Review on Efficient Aeration with Eheim Air Pump 400 by Ognian Atanasov ᠌

The photo shows an old-style compressor, they sent a new one. In my opinion, the old one is much more interesting due to the side rubber bands Pros: Excellent compressor, powerful, freely pumps large volumes, you can install non-standard atomizers Has some cons: Noisy, even if you put two check valves on one channel. Eheim also stood before him, but at 200 liters it was not audible from the word at all
