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.
1. Select a proper pond. You can purchase a Koi pond made of several different materials from pet stores or Koi specialty retailers. A good rule of thumb is that the Koi pond measurements should be at least 3 feet (0.914 m) deep and contain 300 gallons (1136 liters) per fish.eep the water fresh. While some Koi ponds are large enough to be naturally aerated, pumps and filters can ensure that the water in which your Koi live stays fresh. You may want to consider using Koi pond water additives. Two examples of additives are products designed to keep the water healthy and free of pests.
