I put finer thread bolts on, got the air out from behind the disc and hooray found some fringes, the water is shallow, readjusts in about 5 sec. How is the light setup? I can only see fringes in the reflection of the tube light and when I level it more to get less lines they fade. They're visible but didn't photograph.
