The Trident analyzer works seamlessly with my Apex controller. I no longer have to manually test water parameters. Results appear instantly on my phone and the dosing system adjusts automatically. My tank has been more stable since I started using it.

Easy to set up and reliable. I tested alkalinity, calcium, and magnesium regularly. The readings are consistent and the app interface is clean. Only downside is the initial setup took a few hours to configure with the dosing system.
