Hi -

Here are two interesting pictures.

The first picture shows the solid settlement inside Multicyclone. A day or two after start up a few months ago.

The second picture shows the solid settlement inside the Multicyclone a day or two after a good dose of bentonite clay into the pond - note the clumping of the solids.

Further report on the multi cyclone - really working well. Money well spent. Water clears quickly after rain. Never clogs. Easy to flush.

Hi Chris
Will you please post a picture of installation, is this installed directly onto a pump?

Hi Bobby -
Installation as requested

Multicyclone is installed after pump but before and biofilter or other mechanical filter. It can be installed directly onto the pump or on its own stand.

A good idea when installing is to have a valve immediately after the multicyclone. Close this valve, open the outlet valve on the multicyclone, turnon pump to get full blast of water to flush the inside.

Directly onto pump

On its own stand between pump and biofilter

Some more info for the techno boffins - also from the brouchure -

The filtration efficiency of the MultiCyclone was tested by feeding 5 to 80 micron dust particles through the MultiCyclone and analyzing the percentage dust particles trapped in the sediment bowl.

The laboratory test below revealed that the MultiCyclone was effective in filtering particles sized 40 to 80 microns.

DE powder was passed through the MultiCyclone to discover its effective flow rate.

At 50 litres a minute, the MultiCyclone was able to remove approximately 60% of DE powder and at 350 litres a minute; the MultiCyclone was able to remove 80% of DE powder.

Thanks Chris
I could possibly make installation no 2 work on my new system but the real question will then be the minimum size of pressure pump. Would the small yellow Ultrazap pump work?

Did you ad the montmorollonite clay direct into the water or did you mix it with the food?

Hi Bobby,

I am not familiar with the yellow Ultra zap pumps. But as the multicyclone was designed to work with swimming pools I would imagine you have to check the specifications and push of the ultra zap. There is a multicycone specification pahmplet available directly from them on theri web site. Alternatively I have th eemail address of the designer of the Multicyclone.


Hi Pieter,

The bentonite clay was added directly into the pond. Its interesting to see the way bentonite encourages clumping of solids. This is good for removing fines from the water.

Your ponds look great and don't really need this as they are very, very clear and have a sparkle to them not many koi keepers achieve.

If you do add the bentonite clay to the pond let us know if it makes a difference after a day or two.

Regards,
Chris

Hi Chris,

Thank you for the compliment! You and I Know it is achieved by using sand filters correctly, but please don’t say anything to the “Lazy Bunch.” Wink

In the beginning I also ad the clay direct to the pond water, but I found that it causes the sand filters to clod-up quicker then normally and it also leaves a “muddy like” debris in the sand filter itself.

Recently, I mix the clay together with the garlic in the food with no problems like before.

PS. Got one of the 20kg Shogun bags at the Year end function, so far the new Shogun mixes nicely with the garlic and the clay, and the Koi seems to like it as well.
