Maxspect Jump Protein Skimmer SK2400 G2
Serious Nutrient Export for Larger, Heavily Stocked Reef Aquariums
When your reef grows, so does the amount of organic waste your filtration system needs to handle. The Maxspect Jump SK2400 G2 is built for reefers who need more skimming power without sacrificing quiet operation, control, or ease of maintenance.
With Maxspect's Gen 2 dual needle-wheel technology, dual water intake design, optimized reaction chamber, DC flow control, and intelligent overflow protection, the SK2400 G2 delivers efficient protein skimming for medium-to-large reef systems and heavily stocked aquariums.
And because it uses sine-wave technology, the SK2400 G2 is engineered to operate quietly—an important advantage when your aquarium is part of your living space.
Why Choose the Maxspect Jump SK2400 G2?
High-Performance Dual Needle-Wheel Skimming
At the heart of the SK2400 G2 is Maxspect's patented dual needle-wheel design, engineered to efficiently mix water and air and create a dense population of fine microbubbles.
The Gen 2 reaction chamber is optimized to improve the air-to-water ratio, helping the skimmer efficiently capture dissolved organic compounds before they have a chance to break down and contribute to unwanted nutrients.
Powerful Without the Noise
More skimming power doesn't have to mean more noise.
The SK2400 G2 uses sine-wave technology to provide smoother pump operation compared with traditional pump technology. The result is refined, near-silent performance designed for reef systems where noise matters.
Whether your aquarium is in your living room, office, or bedroom, the SK2400 G2 is designed to work in the background—not become part of the soundtrack.
Precise DC Flow Control
Every reef aquarium is different.
The SK2400 G2 gives you control over pump speed and internal water level so you can tune the skimmer to your aquarium's particular bioload and sump conditions.
The precision front dial and adjustable water inlet make it easier to fine-tune foam production and achieve the skimming performance you're looking for.
Intelligent Overflow Protection
Skimmer overflows are one of the most frustrating problems in reef keeping.
The SK2400 G2's intelligent overflow protection is designed to help prevent organic waste from being pushed back into your aquarium.
When an overflow condition is detected, the controller automatically reduces the pump to its lowest speed rather than shutting it completely off. This helps maintain oxygenation while minimizing sudden changes to your system.
Once the collection cup has been emptied and the sensor confirms normal operation, the controller automatically returns the pump to its previous operating speed.
Feed Mode & Startup Delay
The smart controller includes convenient functions such as Feed Mode and Start Delay, making everyday reef maintenance easier.
Pause or adjust skimming when feeding and allow the system to restart intelligently after maintenance or power interruptions.
Dual Water Intakes
The SK2400 G2 features dual water intake pathways designed to improve water movement through the skimmer.
Maxspect also allows the right-side water inlet to be fully adjusted, giving you additional control over the skimmer's internal water level and performance.
Optimized Gen 2 Reaction Chamber
The redesigned spiral reaction chamber provides a smoother bubble ascent and efficient water movement through the skimmer.
Combined with the optimized air-to-water ratio, the Gen 2 design is engineered to produce finer, denser microbubbles for efficient protein skimming.
Quick-Release Maintenance
A protein skimmer can only perform at its best when it is kept clean.
The SK2400 G2 features a quick-release design that makes routine disassembly and cleaning easier. The silencer is also detachable and fully cleanable, helping simplify long-term maintenance.
Less time cleaning equipment means more time enjoying your reef.
What Size Aquarium Is the SK2400 G2 Best For?
Maxspect rates the SK2400 G2 according to aquarium bioload rather than using a single maximum tank-size number.
| Aquarium Bioload | Recommended Aquarium Size |
|---|---|
| High Bioload | Up to 105 gallons |
| Medium Bioload | Up to 185 gallons |
| Low Bioload | Up to 264 gallons |
These ratings are important when choosing a skimmer.
A 180-gallon aquarium with a large fish population and heavy feeding demand can require significantly more skimming capacity than a lightly stocked 180-gallon reef.
WWC Tip
Choose your skimmer based on your actual bioload—not just your aquarium's gallon capacity.
If you run a heavily stocked reef, feed heavily, or keep a substantial fish population, use the high-bioload rating when deciding which skimmer is right for you.
