Review on 🐠 Aquatop AP-40 Air Pump for Aquarium by Kelly Haywood

Purchased to run 4 small air filters, 2 for 10 gallons, 2 for 13 gallons so you'd think something that could double gallons would be enough. Yes I know it's overkill but 2 will go to a larger aquarium I will only encourage good bacteria to grow. The pump is small, smaller than the Whisper Tetra 20 but much louder. I had no blisters on low power, barely 2 out of 4 on high power. The Whisper 20, intended for less volume, actually fed 3 out of 4. So I'll only keep it as an emergency reserve and have already ordered the Whisper 40 which should help.
