I have a two year old gunite pool with a Riversand (Riverbend-Sandler's version of PebbleSand) finish. One of my lights has a little water in it, but it appears not to be filling up any more. A friend of mine speculates that there is a small leak towards the bottom of the ring and that the pressure has now equalized, preventing any more water from leaking in. The water level doesn't seem to change over time. Should I leave it or replace the gasket?
Also, the rings are chrome/brass and the chrome is almost all gone already. Is this normal? Could it have been due to a bad startup, i.e. chlorine but no CYA? Should I worry about it?
Forgive the blurry picture, but I just stuck a camera in a ziploc bag and went for a swim.
