Veral omdat al jou damme verbind is kan probleme deur almal versprei.
Jy sal beslis na 'n aparte kwarentyn dam moet kyk volgende.

Ja jy is reg ... ek is besig om te kyk hoe ek so dam kan inbring. Probleem is die dam moet totaal afgesonder wees en dit gaan beteken a hele installasie of is ek verkeerd ?

Heeltemaal reg, 6000 - 10 000L werk goed.
Nie eens naby jou huidige damme nie.
Eie filtrasie pompe en nette.

Myne is sommer bo-grond gebou enkelry maxiblocks met bottom drain.
Sandfilter en Biobooster werk maklikste.

Hello almal, Colyn, jou projek lyk great.

JAco, ek is besig om self te beplan aan n nuwe koi dam by my town house so ek het nie baie spasie sie.

Ek kyk na omtrent die grote van jou kwarentyn dam. Ek wil my stem by Bubbles sin voeg, kan jy asb vir ons fotos & dalk planne van die dam hier op die forum plaas? Asook jou filter "setup" wat jy daarvoor het ??

Baie dankie.

Today is one of those days where I doubt everything I have done Sad

Here is a collection of shots that will explain better why I am in this mood ...

This shot is the stream that connects the pods. I have 4m between Pond #1 and #2 and 12m between #2 and #3

My questions are this ...

1. In what way can this be utilized to assist with the health of the water?
2. Should I place smaller stones or bigger stones?
3. The stream do run the risk of running dry if power should fail.

This is the first chamber at the end of the pond system.

This is the second chamber and the new 3rd chamber. The 3rd chamber was added because I need
more volume to store for the "transito" volume needed to get the system in balance.

Here you can see the start of a skimmer weir for pond #3. This pond is fringed by some trees
that are dropping flowers and leaves into the pond and I realised that I need a better way
to draw off surface debris. The skimmer will pour the water into two chambers and the
final chamber will spill into chamber one posted earlier.

Another view of the weir/sump/pit setup.

Current volume is not enough to cope with runoff when pumps shutdown.

This a view of a major design oversight.

In the last shot you can see what I did to strengthen the side that was above ground. The plan was that this will host plants on the pond edge. However, by pure oversight the edge was not raised and once the pond is full this flowerbox will be filled by overflow as the outlet is on the same level. Sad

Now I have some options with it.

1. Continue with the stonework and cut the flower box off from the pond. This is most probably the easiest and cheapest option.
2. Do the stonework to follow the outer edge and by that incorporate the flowerbox in the pond.

Option 2 will mean that I have to cast a proper base for the flower box and waterproof it. I will also need to pipe some sort of bottom drain into it so that I can draw water off to pond #2 to ensure that the water do not stagnate in the flower box. This box will not get koi in because the overflow is shallow and plants could be safe.

What will you do ?

Comments and ideas are welcome.

i would continue the stone work on the inner wall and still use the flower box with little higher plants and the streams i would say is good for a biofilter with some smaller stones

Subject: Re: Rhenosterkop Koiponds ... I have a vision Mon Jul 07, 2008 10:17 am

Thanks Eugen ... that is what I have decided on too. No need to complicate my life further at this stage.

This is going to be the major bio-filter element of the system.

My problem is now with the bio material. Damn the stuff on offer is really expensive and will cost me a small fortune to put into these tanks.

It is 1000 liter capacity tanks and I need to know how much bio-material per tank. I would also like to know about alternatives. I have been told that the following is options ...

1. 25mm pieces of normal electrical conduit tubing.
2. Plastic hair curlers.
3. Plastic bottle caps.
4. 25mm pieces of normal LDPE pipe.
5. Concrete stone.
6. Bundles of shadecloth.

Can anybody please chime in and give advice.

Thanks.

Hi Colyn,

As ek so na daardie groot tanks kyk dink ek die beste sal wees om "tuinslang" te gebruik.

Sny die tuinslang op in 25mm stukkies,
Plaas die stukkies in lemoen sakkies,
maak so 5 sakkie aan mekaar vas met 'm nylon tou.

As jy dit in die tanks plaas moet die nylon tou lank genoeg wees om oor die rant van die tenk te kom.
Maak die toue saam aan 'n punt buite die tenk vas.

Wanneer jy die tenk en "media" will skoon maak kan jy die met die nylon tou op trek, spaar baie kopseer en moeite.

Hi Colyn

Obviously the size of your tanks is a bit of a concern...because it will dwarf most of the filter medias...so the normal / standard filtration suggestions might not work for you. Another option that i have seen with tanks of those sizes before is to hang brushes on a cable inside the filter.

I believe that one should realy consider which media to use in a pond as it is going to be in you filtration system for a very long time and you are going to have to live with it.

Consider the following when buying filter media.
1. The surface area.
2. How easy to clean.

Have a look at this article which i wrote for KOISA a year or two ago. http://www.koiadventures.co.za/Home.aspx?Page=UsrGeneric.ascx&Rec=258

I believe in aerated K1 Kaldness because you never have o clean it and it has a huge surface area which means that you need less of it compared to other medias....but it is expensive +- R 700 for 50L. 50L of K1 can process 250g of waste a day. So 150L should do the trick for you i believe.

I have also tried "Plastic hair curlers" in the past but it works out more expensive than the Ultra Zap Bio Balls...

This company http://www.bioballz.co.za/ emailed me on my website the other - have a look at them. They advertise 100 units = R67.26 incl vat 1000 units = R513.00 incl vat which is not bad.

Have you thought about using Oyster shells? It will help to maintain the water and will also give a large surface area...

Dankie Pieter en Wayne ... ek het Bio Balls gekontak.

Probleem is dat Nelspruit nou nie so groot source vir Oesters is nie Wink

Ek sal die bio material in avosakke sit en met toue hanteer ... dit kan seker a issue raak om die goed uit te duik in daai tenks Smile
