Pro Blue+ Lake Dye, manufactured and supplied by The Blue Lake Dye Co-operative in the UK, is a concentrated liquid water dye designed to enhance and manage ponds, lakes and other inland water bodies across commercial and recreational settings.

From its base in Northamptonshire, the company produces and distributes Pro Blue+ lake dye in 5L and 25L tubs, offering nationwide delivery with larger orders transported by road and smaller quantities shipped via Parcel Force within 48 hours.

The product uses vegetable-based food dyes that have a longstanding history of safe use for waterbody treatment.

Pro Blue+ is highly concentrated — with 1L treating more than five million litres of water — and is formulated to create a stable blue tint that can last throughout the summer when used at the correct concentration.

The dye helps reduce sunlight penetration, which can limit algae and weed growth while improving the visual appeal of the water.

It is environmentally friendly and non-hazardous, with safety data sheets available on request.

The company serves a broad range of clients, including watersports venues, fisheries, golf course ponds, park lakes and private estates, positioning Pro Blue+ as a robust solution for both aesthetic enhancement and ecological water quality management.
