Hi,

Anyone using these or can share their knowlegde on their usefulness? I
thinking about getting a largish setup (2000 L) and was wondering if one of
these could help keep the water changes to a manageable level?

I was looking at the http://www.aquaripure.com/ website - anyone with any
experience of this product?

Hmmm... I would suspect that this is simply a de-nitrate coil... which
you can create yourself for just a few dollars. All you really need
is a long, as in 15-20 feet of small diameter tubing, airline size
works, but it has to be completely blocked from all forms of light.
Any, just a slow, almost drip type flow through this tubing will help
eliminate nitrates. This can not be run by a very strong power head
without some form of flow control to limit the speed of the water
through the system. The slower the better.

From the pictures on that site, they are only using about a 1/4 inch
tubing, and there may or may not be a power head contained in the
box... of course they are not going to be willing to tell you that
this is very simple technology. The only downside to these types of
de-nitrate systems is that since they are a small diameter tube
system, the flow rate is sooo slow that the nitrates in your tank may
still continue to rise if there is not enough turn-over.

Shoot, it looks to me like it is a BIG rip off... there is nothing to
it but a coil of tubing hidden in a 'black box' to block light.
