Added 205ml cooling water to the TCSX chiller. First water added to TCSX in the past month.

Added 600ml cooling water to the TCSY chiller. Given the amount of water loss with the TCSY Chiller but not with the TCSX Chiller over the past three weeks, I am suspicious there is a leak in the TCSY cooling loop.    

I added marks (at 1/4 , 1/2, and 3/4) next to the site glass so we can more easily track water loss.
