Water: the most complex necessity for life.
Its temperature can change as can its acidity and salinity. Things are dissolved into it. Things are added to it and taken from it. It can be a solid, a liquid or a gas. It can originate from the sky or from the ground. It can be hard to contain, as it will move anywhere it has an opportunity.
Nature provides us with “living water.” As water flows from snow or rain to the ocean, it becomes impacted by the sun and air. Living organisms such as algae, bacteria, plants etc. begin to make up the biomass of this water.
Along the way, minerals, micro-nutrients, pollen and organic matter are picked up. The parameters of acidity, salinity, temperature, hardness, oxygen levels, etc. balance out and are all dependably stable.
A Koi pond must try to mimic nature. It is a closed system, and dead leaves, pollen, fish waste, and other contaminates must be eliminated.
Effective filtration, and water changes make it possible to allow us to grow beautiful and healthy Koi. Raw (tap, or well) water is added in increments, which helps age it and integrate it into the existing pond water.
Filtered waste water is used to maintain our gardens with nitrate-rich fertilizer, and it is used as the basis for aquaponics.
We now plan to go a step further and also treat it to go back into the pond so absolutely no water is wasted. With hundreds of ponds in Colorado Springs alone, water saved from these necessary changes makes a huge difference in Water conservation.
