Water movement is one of the most important aspects of maintaining a healthy reef aquarium. Proper flow helps distribute nutrients, deliver oxygen to fish and corals, prevent detritus build-up, and support overall system stability. EcoTech Marine’s VorTech circulation pumps and Vectra return pumps are among the most advanced and popular flow solutions available, offering exceptional performance, wireless control, and integration through the Mobius ecosystem.
If you’ve recently purchased an EcoTech pump, this guide will walk you through the installation, setup, and initial configuration process to ensure you get the best possible performance from your equipment.
Why Choose EcoTech Pumps?
EcoTech Marine has built a strong reputation among reef aquarists thanks to innovative designs and advanced control capabilities.
VorTech Pumps
VorTech pumps are designed specifically for in-tank water circulation and feature:
- External motor design
- Broad, natural flow patterns
- Minimal heat transfer
- Wireless Mobius control
- Quiet operation
- Easy maintenance
Vectra Pumps
Vectra pumps are designed primarily as return pumps and offer:
- Variable speed control
- Feed modes
- Mobius integration
- High energy efficiency
- Quiet operation
- Flexible plumbing options
Whether you’re setting up a reef tank for the first time or upgrading existing equipment, correct installation is essential for long-term success.
Before You Begin
Before installing your pump, ensure you have:
- A suitable power outlet
- Access to the Mobius app
- Stable aquarium plumbing (for Vectra pumps)
- Clean aquarium glass (for VorTech pumps)
- Adequate cable routing
Take a few minutes to plan the placement of your equipment before installation.
Setting Up an EcoTech VorTech Pump
VorTech pumps use a unique magnetically coupled design that places the motor outside the aquarium while the wet side remains inside.
Step 1: Select the Correct Location
Positioning is critical for effective circulation.
General recommendations include:
- Upper third of the aquarium
- Opposite return nozzles
- Away from sand beds where possible
- Positioned to minimise dead spots
For larger tanks, multiple pumps may be required.
Step 2: Clean the Glass
Before mounting the pump:
- Wipe both sides of the glass
- Remove algae and debris
- Ensure surfaces are completely clean
This helps achieve proper alignment and secure mounting.
Step 3: Install the Wet Side
Place the wet side assembly inside the aquarium at your chosen location.
Ensure:
- The pump intake is unobstructed
- Nearby corals have adequate clearance
- Rockwork does not restrict flow
Step 4: Align the Dry Side
Position the dry side motor on the outside of the glass directly opposite the wet side.
The magnetic coupling will secure both components together.
Take time to achieve perfect alignment.
Proper alignment:
- Reduces noise
- Improves efficiency
- Minimises wear
Step 5: Connect Power
Attach the power supply and connect the pump.
The controller should illuminate, indicating the unit is ready for programming.
Connecting VorTech Pumps to Mobius
Mobius allows complete wireless control of your EcoTech equipment.
Download Mobius
Available on:
- iOS
- Android
Add Your Device
- Open Mobius
- Select “Add Device”
- Allow Bluetooth access
- Choose your VorTech pump
- Assign it to your aquarium
Once connected, you’ll have access to all available flow modes and schedules.
Recommended Initial VorTech Settings
Mixed Reef Aquariums
Start with:
- Reef Crest Mode
- 50–70% power
This provides varied, natural flow suitable for most coral types.
SPS-Dominated Systems
Start with:
- Reef Crest Mode
- 70–100% power
Monitor coral response before increasing intensity further.
LPS Aquariums
Start with:
- Lagoon Mode
- 40–60% power
This provides gentler, more consistent movement.
Understanding VorTech Flow Modes
Reef Crest Mode
Simulates turbulent reef environments.
Ideal for:
- SPS corals
- Mixed reefs
- Natural flow patterns
Lagoon Mode
Provides calmer, smoother circulation.
Ideal for:
- LPS corals
- Soft corals
- Lower-energy systems
Nutrient Transport Mode
Designed to:
- Lift detritus
- Improve filtration efficiency
- Reduce dead spots
Many hobbyists run this mode daily.
Pulse Modes
Create wave action and alternating currents that replicate natural reef movement.
Setting Up an EcoTech Vectra Return Pump
Unlike VorTech pumps, Vectra pumps are installed within your sump or return system.
Step 1: Position the Pump
Place the Vectra pump in the return chamber of your sump.
Ensure:
- Stable placement
- Adequate water depth
- Easy access for maintenance
The pump should never operate dry.
Step 2: Connect Plumbing
Attach the pump to your return line using appropriate fittings.
Common options include:
- Flexible hose
- PVC plumbing
- Union fittings
Always ensure connections are watertight.
Step 3: Install a Valve (Optional)
Many aquarists include a valve in the return line.
Benefits include:
- Easier maintenance
- Flow adjustments
- Improved servicing access
Step 4: Connect Power
Connect the power supply and controller.
The pump will begin its startup sequence.
Step 5: Prime the System
Fill plumbing and return lines with water before running the pump.
Check for:
- Air pockets
- Leaks
- Unusual noise
Proper priming helps maximise efficiency.
Connecting Vectra Pumps to Mobius
The process is similar to VorTech setup.
In Mobius
- Select Add Device
- Locate your Vectra pump
- Assign it to your aquarium profile
Once paired, you’ll gain access to:
- Flow adjustments
- Feed modes
- Return schedules
- Performance monitoring
Adjusting Vectra Flow
One of the biggest advantages of the Vectra range is variable speed control.
Recommended Starting Point
Aim for:
- 3–5x display volume per hour through the sump
For example:
A 500-litre aquarium may require approximately:
1,500–2,500 litres per hour
through the return system.
Excessive return flow rarely improves filtration and may increase noise and power consumption.
Using Feed Mode
Both VorTech and Vectra systems offer feed modes.
When activated:
VorTech Pumps
Reduce circulation temporarily.
Vectra Pumps
Reduce or pause return flow.
Benefits include:
- Improved feeding efficiency
- Less food entering filtration
- Better coral feeding response
Most feed modes automatically resume normal operation after a preset period.
Creating a Daily Flow Schedule
For advanced users, Mobius allows fully automated scheduling.
Example reef schedule:
Morning
Lagoon Mode
50%
Midday
Reef Crest Mode
80%
Afternoon
Nutrient Transport Mode
15 minutes
Evening
Reef Crest Mode
70%
Night
Lagoon Mode
40%
This creates dynamic flow patterns that more closely mimic natural reef environments.
Common Installation Mistakes
Avoid these common errors:
Poor VorTech Alignment
Can cause:
- Noise
- Vibration
- Reduced efficiency
Oversized Return Flow
May result in:
- Excess noise
- Reduced sump efficiency
- Microbubble issues
Ignoring Maintenance Access
Always position pumps where servicing remains easy.
Running Excessive Power Immediately
Increase flow gradually and monitor coral response.
Maintenance Tips
Regular maintenance ensures optimal performance.
VorTech Pumps
Every 4–8 weeks:
- Remove wet side
- Soak in aquarium-safe cleaner
- Remove calcium deposits
Vectra Pumps
Every 2–3 months:
- Disassemble pump
- Clean impeller
- Remove debris and buildup
Routine maintenance improves efficiency and extends equipment lifespan.
Troubleshooting Common Issues
Excessive Noise
Check:
- VorTech alignment
- Pump cleanliness
- Loose fittings
Reduced Flow
Inspect:
- Impeller
- Wet side components
- Obstructions
Connectivity Issues
Try:
- Updating Mobius
- Restarting Bluetooth
- Re-pairing devices
Most issues are easily resolved through regular maintenance and proper setup.
