Aquascape Blue Pond Dye - 8 oz / 236 ml

Both cut light equally well - the difference is the look. Blue gives the classic bright lagoon appearance and suits ornamental and amenity ponds. Black gives a natural reflective surface that mirrors the sky and trees, and tends to suit naturalised or wooded settings.

Neither affects performance, so choose on the look you want.

Spring, before algae gets going. Dye is preventive - applying it to a pond already carrying a heavy bloom will not clear what is there.

Top up through the season as it dilutes with rainfall and outflow.

Pond dyes are formulated to be safe for fish, pets, livestock and wildlife at label rates. Follow the label for your water volume.

Dye will temporarily stain hands, clothing and porous surfaces during application - wear gloves and pour carefully at the shoreline.

Dosing is by water volume. Estimate yours by multiplying average length by width by depth in feet, then by 7.48 for US gallons, and check that against the label rate.

Send us your dimensions if you would rather we worked it out.

Liquid dyes can be damaged by freezing in transit, so there are periods over a Canadian winter when we will hold an order rather than ship it.

We will tell you before dispatch rather than let it arrive frozen.
