Re: Help needed with pond design

Hi Volker, welcome. First of all, what do you want to keep in the pond? You say it's about 5000 liters and 65cm deep, that is quite shallow. You could consider digging down to 130cm for example and you would get double that, the pond would be more suitable for Koi that way. What kind of fish were ke...

Re: Membrane results with filter

Hey Frank,

Thanks for sharing your results!
They look really good considering you tested with the filter included.
I'm surprised you got the membrane Airlift to run so well with 20 litres of air.
This again shows the good efficiency at low wattage/ air per minute numbers.

Re: Multiple airlifts

I see. It should be fairly simple. There are various airflow dividers available that divert the airflow into multiple channels. You can regulate the flow individually with small valves. You should be able to adjust them and compare the flow on each Airlift by eye. I'm not sure if it will be benefici...

Re: Multiple airlifts

Hi,
As far as I know it should be possible. Using a 40W pump to run two Airlifts should yield similar results as using two 20W pumps.
I'll notify Marc, he knows for sure.

Re: Kicking things off

Hi, I'll update the forum again with some basic information on filtration and Airlift, so every new member will know where to start and what to look out for when using our Airlift system. There are some aspects that are very important for proper operation. Getting things wrong will easily result in ...

Re: Kind of output pipe

The water displacement should be the same, maybe even better as you say. The problem is that the water will escape upwards in every direction. This will make it impossible to use a T-piece to let excess air escape. Normally the elbow directs the entire flow neatly in one direction, you'd have to fin...

Re: Kind of output pipe

I have played around with version a since I don't really have a deep enough water source to properly use the small Airlift I have built.
As for output compared to a 90 degree elbow, I don't know how it will differ.
I am quite sure we haven't tested it like that, not officially at least.

Introduction to the Crielsieve, a revolutionary pre-filter!

While we focus on the development of Airlift technology, we are looking to improve every aspect of running a pond succesfully, with as little maintenance as possible. The filter is a very important aspect of any stocked pond. Keeping it clean can be quite a challenge. Most of us are familiar with th...

All current test results! Chamber + Membrane Airlifts!

Good day, Here you will find all relevant test results as measured by Marc, Gino and Guyke. All tests were done with Marc's quarantine pond test setup using an ultrasonic flow meter. The flow was measured at the inlet to the collector (not in the Airlift) to prevent inconsistencies due to air bubble...

What is an Airlift and how does it work?

Good day, In this topic I will explain the basics of Airlift, in particular I will discuss the types we like to use. What is an Airlift? An Airlift pump, in essence, is just a pipe placed vertically in a body of water. At the bottom the pipe has an air supply connected, powered by a compressor or an...

Kicking things off

Good day! I'm done studying for now, which means I have time to work on the forum again. Things are looking a bit empty and we have a lot of valuable information which still has to be added to the different sections. I will create the necessary topics the coming days, and make some small changes to ...

Re: Airlift above water level

Hello Fernanda and welcome. I'm busy studying at the moment so I can only leave a quick reply for now. You seem to want to use an Airlift system to water your plants. The main focus of the system we use here is a massive yield at low cost. Discharge head has to be really low. In this video you can s...

Re: The pressure chamber, cheap and good

Interesting, I'm not really sure how to imagine your outlets. It is indeed important to look at anything in your filter area that is causing drag, and try to optimise it without risking a big loss in bio filtering capacity. You seem to be quite serious with your project! If you want you can start a ...

Re: The pressure chamber, cheap and good

Hi Frank, Thanks for sharing these results with us! So you are running one Airlift, which gives 24.000 litres per hour, at an energy consumption of 22,45 Watt? Are you using four outlets? Since you specify 4 x 6000 litres per hour. This is a good result, considering the filter is also causing drag. ...
