Splashtastic Aquatics goes back to Chicago to help M out with the Koi Whisperer Sanctuary. Here is the article MaryEllen wrote up on the work I did for her and the sanctuary.
In June 2010, my indoor koi pond was updated and a waterfall feature was added.
For a number of months the system worked well however water conditions and clarity were always a problem and alot of work and effort had to be done daily to maintain the pond for the health and welfare of the koi imported here. I never had water problems before, and even with a high stocking level of imported koi, routine water changes was sufficeint with the external pump filtration I had installed. In March of this year, 2011, many of our KWS Koi Keepers read the devastating news that the pond had collapsed and I woke up to a koi pond full of boulders, stone, muck, and waste.... and my imported Nishikigoi struggling at the bottom in only a few inches of water! The pond was rebuilt with my own specifications which was adhered to by the pond builders. If you missed the article it is available to read by clicking here.
