SGP Shadow: Natural Look Pond Dye

SGP Shadow natural look pond dye has proved very popular with gardeners that wish to treat their pond water with an eco-friendly algae control product, without a tint of colour.

Both the liquid and soluble powder sachets of natural look pond dye will disperse freely in your pond, controlling the amount of sunlight penetrating your pond water to inhibit the resources available to algae and submerged aquatic weeds.

Manual algae prevention can be time consuming which is not always practical for weekend gardeners. Our natural look pond dye is easy to apply, creating a natural looking ‘twilight effect’ that regulates your pond’s ecosystem to the benefit of pond life, fish and plants.

Natural look pond dye for larger ponds

In large ponds, volume of 200,000 litres and upwards it is not economical to use the DyoFix SGP Shadow 100.

In an effort to bridge the gap we are offering DyoFix Lake Shadow in a single 200g water soluble sachet.

SGP Shadow is eco-friendly

Free from herbicides, pesticides and algaecides, the natural look pond dye will prevent an excess of nitrogen which (if unchecked) can result in an algal bloom where algae reproduce in record numbers. Algal blooms are known to be harmful to other pond life, both other plants and fish. With SGP Shadow you are left with a wild-life friendly, natural looking pond for you and your family to enjoy.

Calculate the volume of water in your pond using the calculator below.

SGP Shadow Liquid

Half fill a watering can with pond water and add the measured amount, stir the contents. When mixed, apply to different parts of the pond.

SGP Shadow 15: 1ml is required for each 50 litres of water

SGP Shadow 50: 1ml is required for each 150 litres of water

SGP Shadow 100: 1ml is required for each 300 litres of water

Please note: The water will look to have more colour in the first few days because it takes a little longer to mix from the top to the bottom.

Top Ups

To maintain the level of DyoFix in the water, as a general guide, add 10% of the original dose monthly.

The first application should be made in early Spring.

Lake Shadow Powder 200g sachet

Each 200g water soluble powder dye will treat 800,000L of water.

But what can you do if you only need to treat 400,000L of water?

WE STRONGLY ADVISE NOT TO CUT OPEN THE SACHET
Hands and clothing are likely to become stained.

A simple way to divide the quantity of dye

1. Put 8L of water into a watering can
2. Place the 200g sachet and stir till fully dissolved
3. Pour carefully into 1L or 2L bottles
   • 1L treats 100,000L
   • 2L treats 200,000L
4. Fully secure tops
5. Use initial quantity
6. Store remainder for top-ups

Hints & Tips:
If the bottles have been standing for a long time, give them a shake before using.
It is useful to label the bottles so you will know what is inside and how much pond water each will treat

Reference Samples

If reference samples are desired, it is suggested that these should be taken at least a week after the initial application. Samples should be in clear containers with a secure lid, labelled with the date and location and stored in a dark place. An initial comparison to tap water will show the amount of colour present in the water.
