An inductively coupled plasma (ICP) for spectrometry is sustained in a torch that consists of three concentric tubes, usually made of quartz, although the inner tube (injector) can be sapphire if hydrofluoric acid is being used.n inductively coupled plasma (ICP) for spectrometry is sustained in a torch that consists of three concentric tubes, usually made of quartz, although the inner tube (injector) can be sapphire if hydrofluoric acid is being used.
We recommend the following GPK (gallons per Koi) rates based on their size: Small Koi (2 - 8): 100 - 150 gallons. Medium Koi(8 - 14): 250 - 300 gallons. Large Koi(14 - 24): 400 - 500 gallons. Jumbo Koi(24 - 36): 750 - 900 gallons. The GPK estimates are based on long term housing for the Koi. Indoor winter tanks can be small, but must accommodate enough room for the Koi to swim around comfortably.
Large size Koi can easily be worth $1,000 each, great quality Koi can bring $250,000 each or more, but are rare. However, to do this you would need to have a unique resource such as a 50,000 - 200,000 gallon pond. Once you have the pond you would have an inexpensive way to raise large numbers of Koi, while enjoying them. After 3 or 4 years the Koi should start breeding themselves. One female can lay 100,000's of eggs. Of course there could, and probably would, be unknown complications to such a rosy story.
