Hi guys, Neville asked me to help with a poll on sand filters because he is busy with an article on the subject. Please participate.

Hi All,

Thanks for casting your poll, for your information we are now at this stage.





This is the results after a 1,5 minute backwash, using approximately 300 Lt of water. I am hoping for even better results as a further mod is coming up.

What is this experiment about? What mods are you undertaking? This is very very interesting.

Hi Chris

I am not yet finished with what I set out to do, you know things change as one goes along. There is still one improvement that we would like to test, before I put my cards on the table.

We just want to make sure that the improvements will be unquestionable and worth while to all koi keepers, those with and those without sand filters.

Our problem presently is that the filters don't get dirty enough this time of year and we don't want to induce dirt it has to be natural.

Don't worry we will keep you informed as we progress.

En jy kak Pieter uit omdat hy jou nie die naam van daardie ander koi wou gee nie!! Nee man Neville

Chris,

Ja.............dis tyd dat ek sy kruisbande knip!

Moet by se as ons dinge uitwerk, gaan niemand nooit weer sand filters hoef oop te maak nie!

Nou gaan kak al twee van julle dan..... Ek sal maar hierdie kant 'n emmer om my nek hang om solank die kwyl te vang.....

Julle moet my maar PM as julle enige hulp of raad nodig het. Ek & my vennoot (ook Pieter) maak & versprei fibreglass sandfilters. Van 1 sak - 5 sak. Ons kan mekaar miskien help

Hi,
Interesting -

Neville - you need to know pond volume and pump capacity. This will tell you if the sand filters are being used correctly and if the pump is capable of back washing a sand bed efficiently.

You also need to know if two or more sand filters are used if they are used in parallel or in sequence.

Chris

Hi Chris,

Your fibreglass sand filters that you make. Have you tested the shell to take the pressures of swimming pool pumps and clogged sand beds?

Does your sand filter expand and contract when the pump is switched on and off?

Chris

Hi Chris

Thanks, yes I am still getting my act together here and will certainly pay you a visit before I finalize my story for some technical info, if you don't mind.

I am just trying to make sand filters a bit more popular.

Do you realise that William from Happy Koi is probably having a seizure when he reads this, he may even develop a nervous twitch .....

Chris, I sent your questions to Pieter. I'll let you know when he comes back to me. He destributes the filters to swimming pool shops throughout SA. I'm using them on my ponds and they work well. I haven't noticed them expanding or contracting when pump is switched on & off so the answer to that one is no....

Dis hoog tyd, kan nie wag nie.

Hi all,

Thanks for your positive postings, I enjoyed it very much, and plucked a lot of encouragement from it.

Fortunately today I can say, "YES BOYS IT WORKS". It is now a pleasure to clean a sand filter, can't wait for the damn thing to get dirty.

I did the last test run today and had as critique,s, the Honorable Sand filter king and Cliff also paid a visit.

I will post some more Pic's. Just pushing that bakkie shower now.

was very impressed watching how this new setup works.......very simple modification yet hugely affective.....cost to implement not too bad either, and with the amount of water you will save on your bill, the return of investment will be seen within a few months.

Neville, well done, will be looking into doing this mod by the time summer comes along.

Bet this is killing some people....lol ....those details are for Neville to divulge....sorry
