So, imagine my surprise when I arrived at boat club last week to see this:
Bright, green water!
Seriously - bright green!
It turns out that as part of out weed reduction programme, the water has been treated and one of the chemicals is a green dye. None of this harms the fish, but should kill off the floating weed the lazy blighters haven't been eating.
If you prefer clear water, the a friend recommends a trip to Akri in Greece.
