I have a fiber optic light in my inground vinyl pool. The light it gives has been inferior since installation, but lately it seems worse. The lens in the pool appears to have algea inside it. Does anyone know if I can remove the lens & clean it without having to worry about water enetering the area when I remove the lens. Also, does anyone know if the inferior lighting is normal, obviously the dealer recommended this lighting (they are now out of business) or perhaps I could do something else to enhance the lighting effect. The pool is 18x38 grecian. Thanks, Any help is appreciated :?
