I have an open aquarium, in which I always had to deal with scum. So I decided to use this skimmer. He hangs with me on a timer and is every two hours for 15 minutes. The water surface is permanently clear and although I think even two species of shrimp in the pool next to fish, I've never had problems, that an animal would have sucked. The only thing I find of improvement, is the attachment to the Aquarium. The device is fastened with three small suction cups on the pane. But they are too unfavorable - and especially at the unit - mounted that you have to remove the whole unit completely to eg wash the sponge. After the suction cups hold well at the beginning, my stay they always stick to the glass, the rest of the unit then goes off. At the very first attempt at detachment a first sucker me then einwischt and fell into the plant thicket of my pelvis where he now lives a peaceful existence. Then there were only two .... We'll see when a next will disappear. Hello Eheim * wink * A support as there are for example, for heater, would be a great relief here. Then the suction cups may remain permanently in position and the device would be seen less stressful and to place again.
