An aquarium controller built for everyday reef tanks
The Nereus aquarium controller is a reef aquarium controller focused on the parameters reefers watch every day: pH, temperature, and a third digital sensor input. It works on the Nereus platform — the same live dashboard as the Dual-Head Doser — and sends push notifications the moment values leave your safe range.
Whether you run SPS, a mixed reef, or a fish-heavy system, continuous logging gives you a clear story of tank stability instead of snapshots from a handheld meter.
What this aquarium controller monitors
- Live pH and temperature for reef aquarium systems
- A third digital sensor channel for expansion
- Real-time charts on the Nereus dashboard
- Out-of-range push alerts for pH and temperature
- Manual test logging for Alk, NO₃, PO₄, Mg, Ca and more
Why reefers use an aquarium controller
An aquarium controller does not replace husbandry — it makes problems visible sooner. Drifting pH, a stuck heater, or a slow temperature climb show up on charts and on your phone before corals pay the price. Pair it with dosing and nutrient control so every reading sits next to the actions you take.
Built for the full Nereus workflow
Use this aquarium controller alongside the Dual-Head Doser, ATO, and Alkalinity Checker. One brand, one platform, one clear picture of reef health — from monitoring to automated dosing and alkalinity checks.
