Features

• 【Dual-Mode Upgrade】This product offers dual-mode functionality (Auto Top Off & Auto Drain) by simply adjusting the float orientation. As an Auto Top Off System, it monitors and refills evaporated water daily in saltwater/freshwater tanks, ideal for travel/holidays. As an Auto Drain System, it maintains low water levels to prevent overflow during heavy rain, ensuring tank safety. Switch modes effortlessly for diverse maintenance needs.
• 【Enhanced Water Pump】The upgraded water pump delivers a vertical lift capacity of up to 2 meters, significantly enhancing water circulation efficiency. Equipped with a built-in low-water level warning light, it provides real-time alerts and automatically shuts off when water levels drop critically, effectively preventing dry-running damage to the pump. This fail-safe mechanism extends the pump’s lifespan while reducing energy waste.
• 【Broad Compatibility】Unlike optical sensor that frequently malfunction due to limitations like aquarium glass thickness, surface dirt, or material opacity, this device utilizes a universal level sensor unaffected by tank/sump material, thickness, or water clarity. Its adaptive design guarantees reliable performance across diverse setups for all aquarium systems. The sensor’s minimal maintenance requirements and resistance to false triggers make it ideal for long-term automated water management.
• 【EASY INSTALLATION】①Choose the function that you need to drain or fill water (you can only choose one of them), and then put the pump to the place where you need to drain or fill water. ②tie a counterweight block at the bottom of the level probe with a thin rope, straighten the line and fix it at the designated position(Note:The purpose is that the water level probe will not be affected by water, and only the floating block on the water level probe can move freely with the water level).
