Thanks for the info,

Is Oase a good bet ?? I had a look at a brochure myself and the look
well made. I presume with you only just acquiring the system you have not
had to much time to asses it's performance.

One other quandary I have been mulling over, I had my Butyl liner
delivered today and wondered if it is better to install it now and leave the
pond over winter, though there will be no stock and I wouldn't be circulate
the water, or leave it bear till spring, any thoughts ?

Cheers

Jason

According to my Oase brochure, a Koi pond of 8000 litres is suited by a
BIOsys3, consisting of a Biotec 10 filter, a Bitron 15 UV unit, and an
Aquamax 10000 pump. I've just bought one, total cost £499.
They told me in the shop that pressurised systems are a load of carp.

Hi everyone.

I'm a newbie to pond life (excuse the pun) and have a few questions
to
ask, if you don't mind. ....................

A little back ground to myself and the pond I'm in the process of
constructing. I've been a water keeper for 15 years, firstly tropical
then
onto a marine reef system, which I've had for 3 years and is my little
baby!
So I'm no newbie to keeping fish as such.

I've recently started to construct a 9'x9'x4' ( approx 7000L /
2000G)
pond in my back garden, the hole is dug and the frame work is all but
complete. This I've made from 9"x4" Tanalised rough sawn planks, not
seen
many "wood" ponds so I thought it would be novel, though a bugger to
construct !!!! Although I don't intend to stock this year (I'm up in
Derbyshire UK and it is getting a little cold) but my aim is to stock
with
a
mixture of Kio, Orf's and a Sterlet or 2.

I've been doing some research on filter UVC and pump systems and
also
asked around a few fish keeping friends for advice on equipment
selection,
but would value other input. The main to concerns are the filter and
UVC,
I've narrowed it down to either the OASE Biosys Promax 30000 or the
pressurised Fishmate 6000UV. Budget is an issue so the Evolution Nexus
range, which I like the look of is out of the question. Has any one any
experience with these products or recommend any other ??

Another quandary is whether to fit a separate UVC or will the in
built
UV's be good enough? Also I have read in some places that you fit the
UVC
after the filter box and some before, the arguments being fitting after
doesn't kill of any of the Nitrifying bacteria, but before helps the
mechanical filter media to remove more of the "clumped" algae cells, any
thoughts?

I'm also debating whether to go for a solid or pre-filtered
submersible
pump (something like the Fishmate 2500), which is advisable? Lastly on
though thoughts of aeration, I will have a slate shelve for the water to
return to help create surface movement, either fed directly from a
pressurised filter or as a bypass on a gravity fed, my pond construction
is
above ground level by a few feet, so the gravity fed would have to be
top
exit. Also does anyone else use a separate air pump for aeration or
does
most people just rely on surface agitation?

Any links to sites would be appreciated, my crawl of the web has thrown
up
many conflicting views, suppliers always say THEIR product is the best,
but
I'd rather ask the people who REALLY
know.................................... you!!!!


Thanks for your thoughts in advance



Jason.
