So I bought a Yamitsu 30watt UV sterilizer in the summer of 1997, which cost me £79, although slightly underpowered, (as it is recommended to have 10watts per 1000 gallons) it was the most I wanted (or could afford) to shell out, as I was doubtful if it would clear the troublesome green water.
Installation was started the next morning, this entailed the cutting of one of the pipes from the pump, and fitting the uv unit in-line ... ...had to supply my own jubilee clips to complete this.
The unit must be sheltered from the worst of the elements, mine is covered by some old pond liner.
It has to be plugged into the mains, but it is supplied with a 10mtr cable, so it has a reasonable range to it, I would also recommend that you use a power breaker when plugging this or any other outside appliance into the mains electricity supply.
I had a lovely pond of 3500 gallons, but the water in it was the colour of pea soup (mucky green), not very nice and not compatible with viewing my collection of fish.

Installation was started the next morning, this entailed the cutting of one of the pipes from the pump, and fitting the uv unit in-line on this cut pipe, using the supplied stepped hosetails, I had to supply my own jubilee clips to complete this. The unit must be sheltered from the worst of the elements, mine is covered by some old pond liner.

The pump was turned on, and with no leaks apparent, it was now time to turn the uv unit on. A WORD OF WARNING: Never look at the uv bulb as it can damage your eyes.
A faint glow was seen through the hosetails so I knew the unit was on. Now to wait and see if it worked. The change within 2 weeks was almost unbelievable, I could now see the bottom of my pond,(which is 5 feet at it’s deepest),and my fish.
The maintenance carried out on this product has been: Each spring I change the uv bulb,(although it is recommended to change bulb every six months), and at the same time clean the quartz tube. When replacing the bulb, do not handle it or the quartz tube with bare hands, and disconnect from the mains first. Replacement bulbs can be purchased for approx £10.
The uv on my pond is switched on all day everyday, and has been for nearly 4 years, other than when I’ve done the above mentioned bulb changes, and for a six week period when the fish were under going treatment for a parasitic infestation. UV rays can nullify the effects of any medication you use in a pond, so please turn them off if you are medicating your pond or fish.
The reason a uv works: The uv rays kill the algae cells as they pass through the UV unit,so stopping them multiplying and turning the water green. Simple.
