Early Detection & Control

- Action-first drift guidance
- Dosing trend deviation detection
Die meisten Riffprobleme beginnen unbemerkt.
- Alkalinity slowly drifts
- NO3 rises while PO4 reads zero
- Volatility increases before visible stress
- Dosing no longer matches consumption
By the time you see damage, the drift has already happened.
Why reef keepers move to PRO
- a fuller workflow from test logging to action
- stronger stability and history context
- AI insights, reminders, and dosing tools in one place

Hidden alkalinity drift
KH velocity change is flagged before threshold breaks.
V
Volatility spike before instability
Parameter variance surge is detected early in the cycle.
D
Dosing trend deviation
Consumption vs dosing trend diverges before visible imbalance.
