Today, TVo and I found and fixed a leak on the TCSX table on the first T connector in the supply line.

He mentioned to me this morning that he had to add a few liters of water yesterday, so we went leak hunting this morning and found corrosion on the base of the periscope, water spots on the table in the corner, and spots on the floor below the table. No optics had any spots since the leak was coming from a T connector on the supply line behind the periscope. We cut about an inch off of what seemed to be the leaky connector, and then reconnected it and turned the chiller on. No leaks so far, but we will keep an eye on it the next few days to make sure we actually got it.

While we looking for the leak we found that the T connector for the return line had a hose that was about to come off (or possibly wasn't seated well to begin with). We fixed this while we were in there so I can sleep at night.
