    Default Tetra Whisper air pump not working properly

    I just bought a Tetra Whisper air pump for my 2 sponge filters in my 55 gl tank and noticed that the sponge closest to the air pump is getting all the air flow to it. Any idea what I could be doing wrong? The other sponge gets some air flow but nothing compared to the one side. Any info would be greatly appreciated.

    Thanks, Aram

    Is this a two outlet model or a one outlet model and you have a splitter to make the one outlet feed two sponge filters?

    Yes, it's a two outlet model and no I don't have a splitter.

    I pretty much disassembled the entire pump to check for any blockages but didn't find any I also replaced the air lines. I tried switching the air lines to test each output and they would continue doing the same thing, only 1 side getting 90% of the air flow. I'm all out of ideas.

    I run pumps like that to a adjustable 3-way gang valve. I'll have the pump go in at the in port, and one of the "out" ports. And I then just adjust the outlets to the airstones to a balanced level.

    I run a couple of these in my fishroom. Had similar issues, all of a sudden stopped working when it was not very old. I sent it to the manufacturer and they repaired it and they have been great since (couple years now).

    You're running one pump outlet to one sponge filter, and the other outlet to a second one, right?

    Switch the hoses at the pump. If poor output switches at the sponge filters, the pump is defective and should be returned. If poor airflow stays with the one filter, then there's a problem in that circuit.

    Probably the best way to use a dual outlet pump, once you have a good one, is to run tubing from both outlets to a manifold, like this-

    Then run tubing from the valves to the outlets in the tank. I'd recommend a 4 or 5 valve model, so you can add devices as necessary, also vent off excess pump production to extend pump life.

    Scrap that tetra pump and buy hagan maxima pump..you will have too much air flow to know what to do with..buy a repair diaphram kit while you are at it...you will be totally satisfied with this pump..

    Yeah, one of the diaphragms are bad. I usually just trash em when they do that, unless it's a high quality pump. I like the metal housed, creamy tan colored ones that JEHMCO sells. I have one of the larger 20 LPM models on my 240 gal. that runs one, 2 1/2" airstone in the tank, (valved down) and 6 smaller airstones on the bio reactor that "boil" the water in the sump without a problem. It's quite as well. Good pump.

    Josh, why don't you return it for cash and buy a quality pump?

    Did you open the pump up and check the rubber diaphrams? I have a Tetra 100 that had both of the diaphrams good bad, so I'm e-mailing Tetra for replacement parts. If they don't provide them for free, where can I get the parts?
