View Full Version : Noisy AquaClear 500
Bill Stock
September 4th 06, 02:05 AM
My AquaClear 500 was sounding a little noisy, so I decided to give it a
thorough cleaning. I took the motor off for the first time in five years.
(Manual says clean every three months. LOL.) But now it sounds worse than
ever. The impeller looks fine, although the metal shaft might have been a
little worn. I'd say it's just a matter of time before it goes. I think I'll
just replace the whole motor, since I'm not sure it's the impeller. This
little workhorse certainly doesn't owe me anything.
Does anyone have any suggestions or has it's time come? Who knew fish poop
was a lubricant! :-)

I have an Aquaclear that sounds like a buzzy, grinding cement mixer for
ages. I wish it would die already because I can't force myself to toss out
a working filter.

might just be a little worn and so is 'wobbling'
the mulm may have been buffering the impellor
pretty cheap pump, grab another and use the old one for spares.
just move all the cycled filter media accross into the new filter
toooo bloody easy mate

There are no moving parts in the actual magnetic motor unit; it is rare it
has any sort of failure outside of failing completely.
Noisy AquaClears are almost always due to a worn impeller or impeller
shaft. The impeller shaft usually costs about $2.99 and the impeller maybe
$8.99. I would try replacing them in order of cost. I can almost
guarantee it will fix your problem.
If you clean your impeller as AquaClear recommends you can extend the life
of your impeller assembly.

I'm pretty sure it's the shaft, but I can't see how this comes out. It's not
ceramic like other Hagens, but metal. I was going to yank it out with the
pliers, but did not want to break it, in the event it's not removable?

That is exactly how it comes out. They are removable; it just sits in a
shallow socket. Use pliers, pull and twist gently but firmly. It will
come out.
The shafts are usually the culprit, but sometimes wear will build-up on the
inside of the impeller as well. If replacing the shaft doesn't eliminate
the noise, replace the impeller as well and your AQ should be dead-silent
again.
It is not uncommon for AQs to become noisy for this reason after about a
year of use or so if they are not cleaned regularly--even then they
occasionally become noisy anyway.

guilty benefit of a discount thru work
besides impellors often cost 2 thirds the cost of a new filter!! Well not on
cannisters and good sump pumps and stuff.
But powerheads and waterfalls the parts cost can be crazy.
shaft and/or impellor change would do it tho, dc is pretty switched on eh
what?!

I've got one where it appears the case and/or the top warped after a year or
two. Makes noise till I remove the top or sit it diagonally on the case,
then it's as quiet as ever. None of my other AQs have shown this problem.

The noisy top is due to vibrations caused by the impeller. If you go
through the same steps I proposed to the other poster I'm sure your AQ
would settle down.

Mine started to make noise in no time at all. I should have just returned
it for a refund or another AC. All our other ACs are silent and some are
well over 10 years old now. And yes, they still work! :-)

The shaft is all one part with the motor on mine. Only the impeller is
removable.

What exactly do you grab to pull it out? It looks all like one part with
the motor assembly.

I see impellers for sale but where does one buy the shaft for an AClear?

Thanks, the new motor came today. $29 CDN.
But I think I'll rehabilitate the old one in any event.

I found a whack about the head (lid) was useful. :-)

Unless you have one of those ancient AQs were the motor ran completely dry
and the impeller sat in a plastic well built into the plastic body of the
filter, then it is removable (I think they stopped making those in the
80's). All you need to remove it are pliers and a steady hand.

Just thinking of a the current 110/500 again... it does use a different
motor from the rest of the AQ line. I will double check tomorrow to see if
there are any differences in replacing the impeller shaft.

I had a look at one today. It functions exactly the same. Both the
impeller shaft and the motor are larger but the shaft is removed exactly
the same way as in the smaller AQs.
The one and only time I encountered the old style AQs was when my uncle
gave me his old aquarium he had running in the 70s. The motor connected to
the outside of the plastic case of the filter by way of two large clips and
it had no physical contact with water whatsoever. The impeller and the
shaft were isolated from the motor inside the plastic filter case.

Thanks. The next time I clean the well I'm going to see if I can grasp it
with a pliers and remove it.

Just be gentle; pull straight out while giving it a bit of a twist and it
should come right out. For some reason replacement impeller shafts for the
500 are harder to come by than the universal shaft for the smaller AQ
series.
