[3dem] Cooling water

[Tim Gruene]

Dear Ruben,

we use singly distilled water, buffered to pH 7.5-pH8 with baking
powder or Na-phosphate buffer. It should not be sour to prevent
corrosion. We also add Thermoclean Blue to keep  algae and bacteria
out, and refresh the Thermoclean annually.

Best,
Tim
