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.
Typically, Koi should be in ponds that are at least 1,000 gallons. Avoid Overstocking the Pond To maintain healthy fish and clear water, do not overload the ecosystem with too many fish. For a new pond, a good rule of thumb is one inch of fish per square foot of surface area.ecause Koi grow larger, place one Koi for every 10 square feet of surface area.
