![]() This can be replaced, however the shipping and cost is about the same as a new pump. The main component that breaks is the rubber diaphragm. If you take advantage of all of the above listed tips for reducing pressure then your pump should exceed the normal lifetime. The Tetra Whisper should last between one and three years, with many users going well beyond that. Clean one and allow it to rest and dry for a month before swapping the two and repeating the process. Combat this by having two sets of air stones/bubble wands. Air stones, bubble wands and air tubing can all deteriorate.Dust can create unwanted heat, shortening the pumps life.Mine is held in place by the silicone tubes. Securing the pump in place with holes in the stand is helpful. The pump may move due to vibrations, allowing the pump to find a much louder home.The vibration will also produce a fair amount of heat.Try and tighten them if you notice increased volume. The constant vibration can loosen the screws, increasing the noise generated by the pump.MaintenanceĪfter running for a few months, air pumps can create a few issues. I do not recommend keeping your pump like that, as it will shorten the lifespan of the rubber components. This did not help too much with my own pump and trapped a lot of heat. Some Whisper owners will advise you wrap the pump in a towel. You can get a similar result without it but I like my devices super silent. By cutting small holes and surrounding them with silicone I created a sound muffling box set, only supplying a bit of my own silicone. I used the amazon box that the pump came in as well as the tetra box. If you own betta fish this will almost certainly be a requirement as the whisper can be overpowering fro slow swimmers.įinally the noise can be cut down further by placing the pump inside of boxes. If you wish to power more objects the tetra whisper does work well with T-valves or gang valves. The pump does not have a flow control valve, however you can add your own inline valve for about $1. Be sure to keep the air stones clean, as trapped debris will also add unwanted pressure. Limiting the outputs will make the pump much more noisy, making large air stones essential for larger pumps. Pumps placed below the water line will need a check valve to prevent any reverse siphons.ĭepending on the size of your air pump you will need to adjust your air stone/outputs. If you have no where to store the pump above the tank, placing the pump below the tank is fine too. This creates an optimal set-up, allowing the pump to run with as little resistance as possible. Similarly try to use only as much tubing as needed, as the extra travel time will also increase back pressure.Īdditionally the pump will perform more quietly when placed above the tank. By leaving one open you create excessive back pressure, which will generate a lot of noise. First you will want to use all the outputs. There are however plenty of tips for the best air pump set up. Like most air pumps, the Tetra Whisper is plug and play. This is important as not using both outputs will result in a much louder air pump (Explained In Set-up). The two smaller size have a single output while the two larger sizes have two outputs. It brings a lot of power, often too much for beta fish owners, and offers a two year warranty. It is consistently quiet, when properly set up, and comes at a very friendly prices. ![]() The Tetra Whisper is the common starting point of most aquarists air pump, and for good reason. ![]()
