I would highly suggest looking into a bead filter with a UV sterilzer. Not
because we sell them, but we sell them for a reason... (after 10years building
and servicing ponds).http://www.macarthurwatergardens.com/Stan_Goff_Pond.htm
(A pond we
built with very similar dimensions to
yours)http://www.macarthurwatergardens.com...challenger.htm

Brett.....I know you are new here, but
there is a rule about spamming.....Like DON"T DO IT.....everyone of the posts
I have read from you is trying to sell a uv or someother thing. If you want
to post or answer questions fine....but we do not need your spam here.
Jerri.....( who has had ponds longer than you and doesn't sell anything)
