There are different options you can try if you would like to dye the water in your water feature, but some are better than others.
Food coloring can ruin your water feature if you use too much or the wrong kind. It can dye the concrete, ruin the pump, and erode the surface of the fountain. Certain food coloring could also be harmful for birds and wildlife. However, pond dye is a safe alternative.
What should I do if I still want to dye my water but I don’t want to ruin my water feature? Which water dyes are best to try?
Food Coloring Versus Pond Dyes
Oil based food coloring should not be used in water features. It has certain acidic chemicals that will erode the surface of your water feature over time. Some food coloring are highly oily and acidic, which can ruin your water pump. The acid will break down your pump just like the surface of the water feature. The oil in the food coloring will also gum up your pump over time.
Food coloring is likely to stain anything it touches, including cement, plants, even animals. If you do not want your water feature itself to be stained, then you should avoid using food coloring. The oily properties of some food coloring can also be harmful to fish.
If you are determined to use food coloring in your water feature, make sure to only use small amounts and to stay away from oil-based food coloring.
If you still want to dye the water in your water feature, but you want a safer option, you should consider trying pond dye. Pond dye can be used for small or large water features, such as a small fountain or a lake. It is safe and beneficial for both wildlife and plant life.
The dye helps to block excessive sunlight and helps to slow the growth of algae and other unwanted aquatic plants. If this is your main reason for dying your water, then you should consider using a black dye. The dark color blocks the most UV rays and will help kill algae.
Pond dye can also be beneficial for wildlife by helping to lower the temperature of the water in the summer. The dye not only blocks out sunlight but it also blocks the vision of predators from above, protecting your fish from birds or animals along the banks of your pond or lake.
Unlike food coloring, pond dye will not dye or erode the surface of your water feature. It is still a dye, so you might want to consider using gloves during application, but once the dye has been diluted by the water, it will not dye surfaces or skin and is safe to touch.

Different Colored Dyes
Dyes can typically be purchased in three different colors: blue, turquoise/aqua, or black. You might want to try all three and see which one you like best, but all three colors are good for different reasons.
Blue dye is great if you have a lot of green foliage next to your water feature. The contrast of the blue and the green really makes the colors stand out. Blue dye is great if you want naturally beautiful looking water. It does a good job at blocking out the sun rays to slow the growth of algae in your water feature.
Turquoise/aqua dye is another good option if you are looking for a more tropical feel. The water will be a lighter color and more clear than blue or black dyes. However, because the dye is lighter, it will allow more sunlight into the water and will not help as much with algae control.
Black dye is recommended for larger bodies of water, especially during the winter. In the winter, the dark water creates a mirror effect, which goes great with a white winter. In the summer, the dye will still have a strong reflection, which can be beautiful if your pond or lake is surrounded by a lot of foliage. Black dye also blocks the most sunlight, which helps your fish hide from predators and stops algae growth.
