Coloured water in your pool

Oxidised metals in the water can lead to coloured, translucent water and can even stain the pool or spa wall surfaces if not treated properly. Green, red, brown and black are some of the more common colours found in pool water when dissolved metals are present.
The sources of minerals can be:
– Fill water,
– Inadvertent additions of chemicals used in lawn maintenance,
– Specialty treatment chemicals such as algaecides and,
– Poor water chemistry resulting in the corrosion of metallic components of the pool system.
Some source water contains iron and/ or manganese that can give a distinctive brown or red colour. Try to minimise the chance that products designed for another application like landscaping can get into the pool. Corrosive water conditions could dissolve pool walls, handrails, ladders, light fixtures, heater components and pump impellers or casings.
Older pools and spas may be plumbed with iron or copper pipes, rather than with the PVC plumbing used in contemporary pools. Corrosive water, usually caused by low pH, can dissolve the copper from the exchanger elements. This can cause the water to take on a green or blue-green tint, with a potential to stain the pool or spa wall.
Stainless steel fixtures such as ladders, handrails and light fixtures contain iron. Corrosive water can also dissolve these items. When the water has a tint it is important to determine the colour before beginning the treatment programme.
