Review on 💨 Danner Manufacturing, Inc. Pondmaster AP-20 Air Pump - 1700 cu in/min by Rachel Guzman

I have added 5 aquariums and need another high capacity air pump. I made a classic mistake by buying a cheap unit by purchasing a VIVOSUN 950 GPH 32W air pump. What mistake. On power, and more importantly, the noise level was acceptable at first, after a few months it became unbearable that I sometimes turned off the pump. We bought a Danner AP-20 pump and haven't regretted it for a minute. Yes, it's much more expensive, but it's more powerful than Vivosun and the noise level is very low. Save your money and buy this device instead and you won't regret it.
