I have Tetra Whisper AP300 ($68), Hygger 10W ($49) and this Eheim 400 ($45). Out of 3, here is my ranking: - Performance (high to low): 1. Hygger 2. Tetra Whisper 3. Eheim-Noise (quiet to loud): 1. Tetra Whisper 2. Hygger 3. Eheim-Price (from less to more expensive): 1. Eheim 2. Hyugger 3. Tetra-My favorites (biggest to smallest): 1. Hyugger 2. Tetra 3. Eheim It's weird that Eheim has 2 air vents, but if one isn't in the water, it can it will affect the operation of another outlet. (Maybe it has some clever feature to sense drag and automatically reduce pressure? Whatever it is, I don't like that feature.) I found that while I was the cheaper of the three, I wasn't the I got the results I wanted despite using Eheim all the time. Now my new favorite is my brand be Hygger.
