Time to go Water Cooled (need some professional opinions and help!)

[Bevel]

Yeah it must be worth at least trying.
Good to see another kiwi in here, Im in Hamilton - hot as hell up here lately, sleep is hard to get. I had a neighbour from dunners move back down south as it was to hot for him!

if you really want to try,
suggest distilled water + chlorine in different concentrations in several glass jars with an oring and a pice of tubing for testing purposes.

I dont think that would achive much as o rings and tygon tubing are both chemical resistant. I think you would have to add a piece of copper and some anti corrision fluid to the mix to get worthwhile results. As long as the chlorine level is kept low like drinking water I do not see a problem.
Have I just put an end to the anti algae debate?

and that level is ?
you need to test the water -> maybe a kit (like a pH kit)?
else you need to make some sort of testing procedure (as i stated),
probably in a heated enviornment similar to a WC loop,
although i think it would take some time to actually get proper results, if any.

Found this on the web - If you are disinfecting your water, enough chlorine should be added to provide a free chlorine residual of around 0.5 parts per million (0.5 milligrams per litre) after 30 minutes. As a general guide, an initial dose of 5 parts per million (5 milligrams per litre) of chlorine will provide this residual.

You can test this with a swimming pool test kit or dip strips, obtainable from your local pool shop or supplier. Any chlorine smell and taste in the water will dissipate after a short time.

Problem solved.

Perhaps not pertinent, but...

1) Chlorine evaporates.
2) Tygon/vinyl tubing/etc. are porous.

- It may be that the evaporation of chlorine is slow enough to not affect the biocidal affects.
- It may be that the initial concentration of chlorine isn't enough to affect any parts of your system.

Huh? As long as Chlorine is in solution it shall effect every part of a loop.

Chlorine may evaporate but so does water, anti freeze and any other chemical a user is inspired to dump in a loop.

The fact is chlorine needs to be tested in a live loop for 6 months along with some anti corrision fluid.

indeed. would be interesting to know how much clorine evaporates - id assume faster than water, as clorine has to be topped up in the likes of pools more often than the water does. Id imagine that 6 monthly water changes would be enough to stop issues, though - and you could run it at a slightly higher concentration (say, 50% again on the swimming pool dosage) - its not like you're swimming in it.

[Brians256]

What I meant is that the chlorine may preferrentially evaporate since it is a lighter molecule than h20. So, it's concentration in the water may decrease.

But, this is all meaningless talk without real testing, as you note.
