I installed a new 10,000 gallon pond with stream system that acts as my bio-filter.
The water is excellent quality as a result - and the koi/goldfish are thriving (fat, big and happy).
But - the water is quite green (even though in winter). I thought the stream (with lots of water plants along the bank) would suck out the nutrients from the water and prevent the single celled algae from growing to dense - but not to be.
I am thinking of installing a UV light system to kill the algae and get clear water.
Can anyone suggest a UV light sufficient for this size pond? I'll post pics when I get a chance.
