Automated Testing
Neptune Systems Trident Quick Buyer’s Guide
Not every reef tank needs the same kind of automated testing. Understanding what each Trident measures can help you decide which tester makes the most sense for your tank and whether adding both would give you a more complete view of your reef.
What the Trident ACM Measures
- Focus: Core reef chemistry
- Tests: Alkalinity, calcium, and magnesium
- Why it matters: Critical for coral growth and skeletal development
- Use case: Dialing in dosing and stability
What the Trident NP Measures
- Focus: Nutrient levels and balance
- Tests: Nitrate and phosphate
- Why it matters: Impacts algae, coral color, and overall system health
- Use case: Managing feeding and filtration
Can I Use Both Together, and Why Would I?
Yes. Using both gives you a more complete understanding of your reef. The ACM tracks the elements corals consume, while the NP tracks nutrients that influence algae and feeding response.
Together, they help connect cause and effect so you can make smarter decisions.
- Big picture: Chemistry + nutrients
- Benefit: Better insight into tank changes
- Best for: Established and SPS systems
Does the Trident Require Maintenance or Extra Equipment?
Yes. Both testers require reagents and periodic upkeep to maintain accuracy.
They are not standalone devices and must be used with an Apex controller to view data and manage alerts.
- Apex required: Required for operation
- Reagents: Needed for testing
- Testing: ACM runs multiple times daily, NP runs daily
- Expandability: Works with dosing and Apex ecosystem
Control Everything with Apex Fusion
All Neptune automated testing is powered through Apex Fusion, Neptune Systems’ cloud-based interface that lets you monitor and control your aquarium from anywhere. Whether you are at home or away, Apex Fusion gives you real-time access to your tank’s data through your phone, tablet, or computer.
Instead of manually checking parameters and guessing at trends, you can view detailed graphs, receive alerts, and respond quickly when something changes. This makes it easier to stay ahead of problems and keep your reef stable over time.
- Access anywhere: Check your tank from any smart device with an internet connection
- Real-time monitoring: View live test results and historical trends
- Smart alerts: Get notified when parameters move outside your set range
- Data-driven decisions: Use trends to fine-tune dosing, feeding, and filtration
- Simple interface: Easy to navigate whether you are new or experienced
Frequently Asked Questions
What does the Neptune Trident ACM test?
The Trident ACM tests alkalinity, calcium, and magnesium.
What does the Neptune Trident NP test?
The Trident NP tests nitrate and phosphate.
Do I need an Apex controller?
Yes, both testers require a compatible Neptune Systems Apex controller to operate and view results.
Are reagents required?
Yes, reagent kits are required for both testers to perform automated tests.
How often do tests run?
The ACM can run multiple tests daily, while the NP runs one automated test per day with optional manual tests.
Is automated testing worth it?
For many reef keepers, automated testing saves time and helps identify trends before they become problems.
Should I start with ACM or NP?
Start with ACM for coral stability, or NP for nutrient control. Many reefers eventually use both.
Can this help with dosing?
Yes, automated testing provides consistent data that helps fine-tune dosing and maintain stability.
