This SR01 auto water replenisher perfectly maintains stable fish tank filter water level. Equipped with separate high/low liquid level sensors, it auto starts refilling when filter water level is low and cuts off power once full. Built-in anti-jitter processing eliminates false triggers from filter flow ripples, plus intelligent pump dry-run protection, ideal for all aquariums with filtration systems.

  Slow green flash: refilling water for filter; steady green light: normal fish tank filter water level; fast green flash then steady: water full; red light as power indicator. Red light quick flash alarm when pump runs without water.
