Hi all

I have reused my fishtank and the air pump isn’t working.
It used to work ok and make some bubbles but not any more. It appears that it only manages to get the air in the few first cms of the tube.

Any idea?

Cheers

Have you got the one way valve the right way round?

Kinked air tube?

Show us a picture when you’ve finished!

It’s a CFHproof pump just one hole in it.

Kinked air tube?

nope brand new one, but the reminder might get use for kinnky purposes 😉

It’s done I have 3 fishes inside 😀

Nemo will have put a small stone in the spinning wheel, swum up the pipe in a bid for you to clean the tank and escape over the road into the harbour……..

LOL at rich
no no nemo in my tanks only proper dumbass gold fish.
Plus the air pump is outside the tank.
I can see nemo go all the way through the 2mm diameter pipe 😉

You have to refill it with the special air they sell down at the pet shop.

The rubber thingy in the pump is split or has come adrift. If its a reasonable one you can probably get a parts set incuding rubber thing, filter etc.

I am sure you have checked, but is something covering the intake?

muddy_bum thanks I’ll have a look tonight 😀

Mudddy is most likely correct, the rubber diaphram has split. You can get replacements.Pumps are easy to take apart.

Is the pump humming?

If it is (as mentioned) the diaphram might be split or has jumped off it’s housing.

Check the air intack filter isn’t blocked (dirty), if it is take it out intil the pumps been serviced.

If it’s powering an undergravel filter you’d be better off fitting a powerhead on the tube for more power and silent running.

Like these

As above take the airhose off the pump and check that the pump is producing any pressure – if not the rubber diaphram is the likely culprit. If it is pumping air could be yourair stone is clogged. Try blowing down the line to see how much pressure is needed to make it bubble.

ok I’ll dismantel the pump tonight I kinda get got in a chainof events yesterday so I did not went back home.
I did blow in the tube (brand new and so is the bubble ball) and I there is some air coming on the other end.

I’ll see what I can do tonight

Cheers all
