Aquarium Protein Skimmer – Saltwater Marine Tank Filter
Aquarium Protein Skimmer – Saltwater Marine Tank Filter
Keep Your Marine Aquarium Crystal Clear
Give your saltwater fish the clean, oxygen-rich environment they deserve. This Aquarium Protein Skimmer uses air-bubble technology to continuously pull protein colloids, organic particles, and unwanted heavy metal compounds out of your marine tank water — before they can affect water quality. Made in Mainland China from high-quality, durable plastic, it is built to hang on the side of your tank for easy, out-of-the-way installation.
How It Works
Connect the skimmer to your existing air pump (sold separately). The pump drives a stream of fine air bubbles through the unit. These bubbles attract and adsorb protein colloids, dissolved organics, and other impurities via changes in water surface tension. The contaminated foam rises into the built-in collection cup, separating waste from your water before it ever decomposes — keeping ammonia and nitrate levels low and your aquarium water noticeably cleaner and clearer.
Key Features
- Premium Durable Plastic — Solid, corrosion-resistant construction designed for long-term saltwater use.
- Effective Foam Fractionation — Removes protein colloids, organic particles, and heavy metal compounds efficiently.
- Increases Oxygen Exchange — The air inlet tube introduces extra oxygen into the water column, supporting healthier fish and coral.
- Hang-On Design — Mounts easily on most standard aquarium walls; no complex installation required.
-
Two Size Options — Available in Small and Large to suit a wide range of marine tank volumes:
- Small (S): 23.5 × 9.5 × 8.5 cm
- Large (L): 29 × 12.5 × 11 cm
- Easy to Set Up — Simply attach your air pump tubing and it's ready to run; no tools needed.

Frequently Asked Questions
Q: What size aquarium is this protein skimmer suitable for?
A: The skimmer is available in two sizes — Small (23.5 × 9.5 × 8.5 cm) and Large (29 × 12.5 × 11 cm) — designed to fit most standard saltwater and marine fish tanks. Choose the size that best matches your tank volume for optimal performance.
Q: Does the protein skimmer come with an air pump?
A: No, an air pump is not included. You will need to connect the skimmer to a separately purchased air pump using standard aquarium air tubing. Most common aquarium air pumps are compatible.
Q: Can I use this skimmer in a freshwater aquarium?
A: This protein skimmer is specifically designed and optimized for saltwater and marine aquariums. Protein skimming works most effectively in saltwater due to the higher surface tension of salt water, which supports stable foam formation and efficient waste collection.
Q: How often do I need to clean the collection cup?
A: The frequency depends on your tank's bio-load. In heavily stocked marine tanks, you may need to empty and rinse the collection cup every few days. For lightly stocked tanks, weekly cleaning is typically sufficient. Regular maintenance ensures the skimmer continues to operate at peak efficiency.
Q: Is the skimmer easy to install?
A: Yes! The hang-on design allows you to clip the unit to the side of your aquarium wall without any tools. Simply connect your air pump tubing to the air inlet and it's ready to use — making setup quick and straightforward for both beginners and experienced aquarists.
