Imagine a world where manual nitrate and phosphate tests are no longer apart of your aquarium maintenance routine. Now you don't have to imagine! The Trident NP is the latest innovation from Neptune Systems, designed to automate Nitrate and Phosphate testing with precision and ease. Building on the trusted reputation of the original Trident, the Trident NP offers high-frequency testing to ensure optimal water quality in your aquarium. With seamless integration into the A2 and A3 Series Apex Controllers, the Trident NP brings consistent, automated measurement of nitrate and phosphate levels inside your aquarium so that you can make better decisions or even automate actions to maintain stability in your system.


With Every Trident:

Easy Plug and Play Setup - From the box to testing in under 10 minutes! Unlike other testing systems, there are no reagents to mix, tubes to cut, or pumps or probes to calibrate.

Easy to Read Results and Graphs - The peace of mind of having your recent tank parameters, right there in your pocket, from anywhere in the world.

High/Low Alerts When Tank is Out of Range - Your Apex will alert you on your mobile device when test results fall out of the range you specify.

Automated Dosing Control - Combine Trident with DOS Quiet Drive (sold separately), and your Apex will utilize Trident’s data to automatically and safely modify your dosing.


Take Your Aquarium Success to the Next Level

When you start receiving regular data from the Trident you will be amazed at the things you can see happening. This increased understanding ultimately helps you maintain a better, more successful reef.


Automate Your Dosing with Trident and DŌS

The more stable your aquarium levels, the better your corals will grow and thrive. Your tank however is continually evolving and the need for different additives and buffers can change rapidly, and may leave your dosing out of sync.

The Trident, when paired up with one or more DŌS systems, solves this problem with Automatic Dosing Control (ADC). ADC will take results from the Trident and use them to gradually adjust what the DŌS delivers. Safeguards protect your aquarium from errors in the readings by measuring change against dosing, and dosing will only adjust +/-35% per adjustment, Failure to log change will shut down the auto tune, notify you and revert to original dosing levels

Does this replace my existing Trident or go side by side with it?
