Back in the early days of pond keeping some clever sole not sure who that was made a fantastic discovery that changed ornamental ponds for ever.

Ultraviolet Light is damaging to single celled “green algae” – a common cause of murky water in ponds.

Zap the algae with powerful UV rays and irreparable damage is inflicted onto the DNA. Yes exactly the same process that can cause skin cancer and makes you look like a prune by the time your 50.

Once the DNA of the algae is damaged it tends to form heavy clumps that, sink to the bottom of the pond or get trapped in the filter media and then die. So long as you’re killing off the algae faster than it is multiplying the water becomes crystal clear and you can see your lovely fish.

UV are rated in watts. Watts are a measure electrical power consumption As a general rule of thumb I would suggest that you allow at least 10 watts of power for every 1,000 gallons or 5,000 litres of water in your pond.
