Placement Options:
The skimmer offers flexible placement options:
- Hang-in-Rear or Side Sump: Recommended for optimal performance and minimal microbubbles in the display tank. Requires a minimum of 3.3 inches of space.
- Hang-in-Tank: Can be placed directly in the display tank, though some fine bubbles may enter the tank.
- Hang-in-Cabinet Sump: Suitable for larger sump setups.

Operating Instructions
Once installed, the skimmer requires minimal adjustment for optimal performance.
Adjusting Skim Level:
The rotatable body allows you to set the desired water level for either moist or dry foam production. Rotate the skimmer body to raise or lower the foam level in the collection cup. For a drier skim, lower the water level; for a wetter skim, raise it.

The air intake silencer helps reduce noise and allows for fine-tuning of the bubble level.

Maintenance
Regular maintenance ensures the longevity and efficiency of your protein skimmer.
- Empty Collection Cup: The skim mate collection cup stores organic and inorganic waste. It should be emptied and cleaned regularly (e.g., daily or every few days, depending on bioload) to prevent overflow and maintain skimmer efficiency. The cup can be easily removed for cleaning.
- Clean Skimmer Body and Pump: Periodically (e.g., monthly), disassemble the skimmer body and pump to clean any accumulated detritus or algae. Use a soft brush and warm water. Avoid harsh chemicals.
- Check Tubing: Ensure all tubing is free from kinks and blockages.
