Ponds - Construction, Filtration, Retrofits, Biosecurity, Keeping Koi

My ponds are finally coming out of winter, and the endless pursuit for better water quality this year has started!  I found this great article from Don Harrawood, Southwest Koi and Pond Association El Paso, TX.  It's great, detailed info on how to build one yourself, and I wanted to pass it along to all our readers.  There are lots of commercial versions available for sale (see one in use in the picture below) - but DIY is so much cheaper and more satisfying!

Someone asked me this question, and I researched the following answer.

Ultraviolet lamps are comprised of two electrode filaments (the spring looking wire at each end), a glass and quartz combination vacuum tube, several inert gases and approximately 3 mg of mercury (Hg).

One of my mentors in the Koi hobby was a guy called Roark, who used to have the most fabulous web site!  This article was originally posted on www.click2roark.com.  This is still considered the bible on Potassium Permanganate use.  PLEASE READ COMPLETELY BEFORE  EVER USING PP!

What’s MOST important to Koi during a power outage?  Quick answer – AIR!  Koi require oxygen to live, and without an air pump or a water fall running, they will quickly consume all available oxygen in the pond and die!

Water changes.  Most of us don’t do enough of them!  The list of benefits is nearly endless, and doing more water changes is probably the simplest, cheapest thing we can do to improve any existing pond.

Which of the following is NOT recommended for use as filter media - hair rollers, lava rock, Japanese matting, Kaldness media, Matala or bio balls?
