I just installed a small pond of 155 liters, IM filter cascade Weir how to get a pump that I need. thanks
The golden rule for aquariums is to drive the content of 4 times per hour, so it needs about 600 liters / hour or more if your pump to inflate more than a few feet. In the height of 4 feet, its pump discount rate of approximately 20%
