HITOP Powerful Aquarium Air Pump, Dual Outlets Aquarium air pump, Adjustable Oxygen Aerator with accessories, for 60-600L Fish Tank

Tried three different air pumps for aquariums. The first was very small and loud. Second was bigger and quieter. This pump is the quietest out of the three but the largest but not unreasonable of a size. Looks cool unlike the others which just look like something you should hide.Also the best air flow, can easily do a sponge filter with the setting on low with the two air lines into one. Can choose to split the line into two if your aquarium is larger and you want one on either side.Would suggest trying this one before any of the other name brand ones. The two other I had were name brands with a lot of positive reviews.Glad I took a chance. The reviews here helped as I tried the others already and wasn't satisfied with them. Will gladly take the increase in size of the air pump for the silence in exchange.For ones who are unable to decide just order this one and whatever other you are thinking about and send back the one you don't prefer. If you can't be bothered to send things back just get this and save the hassle.

I needed a small vacuum pump I could use as suction with a JBC Tools hot air integrated circuit pickup tool, for electronics work. I have modified the flow of this pump using guides on the internet to suck rather than blow. It does a great job at lifting components off circuit boards at less than twenty times the cost of the JBC Tools vacuum equivalent. The hard power switch means I can activate it without access to the mains switch, and can adjust the suction to be just enough to lift components with forcing them. I did use separately purchased aquarium silicone tubing though, as the supplied tubing was too thin and inflexible for my liking.

This really is a great package. 4W pump with plenty of power for long air stones or adding a splitter. Quiet, flow regulator, air stones, tubing, one way valves, suckers plus a very handy on/off push button.You really couldn't ask for more.I got the dual outlet model, which I put 2 x 60mm silicone tubing on each outlet to a Y splitter. I then come off that with single tube to a 4 way metal air flow regulator, and the one way valves near the top of the tank. I always super glue my tubing on also.TIP:Dip the end of tubing in hot water to help with tight squeezes.

This is the quietest air pump I have used, it arrived with everything you need to use it with an aquarium the tubing was easy to attach to the pump, I am using both outlets to run a sponge filter and an airstone in an axolotl tank I haven't altered the air flow but it is easy to do also there is an on off button to save unplugging the pump during filter maintenance or changing airstones.The only noise I can hear from the tank are the popping of the bubbles in the aquarium if I needed another air pump I would definitely buy this again.

My old air pump sadly quit recently and was making noises that did not sound very healthy, so it wsa time for a replacement. It didn't have to be anything fancy, or big, the tank is only 60l.I was at a friend's house a few months before and he had one of these pumps - I couldn't even hear it, so of course I ordered one as soon as my old pump quit. It is so quiet, barely a hum can be heard, which is great. The lights are a nice touch too, not exactly necessary, but it does look fantastic sitting next to the tank like a little glowing shark!It's easy to adjust the airflow on the back, and there's an on/off button too if you need that. Far easier than going into the cabinet to unplug for a short period. Output is good, I only need it to power a sponge filter so I connect the two airline outlet lines into one, but it could easily handle a bubble output too using that second outlet. It came with lots of accessories, none of which I have used yet. I may replace the pump in my 450l tank with one of these and will take advantage of the included airstones as it's purely decorative in that tank rather than driving a filter.

Having a large tank (300 litres) this is ideal with a double outlet to feed air to both ends of the tank. Controlling the output not only minimises noise also bubble splash on the tank lid.

Excellent product better than I thought

The media could not be loaded.  The pump works really well and operates two of my oxygen respirators so it is worth the price and I like the lights on the pump and style makes it look like a fish itself.
