Control algae and weeds with SGP Blue pond dye
Eco-friendly SGP Blue pond dye maintains a stable environment in your garden pond by preventing sunlight from creating the abundance of resources that lead to unsightly algae and weeds.

Garden pond owners can experience what’s called an algal bloom when resources are plentiful leading algae reproduce in record numbers. Consuming larger and larger amounts of the resources available, the bloom can kill other pond life, both other plants and fish.

SGP Blue is harmless to fish
Manual algae prevention can be hard work and is not always practical.

The use of chemicals, algaecides, herbicides etc (if not used in precise doses or under strict supervision by experts) can cause an imbalance of the natural nutrients in the pond. This may have a negative effect on fish, plants and other species.

Dyofix SGP Blue is an extremely economical solution for preventing algae and aquatic weeds in garden ponds.

Key Features:

• Works in all garden ponds, small or large
• Very economical to use
• Simple application methods
• Saves time and effort
• Blocks light, denying algae’s food source.
• Lasts up to three months
• Free of pesticides and herbicides
• Harmless to plants, fish, filters and wildlife
• All year round use

Application Methods:

Calculate the volume of water in the pond (see calculator below).

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 Blue 15: 1ml is required for each 50 litres of water
• SGP Blue 50: 1ml is required for each 150 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.

Topping Up

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.

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.
