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.
The Koi for outdoor ponds are slightly bigger than what you would raise in your indoor aquarium. If you have a large fish tank, you could raise large fish indoor as well. An ideal backyard fishpond for raising Koi should be at least 3 feet deep.This is so your water wonât completely freeze over in the winter and so that the water temperature stays at bearable levels during summer.ou should make your pond large enough to hold at least 3000 to 2500 gallons of water so that you can keep 10 to 12 fish in there without overcrowding them. How big your pond should be depends on your budget, availability of space, and the number of fish you want to raise.
