Lineba Adjustable Aquarium Air Pump 5W 2 Outlets Fish Tank Oxygen Air Pump with 2 Air Stones, 2M Silicone Tubes

Very loud, hose was very thin and pinched to the point that I couldn't use it. Returned immediately.

The air stones can get algae on them and produce less bubbles but with regular cleaning it all works great. The air tubes aren't too long in length and are a little flimsy but the price makes up for it.

Great product with the price

does what expected
