The Bubble Maker can be installed quite easily and well dig by the broad base and the compact design in the gravel. The bubbles look good. It brings a whole lot of oxygen into the water. The bubble density but can be difficult to regulate, making the device actually is only suitable for larger and large pool. Even after I had re-positioned the part, it was still very, very loud. One has the impression that the aquarium the vibrations intensified. After a few minutes duration I removed the pump again annoyed. A pity, because apart from the noise seems the Bubblemaker to work well.
