Cleaned up the wiring a bit:
Question 1:
I spoke with a fish store owner today asking if I need a biocide in my loop. After explaining my rig [owner new nothing of liquid cooled computers, and found it fascinating] he asked if it is in direct light. I replied the only light that hits it is from the ceiling fan. No direct natural light. He told me I don't need anything in my loop to prevent bacteria, etc., and distilled water should be fine on it's own. Now, coming from some one with a store full of running aquariums I want to believe him. However EVERYTHING I read on line regarding a loop(s) state the opposite. So, do I NEED to add something to my loop or not?
Well, almost all algae that are commonly encountered use photosynthesis. In
order for them to survive they need
- nutrients (mostly nitrogen and some other stuff)
- sunlight (or artificial light of similar quality)
- not too many poisons in their environment
If they don't have that in your loop, they simply cannot, by the very fucking
laws of biology, survive. So even if they have light, how the hell will the nutrients
get into your loop if all you're using is distilled water? I think most gunk people
encounter in their loops that they think are algae is actually just dirt, from
whichever source. I have
never in 12 years of reading on W/C seen any
actual algae (you know, the green stuff) in anybody's loop. You
might
get some bacterial growth, but even that would be tricky without having
nutrients in the loop. Even bacteria need something to feed on (possibly
the PVC tubing? Not sure about that).
And back in the early 2000's there was a lot more ghetto modding going on
and even then I never saw something like that. I would say it's possible if
you're running
normal water.
Water cooling people are not exactly experts on the biology of water habitats
(neither am I, I'm just going on my high school bio and wikipedia here :lol: ),
and I think somehow a lot of misinformation has just spread and, unfortunately,
stuck over the years in the community.
A guy who runs an aquarium shop should (I would hope) be a lot more
knowledgeable about what sort of stuff can grow in water under what
conditions. Keeping fish and plants alive in a water tank is a lot trickier
than cooling a few bits of silicon with metal bits that are flooded by
water imho.
I think asking that guy about this was actually a great idea!
Besides: What's the worst that could happen? You get some algae in
your loop, big fucking whoop-de-doo. Empty loop, run some cleaning
fluid through it, fill it up and you're golden again.
What
is a concern though is corrosion, but that's a whole other topic
and I'm really too tired to write a dissertation on that now (I actually
had to take a semester of chemistry in college that dealt with that
specific issue among others because you don't want to be building
machines that fall apart from corrosion in mechanical engineering

).
Maybe later :lol:
Question 2:
I'm not sure if my math is right. [I suck at math. I'm one of those "measure fifteen times - 2nd guess - meausure 3 more times - then cut" types] If running a CPU block, 2 GPU blocks, 3 480mm radiators, and a Bitspower 150 res my calculations show it is super expensive to run say Mayhems pastel white for example.
I am ball parkin' a gallon of fluid needed because I am currently using a half gallon of fluid with out 2 480mm rads, GPU, and CPU block installed
Mayhems Pastel White Concentrate $21.95
250mL makes 750mL of fluid
1 gallon = 3785.41mL
3785.41mL / 750mL = 5.04721333333333
5.04721333333333 * $21.95 = (rounded up) $111.00
Am I right and it's that expensive to run Mayhems in my completed rig IF only 1 gallon of fluid is required? It seems too expensive which is why I am uber-second guessing my math.
It is very late here (well, 4:50 am

), so the reliability of my internal
calculator is dubious at best. But that does not sound extremely unrealistic.
Good night, and good luck.
