EcoTech Marine VorTech MP10 Fish Guard & Anemone Guard Design and Creation

Engineering a Better Way to Protect Fish, Anemones, and Reef Tank Livestock

The EcoTech Marine VorTech MP10 is widely regarded as one of the finest wave makers available for nano and medium-sized reef aquariums. Its unique magnetically coupled design keeps the motor outside the aquarium, reduces heat transfer, minimizes equipment inside the display, and produces the wide, natural flow patterns that reef hobbyists love.

Whether you’re keeping SPS corals, LPS corals, soft corals, or a mixed reef aquarium, the MP10 has become a favorite because of its reliability, efficiency, and exceptional water movement.

Unfortunately, like every high-performance wave pump, the VorTech MP10 can also present a danger to the very livestock it’s designed to support.

Bubble Tip Anemones, Rock Flower Anemones, clownfish, gobies, blennies, shrimp, snails, and other reef inhabitants can accidentally come into contact with the wet side of the pump. In the worst cases, a wandering anemone can be pulled into the intake, resulting in livestock loss, poor water quality, and potentially a catastrophic chain reaction inside the aquarium.

That challenge inspired this project.

In this video, I document the complete design and creation process behind a custom EcoTech Marine VorTech MP10 Fish Guard and Anemone Guard, including measuring the pump, CAD modeling, 3D printing prototypes, testing, refining the design, and producing the final product.

The goal was simple:

Design a guard that helps protect valuable reef tank livestock while maintaining the outstanding flow performance that has made the MP10 one of the most trusted wave pumps in the reef aquarium hobby.

Why Does the EcoTech Marine MP10 Need a Fish Guard?

Strong water movement is essential for a healthy reef aquarium.

Proper circulation helps:

Deliver nutrients to corals
Remove waste
Improve oxygen exchange
Prevent detritus buildup
Promote coral growth
Create natural reef-like water movement

The MP10 excels at all of these tasks.

However, its powerful intake can occasionally create problems for aquarium inhabitants.

Common risks include:

Wandering Bubble Tip Anemones

Bubble Tip Anemones are among the most popular reef aquarium animals.

Unfortunately, they also have a tendency to relocate when conditions change.

Even healthy anemones may move because of:

Changing water flow
Lighting adjustments
Nearby coral growth
Water chemistry
Competition for space

If an anemone encounters an unprotected MP10 wet side, it can be severely damaged.

Small Fish

Juvenile clownfish, gobies, firefish, blennies, dartfish, and other small species may occasionally be pulled against the intake.

Snails and Cleanup Crew Members

Turbo snails, trochus snails, cerith snails, and other cleanup crew members frequently climb powerheads and can interfere with operation.

Shrimp and Other Invertebrates

Cleaner shrimp, peppermint shrimp, sexy shrimp, porcelain crabs, and other mobile invertebrates often explore every inch of the aquarium—including wave pumps.

A purpose-built fish guard helps reduce these risks while allowing the MP10 to continue producing the circulation your reef depends on.

Why I Designed an MP10 Fish Guard

I’ve spent years designing custom accessories for reef aquariums and one request continued to appear over and over again:

“Can you make a guard for the EcoTech MP10?”

Given the popularity of the VorTech series, it was only a matter of time.

Rather than adapting an existing design, I wanted to engineer a guard specifically around the unique geometry of the MP10 wet side.

The objective wasn’t simply to place a screen over the intake.

The objective was to create a product that:

Looks like it belongs on the pump
Preserves flow
Installs easily
Protects livestock
Is easy to maintain
Can withstand years of reef aquarium use

Understanding the Design Challenges

Creating a fish guard involves much more than simply covering openings.

Every design decision affects performance.

Livestock Protection

Openings must be small enough to reduce risk to fish and anemones.

Water Flow

The MP10 is known for producing a broad, efficient flow pattern.

The guard must preserve that performance.

Structural Strength

Thin components improve flow but reduce durability.

Thicker components improve strength but can increase restriction.

Ease of Cleaning

A practical design must remain easy to remove and clean as algae and coralline accumulate.

Appearance

The VorTech MP10 is beautifully engineered.

The guard needed to complement the pump rather than distract from it.

Measuring the VorTech MP10

Every successful project begins with accurate measurements.

The first step involved carefully measuring every critical feature of the MP10 wet side.

Measurements included:

Intake openings
Curved housing surfaces
Outside diameter
Mounting geometry
Internal clearances
Flow pathways

These dimensions were recreated inside CAD software to produce a precise digital model.

This virtual reference allowed numerous concepts to be evaluated before manufacturing physical prototypes.

CAD Modeling and Product Development

With the digital reference complete, the engineering process began.

Multiple guard concepts were created and evaluated.

Each version attempted to optimize several competing priorities:

Livestock safety
Water movement
Strength
Ease of installation
Ease of manufacturing
Visual appearance

Every revision brought the design closer to the final product.

Bringing the Design to Life with 3D Printing

3D printing has transformed the way reef aquarium accessories are developed.

Instead of waiting weeks for tooling, new prototypes can be printed, tested, modified, and improved in a matter of hours.

Numerous prototype versions were produced during development.

Each was evaluated for:

Fitment
Structural integrity
Installation
Water flow
Overall appearance
Livestock protection

This iterative process is one of the biggest advantages of modern product development.

Real-World Testing

Testing inside an actual reef aquarium is where engineering meets reality.

Every prototype was evaluated under operating conditions to verify:

Flow Performance

Maintaining the wide flow characteristics that make the MP10 so effective.

Fish Protection

Reducing opportunities for fish to contact the intake.

Anemone Protection

Providing an additional layer of protection for wandering anemones.

Ease of Cleaning

Making routine maintenance quick and simple.

Long-Term Durability

Ensuring reliable performance inside a saltwater environment.

Only after passing each of these stages was the design considered ready for production.

Benefits of the Finished MP10 Fish Guard

The final design offers numerous advantages.

Fish Protection

Helps reduce the likelihood of fish contacting the intake.

Bubble Tip Anemone Protection

Provides additional protection for one of the hobby’s most popular anemones.

Snail Protection

Helps prevent snails from interfering with pump operation.

Shrimp Protection

Adds protection for mobile invertebrates.

Strong Water Movement

Maintains the excellent circulation characteristics of the MP10.

Quick Installation

Designed for fast installation without modifying the pump.

Factory-Inspired Appearance

Blends naturally with the sleek design of the VorTech MP10.

Frequently Asked Questions

Does the MP10 Fish Guard reduce flow?

Every intake guard creates some restriction, but this design was engineered to preserve as much water movement as possible while significantly improving livestock protection.

Will it protect my Bubble Tip Anemone?

No guard can eliminate every possibility of an accident, but it can greatly reduce the likelihood of a wandering anemone reaching the pump intake.

Is the guard reef safe?

Yes. The production version is manufactured from materials intended for long-term reef aquarium use.

Does installation require modifying the MP10?

No. The guard installs without permanently altering the pump.

Why not use a foam intake cover?

Foam covers often clog quickly, reduce flow, require frequent cleaning, and can detract from the appearance of the aquarium. This design was developed to provide a cleaner, more durable solution.
