Here's a question:
"Why do modern loops algae up?"
I ask because I ran a loop back in the days of the Astek Waterchill kits and AXP 2500+, and for 2 years I didn't have a single bit of build up. Is it down to the additional heat, or is it just in extended/hard usage cases like Biffa's where this is a problem?
They don't with the appropriate additives.
Biffa, this is plasteciser from the crappy primochill tubing isn't it? Stained green by the dye in the coolant obviously..
