I have lost an average of 0.6" daily. The water level is now almost below the openings of the skimmers, and I'm curious to see if it stops there. The day that I did the dye test, I ran out of dye before I made my way around to the second skimmer (have two). I have now bought more dye and am planning to use it inside the light niche, but I'm tempted to wait a little bit and see if the water continues to drop below skimmer level.
