came up with a not so Straken air pump barely bubbles! the Befestigungist auhc not easy, unless you it is attached to the side plate as the light / air effect but not as nice. If you attach it to the bottom you have to watch that is no gravel on the air hose, otherwise no bubbles come again. The light is beautiful and good to see, but not too bright. If you install it on the ground to see the bubbles of red, nice effect. Cable is also nice long !.
