New project, will take a long time

Also the back pressure from 3 would force the media back into 1. I'm trying to get a picture of K1 for scale but my dslr is being fixed again and since I've had it getting a p+s to take a half decent picture is a real pain

How do you figure that the pressure in vortex #3 going to be greater than the weight of the water in the pond?, I think not. Even if your return tube(s) are at the ponds bottom. The water in the vortexes should level out without even overflowing do to being lidless, as long as they sit at or above water level of the pond.


As for problem (3) the media flowing forward into vortex #3, you can use what I believe is known as a Non Return Valve. And if you still believe that whatever the volume of vortex #3 is, could possibly hold enough pressure as to force water and media from vortex #2 into #1 and water back into the pond, then use one. I just don't see water running upstream without a pump. I cannot believe that the water and it's weight will give way to to the much much smaller volume of water in vortex #3. But what do I know, I don't live in the land of Moon Monkey's, where everything runs backwards.

You know you can always cover your pond floor intakes with DIY strainers made from eggcrate, large pieces of poo will pass through 1/4~1/2 inch opening but not big froggies.


Dude honestly can you explain to me why you went with this filter system setup and not with a pre-fab filter system or a Nexus free flowing media/vortex filter or a modified pool filter. I just don't understand why you gotta make things hard than what they need to be.


Dude all one has to do is google "k1 media for vortex filtration systems" and you can see the sizes K1 bout half the size of a penny, K3 a bit larger than a penny. Except I don't see that blue/green stuff you use.

I'll explain later, I'm running late for work. Just a quick point a nexus goes for about £1100, DIYing a similar filtration system costs a considerable amount less

Ok just curious what this diy filter has cost you in energy, time and monies?, and just remeber it still isn't up and running. Also remember that while the Nexus may cost a small future, there where other choices that cost much less that are either pre-fabs or still along the lines of diy pumps, pre-filter, plumbing and filtration units. I found a pre-fab unit for about half of your stated Nexus Price, that has one vortex built in.

I'm sorry dude I just don't see the advantages of this multiple vortex system you put together. I thought that the reason behind the vortex construction vat was to have the media in the vat moving in a circular motion suspending the media so that the full surface area of the media was utilized along with large debry seperation etc., So why then do you have three vortexes, with only one running suspended media?

Any who, did you find figure out a solution to problem (3) yet that you can do easily enough? I'm not sure at this stage that you can just pop in a Non Return Valve, because I believe you already cemented the piping together.

I think you've misread somewhere because what your saying is right?

A non return valve would sort of ok but I can't install one and if I could media could still pass through to chamber 3. As for media going back I've mislead you, since I've changed from a submersible pump to a static this no longer an issue.

But then how do I fix it in?

Cost saving and a I like a challenge, plus things can be changed along the way and added to later which using a prefab model it can't. Plus where would the fun be in just buying a nexus and switching it on

I thought you were too lazy, even for google

Proper system test, 24 hours on and running through the UV. The floating skimmer clogs after about 24 hours with all the algae etc in the pond, it's got 2 tiny sheets of jap matting as a filter on it, with a flow rate of about a year to cycle the pond. I've fired up the big system with 8 pads(4 full sheets) of the stuff, full pond turn over in 1 hour 20 to 1 hour 30.

It's time to stop worrying about the frogs etc, and just see how this stacks up. I'm not even going to look at it when I get up, just go to work and see how things look Sunday morning. If it's clearing up then I'll sort out the chamber flow problem and leave it like this for a week and then fire up the fluid bed, 100 litres of K1 on stand by

Apparently skimming catalogs and google makes one an expert on ponds.

Yeap Mrunlucky you found me out that's how and where I know everything I know from. Including how to get out of bed every morning.

Wow, I guess I should list my resume next time I ask a question of the guy running the thread huh.

What I meant was, with the old pump when I switched it off the water from the pipe went back through the pump to from where it came forcing the water through back through the system for 10 seconds or so, not the case now

Ok glad you cleared that up!
