Tetra Whisper 10 - Not bad, Not great either.
on September 20, 2011
Got the Whisper 10 for my 12g aquarium. It's been working for about 2 years now. So the durability is great. I wish I can say the same about the sound it makes. It falls short from living to its name as being a "whisper." Albeit, it's not necessary loud either. To tell you the truth, I wouldn't have known any better because I haven't gotten any other air pumps rated at this size for any other tanks. So I thought that the sound this makes is expected for an air pump of this size. This is, until now. I just picked up the Hagen Marina 75 pump for my other tank and by comparison, the Hagen is virtual silent. That was my main thing for choosing another air pump, I needed absolute silence. I just don't know how a product like this Tetra can call themselves a "whisper" when it's contradictory. Anyway, still not a bad buy... I DO LIKE how this Tetra Whisper comes with an air control valve to fine tune the amount of air pumping in to your airstone (or whatever you have it hooked up to). Not a lot of air pumps come with one... so if you bought another brand, you might have to get that separately if you want less bubbles.
