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.
Step 1. Obtain an aquarium that is large enough to contain the number of koi you have. Koi need a large volume tank to thrive. Your tank should have 1 cubic foot per 1 inch of koi fish length. Multiple the tank's height by width by length to determine the tank's cubic footage. Put the aquarium on a stand that can support the weight of the tank, and find a location in your home that can accommodate the weight of the tank safely, such as near a support wall or on a concrete basement floor.
