A modern reef aquarium with its equipment and sump

Live app

Build your aquarium digital twin

Model your aquarium, sump, equipment, plumbing, power, data topology, and effective volume so every other app understands your system.

What you can do

Systems

  • Build your own digital aquarium twin on the platform.
  • Add your products and place them in your aquarium, sump, cabinet, room, or even outside.
  • Create your own user-defined products.
  • Link products together to show how they interact with each other.
  • Model plumbing, control, and power connections.
  • Add displacement products like substrate and rocks.
  • Calculate the real water volume — vital for dosing calculations.
  • Define your system type with options such as SPS, LPS, Mixed Reef, and FOWLR.
  • Choose your salt product to set your base parameters.
  • Set replacement schedules and alerts for consumables such as RO filters, UV tubes, and filter media.
  • Share your setup with other users via a forum banner.

Typical workflows

  • Map display tanks, sumps, refugiums, compartments, and effective water volume.
  • Record pumps, lights, heaters, controllers, consumables, and custom equipment.
  • Connect plumbing, power, and data relationships so the model reflects the real setup.

What you get

  • A single source of truth for every other MyCeto app.
  • Cleaner context for troubleshooting, advice, and future device integrations.
