Oase ProfiClear Guard Auto Top-Up System
Automatic Water Level Control for Ponds and Filtration Systems
The Oase ProfiClear Guard Auto Top-Up System is an intelligent water level control solution designed to maintain a consistent water level in ponds, filtration systems and water features. It automatically detects when water levels drop and refills the system to a preset level, helping to keep everything running efficiently and reliably.
This is particularly important in koi ponds and gravity fed filtration systems where water is constantly lost through evaporation, filter cleaning cycles and splash out. By maintaining a stable water level, the system helps protect pumps, filters and biological processes. As a result, it improves overall pond stability and reduces the need for manual top ups.
The system uses a precision sensor to monitor water levels and activates a high quality brass solenoid valve when needed. Once the correct level is reached, it shuts off automatically. Therefore, it prevents overfilling while ensuring consistent operation.
Intelligent Control and Reliable Performance
The ProfiClear Guard system is designed for accurate and dependable operation. The integrated water level sensor detects small changes in water level and responds quickly, ensuring your pond or filter system remains within the desired range.
It also uses a switching differential to prevent constant on and off cycling caused by minor water movement. This improves reliability and extends the lifespan of the components. In addition, the solenoid valve automatically closes during a power outage, providing added protection against overfilling.
Because the system tops up little and often, it also helps dilute incoming mains water more gradually. This can reduce stress on fish and improve overall water quality.

Choosing the right pump setup
When choosing a pond pump, the number on the box is only the starting point. Real flow is affected by head height, pipe length, bends, hose diameter, valves, UV units and the filter it is feeding. A pump that looks powerful on paper can lose a lot of performance if it is pushed through undersized hose or a restrictive run of fittings.
For best results, plan the pump, filter, UV and return pipework together. Use larger bore hose or pressure pipe where possible, keep bends sensible and leave enough access to remove the pump for cleaning. This gives the equipment a better chance of delivering the flow the pond actually needs.
UV sizing and maintenance notes
Oase ProfiClear Guard Auto Top Up System should be matched to the pond volume, flow rate and water clarity problem you are trying to solve. UV clarification works best when water passes the lamp at a suitable speed and the quartz sleeve is kept clean. If the flow is too fast, contact time can be reduced. If the lamp is old or the quartz sleeve is dirty, performance can drop even when the unit still appears to be switched on.
- Replace UV lamps as part of routine seasonal maintenance.
- Clean or inspect the quartz sleeve when water clarity starts to deteriorate.
- Match the UV to the pump and filter rather than installing it in isolation.
- Allow safe access for lamp changes and winter maintenance.
Good UV performance also depends on mechanical filtration. Removing fine debris before the UV helps the lamp work on green water algae more effectively.
