Compact pump which is perfect for low volume aquariums. You can adjust the speed and the output direction. This is very useful when you have fish that do not like the current as combatants (unless you want to see die of exhaustion). The filters are easy to change and property (provided you do not put too decorations in the aquarium). It easily and does not move grip. The air intake helps oxygenate the aquarium a little but does not replace a pump that calms the fish. Easy care.
