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.
Report Abuse. You need a pretty large tank for koi, at least 100+ gallons. It would be best for larger, like 500 gallons. Most people who keep koi keep them in a pond, where they say 1,000 gallons for one, and 100 gallons for every added. Instead of koi i would get either goldfish (they can get pretty big and be beautiful) or tropical fish. Goldfish need at least 30 gallons for 1, and 10 gallons for every extra one. Tropical fish can be small and only need 5 gallons(such as tetra's) or large and needing 30+ gallons.
