. Use the water level adjuster (see 1st page of instructions in box) to lower the water level.Note: Water on second chamber is normal and will not affect the performance of the skimmer. The opening on top of second chamber prevents the collection cup from overflowing.
