Pond algae and aquatic weeds are a common problem for many people. A common question that’s often asked is, can pond dye help?

In most cases, the answer is yes. To stop algae and weeds from taking over, pond dye can help get the water cleared up once again. There are many dye products available to address such situations. They work in a natural way, which will not harm fish, frogs and other aquatic life that may exist under the water’s surface. Such products are safe for humans, pets and other animals. If used correctly they will not discolor skin or hair.

Blue pond dye does not work by directly killing the unwanted algae and growth. It works by blocking light that is essential for the growth of plant life. Though much of this growth may sit on the bottom or bed of the lake, the sun’s rays are still able to get through to continue the process of photosynthesis. Aquashade, which is one type of dye, works by diffusing the sun’s rays from getting past the surface of the water, and limits light exposure to the algae and other unwanted plant life that grows from the lower regions of the water.

Using a natural product has many obvious benefits. There is no need to worry about pets or children being harmed by playing in the water. Fish and other live creatures do not need to be removed prior to treatment. Chemicals, such as algaecides or herbicides, can leach into the ground surrounding the water source. If gardens or other planting areas are located nearby, they could be affected. Pond dye does not add harsh chemicals and is non-toxic. It is good for the water source, the surrounding area and for those who play in or near the water.

If you decide to use a product such as pond dye, do not be alarmed when it comes out of the packets or container looking black. It will get lighter as it disperses throughout the water. It is important to use enough product to treat the entire lake effectively. The natural movement of the water should disperse the entire contents throughout the entire surface within a day or two.

A typical pond dye product will cover a one acre water source up to five feet deep. Therefore, it the water is deeper, an additional gallon may be required. During this time, it is advisable to keep out of the water, until the crystal blue color has spread throughout the entire area.

It’s advised to wear rubber gloves, so the tinting will not get on hands and stain them. This is particularly related to the liquid dye, as the powdered dyes that come in water soluble bags is a bit less messy. Pond dye products for large ponds range in price from $30 to $79 and can be purchased in quarts or gallons. In terms of some concentrated dye, a single quart can treat up to one acre in size. There is no limit to the number of times pond dye can be used in a year.

For the best results, it’s suggested to use the first application at the beginning of the growing season, to catch algae or weeds before they get out of hand. Early management and control is often easier rather than waiting until the problem growth get’s well underway.
