Added 150ml water to the Crystal chiller. Diode chiller was OK. Noted no new contamination or debris in either chiller filter. 

   Trended the pressures and flows for the Diode and Crystal chillers. The pressures are still slowly trending upward and the flows are trending downward. Both are changing by very small amounts. I have the new (higher flow and less restrictive)filters for the chiller room in-line filters. Plan to swap these at the next maintenance window.
