Owners complain about
  • Can be finicky to restart after a power outage or once the impeller gets dirty, sometimes needing repriming or grinding/failing to cycle water at all
  • Outflow is quite strong out of the box and often needs configuring to tame, with a few owners removing it from planted tanks because it was blasting their plants
