Awesome need more
My first one of these pumps died after about 4 weeks, but I brought it back and the Co-op replaced it right away with no problems. The second pump seems to be working great.
I have both the AP50 and the AP100 on 2 different tanks. They have great output while being able to adjust. Also, not too loud. Would buy again!
Compared to other air pumps I have, they are loud and a bit... whiny.
Great pump for the price. Not noisey in my opinion.
