Exceptional Waste Removal

Pulls in more air than expensive competitors producing a dense waste-removing foam. The hybrid cone body helps concentrate the foam as it rises and improves contact time.

Custom Control

Perfectly dial in the skimmer with three points of control. Independently adjust the water level, the air intake, and the flow rate of the pump and achieve the best performance for your unique system.

Controllable Pump

Increase or decrease the water flow rate with the touch of a button. This feature is helpful when adding medications or foods to the tank that can cause the skimmer to overflow. The built-in feed mode allows the pump to be turned off temporarily with the touch of a button.

Compact, Hybrid Cone Design

The hybrid cone design stabilizes the foam column and concentrates it as it rises, maximizing waste removal.

Needle Wheel Impeller

A durable needle wheel impeller is the powerhouse of the pump creating tons of microbubbles that capture detritus and push it into the collection cup.

Easy-to-perform Maintenance

The thumbscrew assembly makes taking the skimmer apart simple, and the bayonet locking collection cup is simple to remove and clean. Includes a built-in collection cup drain for those away from their tank for an extended time.

Low Power Consumption

The DC pump is energy efficient and safer than a similar sized AC pump.

Unbeatable Value

Other skimmers with similar features sell for more than double the price.

How We Photograph Our Corals

Every WYSIWYG photo on The Twin Corals Shop is captured directly in our systems using meticulous settings to ensure absolute transparency. Our goal is straightforward: show the coral precisely as it appears in a well-maintained reef aquarium — never heavily filtered or artificially saturated.

Our Camera & Optics

• Camera: Panasonic Lumix G85
• Lens / Mode: Olympus M.Zuiko Digital ED 60mm f/2.8 Macro Lens
• ISO: 50
• White Balance: Custom set between 9,000K–10,000K

This setup allows us to highlight the finest structural details — from delicate polyp extension and skeletal texture to subtle gradient color shifts — without washing out the true look of the animal.

Lighting We Shoot Under

• Fixtures: Nicrew Hyperreef Gen2 (100W or 150W depending on the system)
• Photo Spectrum Mix: White 5% · Violet 60% · UV 60% · Deep Blue 50%

Color Accuracy & Your Tank

By utilizing a targeted custom white balance, our photos closely mirror what you will see under a clean, balanced blue-leaning reef spectrum.

Keep in mind that corals are living organisms; their appearance can naturally shift from tank to tank depending on your specific water parameters, nutrient levels, lighting spectrum, and flow patterns. We strive to provide honest, dependable photos you can trust so your new coral looks right at home from day one.
