Review on Efficient Aeration with Eheim Air Pump 400 by Danuta Popardowska ᠌

Some pros: Excellent compressor. Has 2 outlets. Connected a ceramic atomizer -70 cm. I use it in a 450 l aquarium. There is a regulator of 2 pcs of air supply through the channels. Excellent brand. Not cheap, but worth it. With its cons: "Excellent" compressor burned out after 3-4 months. It is not clear to whom to return it. I do not advise to buy. Noisy, definitely. There is something to compare. For such money, such junk.
