Log and track critical marine metrics directly on your primary dashboard:<br><br>Alkalinity &amp; pH: Monitor pH and Carbonate Hardness (kH in dKH).<br><br>Macro-Elements: Track Calcium (Ca in ppm) and Magnesium (Mg in ppm).<br><br>Nutrients: Observe Nitrate (NO3 in ppm) and Phosphate (PO4 in ppm).<br><br>Visual Trend Timelines: Utilize the View Trends module to generate visual graphs of your logged parameters over time. Spot minor chemical shifts early before they impact sensitive livestock or coral tissue health.<br><br>Husbandry &amp; Maintenance Planner: Keep your reef chores perfectly organized. Use the dedicated Maintenance portal to add custom routines, track upcoming water changes, and set automated reminders for equipment cleanings.<br><br>Smart Dosing Alerts: Plan your chemical dosing schedules directly through the quick-actions panel.

Evaluate future fish and coral additions based on specific dietary requirements, light preferences, and territorial aggression levels.<br><br>History &amp; Insights Terminal: Review your overall aquarium performance at a quick glance. Track your Best Streak of continuous logging, analyze tasks Done This Week, monitor Active Tasks, and get automated workspace safety statements confirming when your metrics look stable.<br><br>Calibrated Target Ranges: Customize your ecosystem&#39;s exact safety margins inside the settings panel. Manually assign minimum and maximum target thresholds for every critical parameter (pH, kH, Ca, Mg, NO3, PO4) or implement baseline reef-safe defaults seamlessly.
