I have to ask what would you use for cooling fluid in a loop I am pulling my loop down and am probably going to put the antifreeze back in I like the idea of pure water because of thermal efficiency but corrosion and algae are the main issue I would rather avoid at all cost.
I just looked at you profile of course it would be Mayhems Pastel or any other computer grade coolant.
Yes you would be correct in assuming that i use Mayhem's coolants(although my profile is very old, and i will be updating it soon-i am light years ahead of that rig, not to mention, knowledge-wise now)
At present, i am using a white pastel, to which i added coloured dye-very nice effect and no problems whatsoever with regards to plasticizer (as yet) nor algae growth.
Mayhem's also make X1 which is a clear coolant, which also has anti corrosive and anti bacterial properties in it, so you would just use it on it's own in a loop.
If you dont want to pay that much, you could go with Distilled water -try to make sure that the Ph (acid/alkaline level) is at 7-that is neutral).
Then you could buy a dye such as mayhems dye and add it to your loop.
With regards to the SKC and biocide issue-i only know of one tubing at the moment (not including certain Tygon food/beverage type tubing) that claims
to not need those items, and that is Primochill Advanced, BUT
do not take my word as gospel, because i have not used it enough, nor in that configuration to make a valid personal
comment as yet.
There are other users in this thread that have said good things about it, but, the tubing is new(on the market), and i do not know what they have used in their loop (the consumer)- so i could not say with certainty 'x' user has had 'x' results etc.
A good rule of thumb when deciding what to do, is to take advice from people that do not back up their claims (both negative & positive) with properly documented proof, with a pinch of salt, there are many over enthusiastic people out there, many fanboys, and others with hidden agendas.
Decide on which tubing you want to go with by reading up a bit to get a rough idea what you think will work best for you, then go ahead and build your loop-you will soon see if your choice was correct.
Hope this helped, if only a bit, good luck in your battle to stave of algae Edited by kkorky - 2/7/13 at 10:24pm
