All four ports are always open, and the airflow can be adjusted using the dial on the top of the pump. If you only require one port, a smaller pump may be more appropriate.
I'm not sure where I got the figure of 9 liters per minute. However, according to the product description, it can push 275 cubic inches of air, which is equal to 4. According to the math, it pushes 51 liters per minute of air. Air at a rate of 19 gallons per minute.
The answer is contingent on the characteristics of the air (examples: Aerating Ornaments, Protein Skimmers, and Under-the-Sea Airstones are all examples of regular airstones. bubbler or gravel- Filters of style). 40518 AP- AP- AP- AP- AP- AP- AP Because it has four outlets and can push air to a depth of four feet, the number eight should provide ample aeration. 5', which is greater than most 29-footers' depth. Aquarium tanks with a capacity of 100 gallons and a depth of 18 inches. The rheostat knob on the top can be used to adjust the output to all four outlets to reduce the amount of air.
There is a loop in it.

This air pump is fantastic! I purchased a 7Watt 4 outlet. When compared to other pumps I've purchased, this one is quite quiet. I've suspended it in mid-air, and you can hear a slight vibration in complete silence, similar to when a window fan is turned on. Running on MAX in a four 5-gallon bucket hydroponics system, this pump is pushing those bubbles up and you can hear them popping. I'd go with 2" airstones because the 4" ones only push bubbles from the top portion, which isn't enough to matter. I'd purchase it again.
In my 75 gallon tank, I have this air pump. I have four Hydro Sponges connected to it, and the air stones never clog. To avoid bubbling noise, I use air stones, and this pump provides plenty of air to each sponge. This pump is set to the highest setting, resulting in a low hum that is barely audible. The pump itself is actually quite quiet. br>The amount of air supplied to each sponge filter is ideal, and I run it 24 hours a day, seven days a week.
There will be no issues. For an air pump, it's unusually quiet. We have a number of these pumps, each with four air outlets. We use suspended air to power our pumps. When compared to other pump designs, the noise (60-cycle hum) is relatively quiet when mounted this way. They haven't caused us any problems so far. We had a bad experience with small "aquarium air pumps," which were noisy and broke down after a few months. We recommend this to anyone who is trying to use a small aquarium air pump for hydroponics, as this larger pump will provide significantly more air and last significantly longer.
Well, I didn't realize that the depth of the tank, as well as the placement of the pump beneath the tank, would necessitate a lot of power. As a result, I bought it. I ran air line tubing through three ports, two of which had valves turned off, and one of which went to the sponge filter. There are a lot of bubbles produced by this. It hums a little, but I haven't noticed it in over a week.
The four-outlet air pump could only adequately aerate two of the buckets, but not the other two. It no longer aerates in the other buckets after a short period of time has passed. Not pleased: (Also, the air flow does not appear to be altered by the dial. ) br>The two outlet pump is excellent and I would give it five stars. The dial does not appear to work, but that is acceptable given the amount of air it pumps out.
man. okay. br>Affirmatives: It has a flow control system that can be adjusted. br> Though there is a significant difference between the highest and lowest settings, there isn't much of a difference between the middle and lower settings. br>If you're going to run smaller airstones or small-scale tests, This should be sufficient for medium sponge filters - however. br>Contrary to popular belief, there are a number of disadvantages to using this method. br>In order to get a good enough flow to power the number and type of things I was running, I had to use a'T'splitter connector and connect with additional air pump(s).
IT. IS. SO. FREAKING. LOUD! br>Gets extremely hotbr>br>If you're looking for a pump to use in your bedroom, this is not the pump for you.
This was purchased in order to eliminate the need for multiple pumps. The pump functioned normally on day one, but on day two, the first outlet became noticeably weaker and more noticeable when the pressure was reduced. I tried a few different sponge filters, but they all produced the same result. It's also louder than the ones it replaced. I like the idea of only having to use one pump, but after only two days of use, I'm afraid I'll be replacing it in a few months. Better yet, I may return it for a replacement, but I'm hoping nothing else happens. I'll wait a week before making a decision.
Big, strong, and eerily silent. br>br>Edited on September 13th, 2019- I really like it. I can not hear it in its cabinet at 80% (and that is all I need for my corner matten filter) br>9/6/20 EDIT- Still working on it. In the last year, I've lost some power. It sits a few feet below the 40gal, so there's no reason to complain. I'm not sure if it's gotten any louder. My tubes have a tendency to pop off from time to time, but this is most likely due to the fact that I am using the wrong type or size.
