Zoomable history graphs with your safe range shaded behind the data, trend detection, and forecasts that warn you before a drifting value leaves its range.
A supplement plan built on a catalog of reef brands, full dosing history, and calculators PRO that turn your readings into a recommended daily dose or a safe correction plan.
Water changes, media changes and cleanings in one log, an elastic maintenance schedule that never stacks phantom overdue warnings, RO/DI filter life tracking, and opt-in notifications.
