True Blue water dye is a simple and very effective way to reduce aquatic weeds. It is great for small ponds under 50′ x100′, but more product can be added for larger ponds. True Blue water dye is used to give a deep blue color to your pond. True Blue Water Dye can also help filter out the sunlight to the aquatic weed vegetation that is not wanted in your pond. This is an inexpensive way to control the weeds and algae in the deeper parts of the pond.
True Blue Jet Black is also available and some customers with larger ponds mix it 3-1 for a different shade.
True Blue water dye in a 4L jug can be used to pour in spots around the edge. The color can be topped up if needed. With less aquatic weed vegetation growing you are giving the bacteria in the pond a chance to catch up in the removal of phosphates and sludge resulting in cleaner pond water. this is because the oxygen level goes up as it is not needed for sludge decomposition. With less organic matter growing in your pond the lessor the nutrients and the cleaner the water quality.
