A customer has a 1/4 ac pond that they just have for fish. They use so much dye in it that if any water splashes up, it's blue too. Think of a dark Tidy Bowl blue.
Slightly off topic:
esshup,
Do you know HOW they fish that pond? I was just wondering if only certain angling techniques work when the fish are always in water with very low visibility.
(Or is it a brooder pond for a main pond?)
