Great power...running in 50 gallon tank on 2 12" bubble bars.
Very strong for the size, quiet running, won't know it's there. Would recommend it for a large deep tank or if you have a long airline run. Would also suggest picking up a spare DW96 repair kit. You will eventually use it.
I ordered this air pump for my 125gal. Freshwater fish tank after the failure with the Rena Air 400. The bubble wand in my tank buried under the gravel along the back wall and Rena is too weak to make a bubble wall, bubbles were weak and there wasn't much of them at all. Whisper AP 300 is $20 more but it does an outstanding job, i even have to adjust the bubbles now because you can't even see the background behind the bubbles wall it makes. I'm happy with the result.
I love this air pump. I have a 55 gallon tank, with an underground filter system. I ordered an air pump designed for 100 gallons thinking it would be more than I needed. However, it was not at all near powerful enough for what I needed. I then ordered this air pump fit for 300 gallons and I tell you it runs my four underground filter outlets excellent. A little expensive but well worth it to have a clean tank.
This is a great pump! I used to have the previous version years ago. To give an example of what you can power, I hooked it to two 36" long "bubble wall" stones in a 22" deep tank and it overpowered them. I had to pump it through a manifold so that I could bleed some air out to make the amount of bubbles coming up look better. My only complaint is that when I bought this pump I wanted to order the rebuild kit at the same time since I'll need it eventually, but it was and still is out of stock. Ordering both at once would save shipping costs.
My dw96-2 has pushed a solid wall of bubbles through a 36 inch wall 2 feet deep for 10 years straight. I'm just getting a rebuild kit for the first time.I tried other pumps that couldn't come close.If you want high airflow in a deep tank, then this is the way to go.
