red water in trough

My son in law has a rainwater fed galvanised trough which has developed a red oily film on the surface of the water. There is no rust around. The only tree near is a cypress. Any ideas?

It's likely to be an algal bloom, similar to green water in ponds, tanks etc. They come in different colours. I wouldn't drink or bathe in it, but it's fine for watering the garden.
Gardening in Central Norfolk on improved gritty moraine over chalk ... free-draining.
Its the fact that its oily that worries us. He uses it to soak his chestnut for his trugs and it is leaving a red stain. He has never had this prob before in many years of trug making
Thanks that sounds about right
