fish tank water level decreases

This SR01 aquarium filler solves the trouble when fish tank water level decreases continuously. Equipped with separate low & high liquid level sensors, it automatically turns on the pump to replenish water as soon as the water level falls below the set threshold, and cuts off power when reaching full water level. Anti-jitter processing prevents misoperation caused by water surface fluctuation, with 1-hour dry run protection to extend pump lifespan, suitable for freshwater, saltwater reef and planted tanks.

• Auto Water Refill Once Fish Tank Water Level Decreases

  Independent low-level sensor monitors water volume in real time. When fish tank water level decreases below the preset threshold, the pump will automatically activate to replenish water; the high-level sensor will shut down the pump immediately to prevent overflow, keep water volume constant 24/7.

• Dual High & Low Level Double Safety Protection

  Dual probe dual monitoring structure. Low probe responds when fish tank water level decreases for auto refilling; high probe limits maximum water level. Double protection avoids overflow and filter water shortage caused by continuous water evaporation.

• Intelligent Anti-Shake De-Jitter Function Prevent False Trigger

  Built-in signal anti-jitter logic. Tiny ripples generated by filters, wave makers will not trigger the pump mistakenly even if fish tank water level slightly fluctuates, ensure accurate response only when fish tank water level decreases obviously.

• Multi-Color LED Indicator Visualize Working State

  Slow green flash: auto refilling triggered as fish tank water level decreases; steady green light: normal water level; fast green flash then steady: water full; red light for power indication. Red light rapid flash alarm when pump runs without water for a long time.

• 1-Hour Dry Run Protection Avoid Pump Burnout

  If the low-level sensor keeps detecting no water and the pump runs continuously for 1 hour after fish tank water level decreases to zero, the device will automatically cut pump power and flash red warning light, effectively protect pump from idle burning damage.

• Complete Installation Accessories & Wide Aquarium Compatibility

  Comes with 1.8m PVC water pipe, fixing bracket, check valve and user manual, clip-on installation without tank modification. Compact size fits freshwater tanks, saltwater reef tanks, planted tanks and breeding tanks, stable water level reduces aquatic organism stress.
