System versions

One system that grows with you

The same hardware, three profiles matched to your tank type. We take freshwater, planted and marine aquariums equally seriously — they differ in functionality, not in rank. Switch profiles — without replacing any hardware.

Oquari Fresh

Freshwater aquarium

A complete freshwater tank controller — from temperature to energy costs.

  • temperature with multi-layer heater protection and cooling
  • a light plan with sunrise and sunset ramps
  • ATO top-off with the full package of safeguards
  • automatic water changes straight from the RO filter
  • two dosing channels with calibration
  • schedules for the metered outlets + energy metering on every circuit
  • feeding, service/vacation modes, leak alarms and phone notifications
Oquari Plant

Planted aquarium

High-tech precision: water chemistry under probe control, fertilization to the milliliter.

  • every feature of the freshwater profile
  • CO₂ driven by actual pH, in rhythm with the light
  • a pH probe with a calibration wizard and electrode health assessment
  • four dosing channels for macro and micro fertilizers
  • a siesta (midday dimming break) in the light plan
Oquari Marine

Reef and marine

Full reef automation — with constant-salinity water changes and waves like in nature.

  • every feature of the planted profile
  • redox (ORP) and salinity measurement (PSU + specific gravity)
  • water changes with a saltwater mixing reservoir and probe-verified salinity
  • wave pump programs with tidal mode and night mode
  • dosing with spacing between liquids (marine chemistry)
  • full predictive equipment diagnostics

Starting with freshwater and setting up a reef next year? Your Oquari moves with you — expand the system with the probe module and switch the profile to Marine. No controller replacement.
