Rated 5 out of 5 by Landlubber This is the one
I bought the AP-4 and I am very pleased with the product. It has two outlets and features very easy to use air flow control. This is great if you need to provide air to multiple tanks. This pump is powerful, yet surprisingly silent. The quality is great and has an unbeatable price! Another great buy from Drs F and S!

Best pumps for the money and then some. I have many tanks and use the Danner 4 or Danner 8.

Rated 5 out of 5 by Cichlidman63 Excellent air pump.
I purchased the Danner AP4 six months ago. Overall I would say this is an excellent air pump. Its features vs price makes it an excellent value. On most of my tanks I have another brand that is blue and black and has 4 legs. Looks like a walking ashtray. The Danner beats it hands down in noise looks and above all performance. As the other ones fade. They will be replaced by Danners.
