Hi all
I have a Aquarium Air Pump ACO-008, 100 Litres/Minute air pump and its on its way out after about 11 months the air volume has droped to about half of what it used to be

I have seen this one and Im wondering if some one has got any coments or has used one

Thanks Gabriel

Do you really need 100L/min air? Let me rephrase that - Do you really want to spend $.63/day or $231/yr blowing air into your tank?

There's far more effecient ways to airrate your tank...

As far as airpump's are concerned, I highly recommend the PondOne range from Aqua.. they come with a 3y warranty and are designed for outside continuous use.

Thanks Mr Orange
ill check them out

With that amount of air and more I managed to get my trout trough summer and my tank water tem was 31c

No worries. I've found mine to be very good.

As for the air, once you hit oxygen saturation that's it, adding more does nothing... So I'm not debating the effectiveness of oxygen in the water, just that you might only actually require 20L/min to reach saturation and 80l/min is going to 'waste' for example. Another thing, you could increase oxygen exchange by increasing splashing for example, which would reduce the amount of supplementary air needed. It all adds up to $$$ in your pocket

Gab,
The aco serious pumps have a diaphragm on the piston. Also two small flapper valves.
If you search the forum a few of us have pulled them apart and posted pictures.
They can be replaced fairly easily. Yours have probably partially failed.

I think the PondOne range also put out more air for less power consumption. Do you know who in Perth stocks them at a good price?

Noisey, run hot as hell... and don't pump air much beyond 300-500mm...

IMO... not a patch on the electromagnetic pumps...

And I'm at a loss to understand peoples comments about such pumps running hot, and noisey...

I had an ACO-008, 12 outlet running non-stop for nearly two years into my trout tank... about 10 metres away from the neighbours bedroom window...

(Still runs, just decommissioned at the moment)

I have another (ACO-002) currently on the job at Bamarang.... that has been running for about 4 years...

I agree with Rupt on this one
Also brings to mind the saying something about a horse water drink you know what i mean

Hi all '
Thanks for your responses looks like I was a bit short of air stones was only running 4 x 50mm Ill buy another one a bit smaller this time like 85L and then try to repair this one for spare pump

Regards Gabriel

A 35Lpm runs about 8-10 stones...

I need to replace a Resun ACD 8800A battery backup air pump as the 240 v side died. Unplug the 240 volt power and it works happily on the 6v lead acid battery.

I've been looking at some DC pumps such as the HZ-035A and the ACO-006 12V DC Hailea Air Pump. Both similar, maybe different in size, but I want to know how noisy they are and how long they may last. The have a permanent magnet motor and a piston.

Any experience here??

ACO-006 Think air compressor noise level. Quite loud so for that reason I have only used it in emergencies.

Rick you can come and check mine out if you wish ,I have given all the air pumps away including my back up and it seems to be working well.

Just looking at getting an AC air pump and wanted to know how loud the ACO-02 is? Is the hum discernible from say 10m away?

I've got a pond one 12000 that runs pretty quiet (hear water bubbling noise over it!) but is really too higher power for my needs - wanted to get something with similar or lower noise levels.

Other thing I'm looking at is the Hailea V20 - would that be alot quiter than the ACO-02? Also is it easy to get replacement diaphragms and flappers for them?

Thanks
Matt

It depends a bit on what it is mounted on, but yes the ACO-02 is audible @10m if there is no other noise. A bit of wind in the trees drowns it out at that distance though.
