AQUANEAT® Electric Small Aquarium Air Pump 300GPH, for up to 200 Gallon Fish Tank, Powerful Hydroponic Aerator Pump with Tubing, Air Stones, Air Valves

For the price, this is great. I use it for my plant propagations, and the tubing doesn’t come pre-cut so I could make it the perfect length for my setup. Love that. It isn’t silent but I don’t think it’s that loud, it’s like white noise and doesn’t bother me. My partner has said it’s loud, but it is adjustable so if you turn it down it’s quieter. The quality of the actual stones are great too. LOTS of bubbles. **** In the pictures, the LEFT air stone is THIS product and the right one is a different one I bought a couple weeks prior. You can definitely tell that this one gives WAY more bubbles.

This thing works great! I have 3 of them and just ordered a 4th. It's a little noisy when the airflow is restricted or its turned up really high... but functionality wise its fabulous. Handles multiple sponge filters, not just airstones.

I’ve had it for a couple months now and the tubes never come off, it works great. Can be a little noisy but I put a towel under it and that helped.

Air output on pump performs well but it is kind of loud.

Somewhat loud and big. Works very good comes with lots of parts and tubing.
