Why not use Silver Water (coloidal Silver) instead, you could purchase or make it yourself:

Edit: I have about 4 onces of Coloidal Silver left that I had purchased a few years ago. It's still in the plastic bottle. Maybe I'll put some in different small containers and see what grows. Placing the containers in the sun should escalate the process.

That sounds like a great solution. Silver has natural anti-microbial abilities -- or, as that website put it, "1.3g of pure anti-algae/antimicrobial ass kickery" !!

I think we talked about this a couple of months ago. I have no idea what medical grade water is, but I have seen and use RO+DI water. There is absolutely nothing in it. It is almost like looking through air. I am not in Atlanta, so I can't do any basic experiments. I do know that when I worked for a bottled water company that we used to clean the bottles and machines with a gallon of water with one teaspoon of bleach. I would think that would be adequate for this application as well. IIRC, we would use a gallon of this cleaner mixture about once every couple of months.

reverse osmosis and deionized. Got a water system off ebay for $150. I use it mostly for drinking and cooking.

Does anybody what temperature does the chamber fluid get during normal operation?
I guess the three main issues are:
- Corrosion
- Fungus
- Evaporation/boiling
I *think* that with a proper treatment (e.g. distilled water with silver, possibly a drop of bleach and a nice UV light "bath" to the chamber to kill anything already floating or lurking there) fungus can be avoided.
Corrosion and evaporation/boiling.... I have no idea. I am most concerned about corrosion, as evaporation would be very visible.

refraction indexes differ more.
glycol and glycerine are closer to glass.

Agreed, beautiful country, beautiful women and a great culture. I lived there two years as a brat in my late teens in the early 90's.

So is anyone here actually advocating the use of water(regardless of additives) instead of a glycol/glycerin mix ? If so who has used it with success ?

Stefuel said it had ultra-sharp focus -- but grew fungus after a year. Hence the discussion about silver, bleach, etc.

An ultra sharp AmPro is a contradiction in terms... 
The Devil made me say that..,
 Or was that Pete ?

I don't know if anyone is advocating it, but Scott said they used it years ago with some success.
I guess the only way to know for sure is if someone else actually tries it. It would be pretty simple for most people to try out especially in the US. Aquafina is supposed to be RO+DI water. I haven't checked it with my meter, but I think it is probably close to what I use. Two quarts of Aquafina shouldn't set anyone back more than $3. For an experiment, I would put six ounces or so in a jar with varying amounts of bleach. I think a teaspoon, half a teaspoon and no teaspoon should give a good indication over the course of a month or so.

I think the silver is a better idea. Bleach will give you a quick shock that should kill anything in there, but the chlorine gets "used up" and loses its potency fairly quickly. If the inside of the chamber is sterile that might not be a problem. But with silver you have ongoing antimicrobial action for many years. Should keep anything from growing in there. Adding some silver water like MP suggested is a good idea too, to "pre-charge" the silver level in the water. If you use colloidal silver you might not need the silver coil. I don't think colloidal silver "wears out" like bleach would.

My meter tells me how much crap is in the water. I got it when I bought the purifier. That is what I was referring to when I meant measuring it with my meter.
You guys probably know way more about this than me. I will take your word that silver is better than bleach.

I just installed the green tube with water in it just to check whether there's any focus/sharpness improvement. I will do a focus setup later to determine whether it makes sense to use water or not. This is a temporary test as I need to rebellow that projector next week no mater what.

What kind of water did you put in there?

Just keep in mind hot water is more corrosive than cold and water expands more than glycol for a given temperature.
