When it comes to adding air to many aquarium tanks, there are a few options available with large air pumps.
The typical aquarium air pumps will have outputs of 1,2,4,6, and even 8, but how can you connect additional devices without requiring a slew of splitters?
Large high-flow air pumps suitable for connecting 100 or more devices are available.
The manner you connect these pumps will also have an impact on the results. A manifold is typically used when a set of devices or tanks are in close proximity to one another. A manifold will allow you to connect the air pump directly to the devices.
The issue with manifolds – When connecting manifolds, 4mm airline is used, which is OK if all the devices are close together, but if you have to run meters and meters of the airline, the pump has to work harder to force air through smaller tubing over longer distances, which is not ideal.
Making use of the loop. – The option is to create a loop, which may be done using PVC tubing or even an irrigation hose. Using irrigation or PVC and linking it into a loop or figure 8 allows for equal air movement throughout the loop. You may then use an airline to connect straight from the loop to the gadget or aquarium, which is more efficient than a manifold and allows you to connect additional devices or tanks in 90% of situations.
What to be wary of. – Back pressure occurs when the quantity of air generated is not released, causing the high flow air pump to work harder, heating up, and limiting the lifespan of not just the unit but also the diaphragms. You can relieve back pressure by simply letting the built-up air be discharged, which you can do by opening up a couple of airlines, but be cautious since too much will result in insufficient air reaching the devices and tanks, so retain the balance.
Why is there no or insufficient air – The most common explanation for insufficient air is a simple one.
There is an open line, often known as an air leak since air will choose the shortest way to depart through an open line or aperture.
There is an issue with the diaphragm, which has to be replaced (diaphragms are part of maintenance and should be updated on a regular basis – it’s a good idea to have a spare set on hand) or the pump is just too small.
How to Choose the Correct Size – It is difficult to provide a clear solution to the topic of how to choose the correct size. As a general rule, when connecting the loop on a 30cm deep tank to a single airstone or sponge, you’ll want 1 liter each minute – what is 1 liter per minute? – At the bottom, there is a YouTube video that explains what 1 liter per minute is. If you utilize airbags, you will require more air provided to them and will be unable to connect as many; similarly, the longer the lengths of the airline and the deeper the tanks, the more the units will have to push, reducing the number of tanks.
