We thought you might enjoy a picture of all the salt we need just for one greenhouse! This greenhouse holds approximately 53,000 gallons of water, and to bring the water to 0.3% salinity we add 33 bags of 50lb salt. We normally keep our greenhouse water without salt except for when we are bringing in koi from the mudponds. Since koi experience gill congestion when moving from muddy water to clear water, salt helps to ease this, as well as stress. Imagine how many bags of salt we go through at harvest time…
