The new portal to better monitor your marine aquarium.
From the DIY doser and Joyreef guides comes a more complete space: tank data, history, notifications, automations and DIY devices, all in one place. The same approach as the blog, now in a dedicated portal.
Free, no credit card required. Designed for those who truly keep a reef.
Joy Reef wasn't born from a boardroom. It comes from a marine aquarium enthusiast who, for their own tank, started writing guides, testing solutions and building DIY electronics — from dosers to sensors.
That work became a reference point for other reef keepers. The portal is the next step: gathering data, automations and devices into a single tool, built with the same concrete spirit and no shortcuts.
Same passion, same technical attention — just more organised and accessible.
Articles on corals, water chemistry and tank technique, written from real experience.
Schematics, firmware and Arduino projects: accessible hardware, shared code, everything explained step by step.
Data, history, notifications and automations in one place, with compatible DIY devices connected.
The portal helps you keep a close eye on your tank. It doesn't replace the reef keeper's eye: it gives better tools.
Keep all your marine aquarium information together: setup, activities and reminders, always at hand.
Record parameters over time and read your tank's trend with charts and history, instead of relying on memory.
Set thresholds and get an alert when something goes outside your expected values, before it becomes a problem.
Schedule recurring actions — like dosing — and let the daily routine follow the rules you set.
Connect the DIY electronics from Joy Reef guides — like the doser — and read data and status from the portal.
Connect with fellow enthusiasts, share experiences and join Reef Champions by earning points.
Nothing disappears. The old ecosystem remains available as an archive, but the starting point for new users is the portal.
The guides, schematics and firmware published over the years remain available for reference.
If you're starting today, start here: the portal brings together the blog experience in an updated and maintained tool.
The portal is in beta: open to everyone, free and no card required. We are building it together with enthusiasts, and real feedback from tank keepers matters more than any roadmap.
Create your portal access and start monitoring your tank. It only takes a few minutes, and you can join and leave whenever you want.
