This dual outlet pump really is quieter than any other pump in its price range. Perfect for deeper tanks and for rooms where a silent pump is needed. Features dual outlets to connect your airline hoses to. A switch is built into the four foot electrical cord to switch between high and low pump settings
Dolphin 1: Recommended for tanks up to 55 gallons in size.

Dolphin 4: Recommended for tanks up to 125 gallons in size.
I bought a Dolphin 5-Star to run two 30 gallon tanks. It does the job well but it's very noisy to say the least. The filter on the bottom of the air pump clogged quickly but after I removed it it has been pumping fine. The price was low and the amount of air this thing puts out is good but only if you can live with the buzzing.
I recently purchased a Dolphin 1 based on the positive reviews on this web site. Big mistake! The pump is extremely noisy compared to the Hagen Optima used on my 125 gal set-up. I would never purchase another Dolphin and plan to scrap the one I just bought in the near future. The pump has no problem generating air for two airstones but is just way too noisy.
this is a corection on my rating of these dolphin pumps sorry about the mishap
