Dive Deeper: Info & Tips for Maxspect Gyres
Maxspect revolutionized reef tank water movement with the introduction of gyre-style pumps — delivering wide, powerful, and evenly distributed flow across the entire aquarium. Unlike traditional propeller pumps, Maxspect Gyres create a consistent horizontal current that eliminates dead zones and promotes better coral health and nutrient export.
At Top Shelf Aquatics, we stock the full lineup of Maxspect Gyre Pumps, including the high-performance XF350 and the compact XF330 series. These pumps are known for their efficient crossflow technology, silent operation, and broad coverage, making them ideal for a variety of reef setups.
While Maxspect also offers the Jump Series for hobbyists seeking more entry-level options, our focus remains on the professional-grade XF series — trusted by serious reef keepers for reliable, customizable flow control.
With advanced controllers, smart mounting options, and proven durability, Maxspect Gyres continue to be a top choice for optimizing circulation in both SPS-dominant reefs and mixed coral systems.
Choosing the Right Maxspect Gyre Pump for Your Aquarium:
Maxspect XF350:
Designed for larger reef tanks, the XF350 delivers massive flow rates with minimal visual footprint. It's ideal for tanks over 100 gallons and features Maxspect’s Crossflow Technology to create wide, gentle currents across long distances. The XF350 includes advanced controller compatibility, allowing full customization of flow patterns, intensity, and scheduling.
Maxspect XF330:
Perfect for medium-sized aquariums, the XF330 offers the same powerful gyre flow design in a more compact package. It’s a great choice for tanks around 50–100 gallons, providing efficient water movement that reduces dead spots without overwhelming smaller systems. Like the XF350, it features programmable control options for tailored circulation.
Maxspect Gyre Controllers:
Both the XF350 and XF330 pair with intuitive Maxspect controllers, offering multiple preset modes such as constant speed, pulse, random, and gradual ramping. Controllers allow you to sync multiple pumps together, create custom daily schedules, and fine-tune your system’s water movement for maximum coral health and nutrient export.
Optimizing Maxspect Gyre Pump Performance
Place Pumps Horizontally for Maximum Crossflow:
Maxspect Gyres are designed to create wide, horizontal sheets of water movement. Install them horizontally along the top sides or back of the tank to sweep flow across the entire length of the aquarium, minimizing dead zones behind rockwork and coral structures.
Utilize Alternating Gyre Patterns:
Take advantage of alternating flow modes to simulate tidal currents. Switching the flow direction at intervals helps prevent detritus buildup and encourages natural coral behavior, such as polyp extension and feeding response.
Adjust Intensity to Coral Types:
High-flow-loving SPS corals thrive under stronger, turbulent gyre flow, while LPS and soft corals often prefer moderate, indirect movement. Program your XF350 or XF330 to ramp up or down throughout the day depending on the needs of your livestock.
Use Gyres in Pairs for Full Coverage:
Running two gyre pumps — one on each side of the tank — allows you to alternate flow directions more effectively, creating a true "back and forth" current across the entire display. This technique is especially useful for long reef tanks or aquascapes with multiple islands.
Schedule Lower Nighttime Flow:
Reduce flow speeds at night to mimic natural reef conditions when water movement typically slows. This gives fish and corals a resting period and can also help reduce stress, especially in more delicate species.
Expert Tips
Clean Gyre Rotors and Bushings Regularly
Gyre pumps rely on precise rotor balance. Calcium buildup, algae, and debris can cause imbalance and reduced performance. Soak the rotors, cages, and bushings in a vinegar solution every 4–6 weeks and gently scrub with a soft brush.
Fine-Tune Flow with Angle Adjustments
Even a slight tilt upward or downward can drastically change how water circulates around your rockwork. After installing your XF350 or XF330, make small angle adjustments to eliminate dead spots or areas of excessive turbulence.
Use Preset Pulse Modes to Target Specific Coral Needs
The Maxspect controllers include preset modes like random, pulse, and constant flow. Short pulses can be ideal for SPS corals, while random flow is often better for mixed reefs with a variety of coral types.
Keep Spare Rotors and Bushings on Hand
Over time, moving parts like rotors and bushings can wear out, especially in high-calcium reef environments. Having spares ready minimizes downtime if a part needs replacement during routine maintenance.
Ramp Flow Intensity Gradually Throughout the Day
Mimic natural tidal changes by starting with gentle morning flow, increasing intensity through the afternoon, and then scaling back in the evening. Gradual flow shifts can reduce coral stress and enhance feeding response.
Installation & Maintenance
Installing Your Maxspect Gyre Pump
Mounting the Pump:
Install the XF350 or XF330 horizontally along the upper sidewalls or back wall of your tank using the included magnetic mounting system. Ensure the pump is fully submerged and positioned to create broad cross-tank flow. Avoid placing the pump directly behind dense rock structures, as this can restrict the gyre’s effectiveness.
Connecting the Controller:
Connect your pump to the Maxspect controller and follow the quick-start guide to pair devices. Set your initial flow pattern using constant, pulse, or random modes, and adjust intensity based on the size of your tank and the flow preferences of your coral species.
Position for Full Tank Coverage:
In longer tanks, consider running a second gyre on the opposite wall. This allows alternating flow schedules, sweeping detritus into suspension and creating natural turbulence that benefits corals and overall tank health.
Routine Maintenance Tips
- Clean Rotors, Cages, and Bushings Monthly: Soak removable parts in a vinegar solution to dissolve calcium buildup. Gently scrub all surfaces to restore optimal flow output and motor balance.
- Inspect Magnet Mounts and Cable Sleeves: Wipe down magnets and check cable sleeves for salt creep or damage. Salt buildup near power connections should be cleaned immediately to prevent corrosion.
- Lubricate Bushings if Needed: Some bushings may benefit from a small application of aquarium-safe lubricant to maintain smooth rotor operation, especially after extended use.
- Check for Firmware Updates: For models paired with advanced Maxspect controllers or app integration, check periodically for firmware updates that may improve performance or add new scheduling options.
Monitor for Wear: If you notice unusual noise, reduced flow, or wobbling, inspect the rotor assembly for wear and replace any damaged parts to prevent further strain on the motor.
