Danner 04540 Air Pump: Enhance Your Aquarium's Oxygen Levels with 2900 Cubic-Inches Minimum Air Volume Review

So far it's doing a great job! I use it to break the surface tension in a water bath for a horse to keep it from freezing. I built a covered box to keep it dry and it still runs 24/7 in the cold. I don't know how long this will take, but we'll see. Don't buy local recommended hose, it won't fit, check hose size first. So far it looks like a win.

I had an existing Danner pump that had expired. It really never lived up to expectations. I really had to put up with it to make it work. I called Danner or the supplier about the problem and it looks like she went deaf. I still have this piece of shit. However, this new pump blew my doors open. It delivers at least 20 times more airflow than the original air pump. Enough air to water the pond ten times more than mine. In addition, the water is crystal clear.

It pumped out enough air for 55 gallons, 3 x 10 gallons, 2 x 20 gallons and I still leave 2 ports open on my manifold so I don't blow out the fish. I have 10 large tilapia foam filters and a large air stone. Has been working flawlessly for 3 months. It's quiet here, maybe not quiet enough for a bedroom or where you watch TV, but in our finished basement next to a new running air conditioner it's barely noticeable. I would say it's definitely quieter than the air conditioning in a hotel room…

My 2600 gallon carp pond does very well with it. I have 4 large cylindrical shaped pneumatic rocks that I purchased from this site that are attached to frost lines. Yes it does make some noise but not as much as I've read in other reviews. This is a pretty strong pump by design and feel so I expect it to last a while. Bought to save a hole in the ice after my Aquascape 4 outlet air pump half died (2 outlets stopped working because something broke in the pump). ). I sealed everything except 4…
