The pump runs very quietly and maintains steady airflow. I used it with my 300L tank and the bubbles are consistent. The included air stones and hose work well. Easy to set up and fits nicely in the tank.
Nicola Churchill –
Good performance for a small tank. The flow control helps me adjust oxygen levels. The rubber feet prevent vibrations. Only minor issue is the air stone needs occasional cleaning.
