Filter Media Can't Post

Hey,

I am planning to build a 6 x 2 x 1.75mtr Pond. For the media I was thinking of just having vortex and bio-ball.
I know it might sound very simple, on a tight budget, so Blush. Was wondering if this setup is ok?
Oh, the filter media will be around 30 - 35% of the pond volume, also there will be a Bakki shower added too.

Thx

A very similar setup was used on the pond of 'Carloskoi' (see his post on www.koivet.com and www.koiphen.com). His pond used a vortex/settlement chamber and a large trickle tower system.

Now, with these bioballs, they are more effective when used in a trickle tower (TT) format (where the water cascades from the top down just like a bakki shower). Providing sufficient flow and water coverage, the TT should be more efficient than a similarly submerged grouping of bioballs.

You would therefore have a bottom drain going to the vortex, into a second chamber with a prefilter mat (just so you could get the really dirty debris out of the water) and then have a water pump in the last chamber. Here, chambers 2 and 3 would be relatively small. The pump in chamber 3 would pump the water into the TT at the top, where the water would exit out the bottom and back into the pond.

Hi,

Thankx for the reply, I guess chamber 2 should be bigger than chamber 3, as I can fit in bio ball at the bottom and prefilter mat on the top. Is it necessary to have the vortex chamber lower than the pond(I know that the gravity helps, however I don't think I have the space for the vortex to be placed lower than the pond), I am thinkin about having it on higher ground (with the aid of an extra pump to suck teh debris and push it into the vortex). Is it doable?
