Red StarFish SQ-90 Ultra Quiet Protein Skimmer – Marine Aquarium
Red StarFish SQ-90 Ultra Quiet Protein Skimmer – Marine Aquarium
Red StarFish SQ-90 Ultra Quiet Protein Skimmer – Saltwater Marine Aquariums (90–130L)
Keep your saltwater reef or marine aquarium crystal clear with the Red StarFish SQ-90 Protein Skimmer. Engineered for hobbyists who demand efficient, whisper-quiet filtration, this compact protein separator uses a proven needle-wheel impeller to maximise air-to-water contact, efficiently removing organic waste, proteins, and nitrogen compounds before they can break down and degrade your water quality.
Key Features
- Ultra-Quiet Operation – Designed for minimal noise, so your aquarium stays a peaceful centrepiece in any room.
- Needle-Wheel Impeller Technology – Maximises micro-bubble production and air-to-water contact for highly effective protein removal.
- Flexible Placement – Can be placed directly inside the aquarium or within a filtration/sump compartment using the included adjustable bracket.
- Quick-Lock Housing – Tool-free, quick-lock design makes routine cleaning and maintenance fast and hassle-free.
- Adjustable Mounting Bracket – Fits standard aquarium frames for secure, optional in-tank mounting.

Why Your Marine Tank Needs a Protein Skimmer
In saltwater and reef aquariums, dissolved organic compounds accumulate rapidly from fish waste, uneaten food, and decomposing matter. A protein skimmer removes these compounds at the molecular level — before they convert to harmful nitrogen byproducts — helping maintain stable water parameters, improved oxygen levels, and a healthier environment for corals, fish, and invertebrates. For more on maintaining healthy aquatic ecosystems, see the EPA Water Quality resources.
Who Is This Skimmer For?
The SQ-90 is the perfect upgrade for intermediate to experienced reef and marine aquarium hobbyists running tanks between 90 and 130 litres. Whether you are managing a FOWLR (fish only with live rock) setup or a thriving nano reef, the SQ-90 delivers reliable, efficient skimming in a compact, quiet package.
Frequently Asked Questions
Q: Can the Red StarFish SQ-90 protein skimmer be used in a freshwater aquarium?
A: No. Protein skimmers, including the SQ-90, are designed specifically for saltwater and marine aquariums. The salinity of saltwater is essential for creating the micro-bubbles that allow the skimmer to function correctly. Using it in freshwater will not produce effective results.
Q: Where can the SQ-90 protein skimmer be installed?
A: The SQ-90 offers flexible placement options. It can be placed directly inside the display aquarium using the included adjustable bracket, or it can be installed within a sump or filtration compartment. The working water level requirement is 200–220 mm.
Q: How often does the protein skimmer cup need to be cleaned?
A: This depends on your tank's bioload (number of fish, feeding frequency, etc.), but as a general guideline, the collection cup should be emptied and rinsed every 3 to 7 days. The quick-lock housing design makes this process quick and tool-free.
Q: What tank size is the SQ-90 rated for?
A: The SQ-90 is rated for saltwater aquariums between 90 and 130 litres (approximately 24–34 US gallons). Using it on a larger tank may result in reduced skimming efficiency.
Q: Is the SQ-90 compatible with 110V power outlets?
A: The SQ-90 operates at 220V. If you are in a region with 110V outlets (such as the USA or Canada), you will require a voltage converter/transformer before use. Please verify your local voltage requirements before purchasing.
