Re: Best Floating Beads

[Lee B.]

The "Latest and Greatest" in the bead type media is something called
Kaldnes. To get the maximum out of it, you need to install hefty airstones,
manifolds, or the type of air hose used in sewage treatment plants to "roil"
the media with air. It becomes self-stripping, self-renewing, and adds a lot
of oxygen to the water. It's designed to be used in open containers, not
pressurized filters.

The beads used by the bead filter manufacturers is a low density (around .95
specific gravity) polyethylene bead. Find someone making milk bottles, of
something similar and see if you can buy the beads that they use in their
manufacturing process. When I got my bubblebead filter it came with a bag
of beads from Dupont or Dow. I forget.

Sells Kaldness media #423160 $1.50/liter usually in 50 liter bags
A sample of the bio media can be seen at
http://ourkoipond.com/Temppond.htm it's the small white ones. They use
them in their tank system. It is also used in the nexus filtersystems

Roughening the beads might be good, but the beads that came with my bead
filters were not roughened and they work fine in both bead filters. The
poly beads are for a pressurized system, with the water flowing up through
the beads and into a slotted pipe for discharge back to the pond. The
kaldness is a floating filter media that is more like hollow tubes that are
tossed around in an open filter by high air flow. The discharge from a
kaldness filter is not from the top. The kaldness is the best material for
converting ammonia to nitrites, and nitrites to nitrates, but beads will
perform that function and act as a mechanical filter for fines. One of the
ponds I visited recently uses the kaldness for the biological filtration and
then sends it through a bead filter to polish the water by removing the fine
suspended material.
