Review on Filter AQUAEL Unifilter 750 UV by Dorota Janiec (Dorot ᠌

I wish the filter was quiet. I chose the ratio of power consumption to the number of liters per hour. Quiet, the compressor itself can only be heard if you put your ear at a distance of 20 cm from the aquarium. In the first 2 days it made a crackling sound, then each time the crack passed faster and disappeared. Probably the ceramic axle has worn in. There are fragile parts: my air diffuser is a little cracked, if you remove it, then carefully, twisting it a little to the right to the left. And the hook from the suction cups on which the filter itself is hung - it seems that you should not make unnecessary movements with it, although the filter is removed and put on easily. At the expense of the ultra violet, the water does not become cloudy from it. I believe that in the short period of time that water rushes through the lamp, it will not kill anyone. It just hinders the development of bacteria, both good and bad, for example, eye diseases in fish. I poured water under the stiffening ribs, so the bubbles burst under the glass (you can see in the photo) an order of magnitude quieter, although now large bubbles burst when they float out from under the glass, you need to put some kind of diffuser, smaller bubbles are not audible. and there will be no dirt and bacterial outbreaks in the upper corners. and the bottom of the ribs under water.
