Review on Efficient Aeration with Eheim Air Pump 400 by Wiktor Michalski (Li ᠌

because I turn it off at night and think about a time outlet :) Pros: He's really quiet, well, as much as possible. And very powerful, I have a 200l aquarium, I connected one outlet to both nozzles in the kit, the second to a special perforated hose (I bought this separately a long time ago) and now all the rear stacks are in beautiful bubbles :) Both krutilki at a minimum and generally enough. Different cons: I wanted to completely replace the air in the aquarium with them, but still this is only a daytime option for me, I turn it off at night. I sleep right next to the aquarium (1 meter). But in a new apartment, I think I will refuse air through the filter. Those. air through the filter is quieter than this compressor, but it is logical in general.
