Simply Koi and More Koi

Do it once do it right. If you want a window at all, you will regret not adding one later. Like I did on my current pool. Good job Im moving then

The cost is irrelevant when you think about now many years of joy you get from something like that.

Hi Jane Thats more or less what Im thinking of going with but with pipes through the wall and having a completely separate tank for the airlifts. Hi Al Mine will be fed from my Nexus 200 so I will be limited on how much flow I can produce. Will possibly only need 4 airlifts with possibly 2 FFs throw...

Hi Jane I like your design and it would work great I think BUT (why is there so many buts in my posts :lol: ) can you imagine if one of my fish swam/jumped over the top into the airlift area thinking the grass was greener on the other side? They could cut themselves to pieces on the pipes, unless th...

Hi Gordon what you propose works in principal as the water coming out of the airlift will always be trying to get to the same level as the filter/pond. BUT the amount of water I want to be pushing I think the water will not be able to return via gravity quick enough. All these questions/ideas will b...

Cant be a bad thing running that much fluid K1 even after the Nexus. Im contemplating having a fluid K1 Vortex after my Nexus 200 which will also hold my airlift pipes.

Then just have a static K1 vortex/or other filter design on the skimmer?

Thanks Al! great info as ever.

Glad Im not going mad thinking that the returns could not go under water, the filtration end of my pond should look something like this:-

Will have to find a way of making this look more attractive

Andy, thats what Gordon was suggesting but Im not convinced you can get the flow needed to circulate a pond at the same time as extracting protein/doc Gordon, Im not convinced that the airlift will work very well submerst, i.e. outlet under pond level. By that I mean pushing water up and out against...

quote from Larry Lunsford - "The best method of injecting air is to use air stones. Air stones provide the smallest bubbles which result in the best lift and aeration" BUT Im wondering about using small maxairs for this, causing much less back pressure on the air pump being used and theref...

Gordon, only just seen your diagram Problem with the airlifts being between skimmer and vortexes is that the vortexes would then be pump fed effectively and the 2nd vortex outlet would have to be above pond level. Secondly the foam fractionator idea built in wouldnt work for the amount of water I wo...

Hi Vippymini Are these the details you are refering to:- [url]http://home.netcom.com/~larry_l/air_lifts.htm[/url] http://aquanic.org/publicat/state/il-in/ces/ces-240_airlift.htm They are the links that convinced me this is well worth looking into. My plan is to carry out some tests once we have move...

Okay peeps Id appreciate your imput on this design. It is purely a quick draft of what I intend to do after a recent post got me thinking about using an airlift instead of a conventional pond pump. [img]http://i48.photobucket.com/albums/f208/GuyP/untitled.jpg[/img] BD will be gravity to my current n...

Hi Al Thats not bad then really is it 10-15% you never now I may go down the stream flow route. Lots to do till then though. Dont think I can fit the desired amount of pipes in my Nexus200. Think a vortex after would do the trick or a bank of them and have the nexus running on its own on the skimmer...

Thanks for the linky Al, great help!! Without doubt going to try this. The thing that put me off the stream flow was the amount of water being changed and what with moving next month I will be on a meter once we move. My main problem will be being gravity fed to Nexus and then air flow back to pond....

Thanks Diego! So it is possible. Has anybody else got any views on this method of moving water from filters back to pond? Im trying to think of the cons and the only thing at the moment is air pump reliability but with my secohs I cant see a problem with that really. Could just have one spare sat by...

I would love to hear an anwer to that question GDL... Im sat here thinking you could well be onto something there!
