Checking your Lamp
Make sure your light is on and not burned out. If it is not lit up, you either have a burned out bulb, a bad ballast or an electrical problem. Chances are it is a burned out bulb, so order and install a new one.
Check your electrical source. If you have to, plug in another appliance to make sure it is working. If If the appliance does not work, you have an electrical problem. Check your circuit breaker box first. If you can see no problem there, call an electrician.
Decide how old the lamp is. Most ultraviolet lamps have a life span of nine to 12 months. If yours is older than that and is not glowing, chances are you need to change it.
Find out if your ballast is bad. It can go out because of flooding, lightning or power surges. If these things have happened at your house lately, you may need to replace the ballast.
Clean the sleeve. There is a sleeve that protects the lamp from the water. It can get dirty. That sleeve is usually made or quartz and is very expensive. Be very careful while cleaning it. Use the paper towels and vinegar to clean it.
Check the placement of pond equipment. Your pump should be as far away from the UV sterilizer as possible. Put your submersible pump at one end of the pond if the UV light is at the other. If the pump and the light are close together, all the water is not circulating through the light and getting sterilized.
