im sure you can get ozone out of a cigarrete too colesy, i mean ozone is a secondary pollutant from car exhaust + sunlight, so tar and other carbinacious materials in cigarretes probably can make ozone too...
Is the .08 ppm number applicable for prolonged exposure or for short term exposure?
Long term prolonged exposure, as I understand it, but the whole study is not yet published.
r you saying that the sorce of this ozone can be from the heating of a home?
I'm not sure who you are asking, but it can't come from any normal heating system.

You also need to pass the water out of the skimmer trough activated carbon. A god sized bag of Carbon in the sump before returning to the tank shall do. Note that you may still have some in the bubbles that come out with the water, I try to minimize it covering that section of the sump.
you talk about filtering the exit air from the skimmer.. i have carbon on my Collection cup.. but wouldnt you get some that escapes through the water exit?
That can be a significant complication of using a skimmer (at least some skimmer designs), IMO. I choose to use something different (an ozone reactor), where I can easily pass all of the water and air over GAC.

Randy, it seems that from what I've read, detectable levels by human noses are about .003. Thats like 1/26th of .08. So at prolonged exposure to 24 times the detectable level, there is a .3% chance in early death?
So to get a 1% chance of early death, you need about 75 times the human detectable level? That doesnt seem like a big deal to me... I'd think at 75 times the human detectable level, no one would be able to stand the smell...

Why would you suppose that if you smell it, that it is just at the lower limit of detection? During a stage 2 smog alert in LA (1 ppm), people are not walking around complaining of the smell.
In some ways of using it, my whole basement stank. No GAC on the air output, for example. I'm sure the levels were above the minimum for detection, especially near it.
Anyway, my concern is really for the folks that report routinely smelling it, and may be using it in their living rooms, not for folks using it in a basement, and who can barely detect an odor when sniffing right at the output (which is how it is in my normal operation).

ok sorry i dont have time to read back but you guys speaking of our tanks and equipment possibly giving off ozone?
No. Ozone generators giving off ozone.

if your whole basement smelled strgonly of it, the air would be blue, O3 has a blue color, and is easily broken up by CFC, chloroflorocarbons, which were foudn in old aresol cans, by cholrine, or bromine, those simply creak up O3 into O2 and O, but bromine and chlorine are A. both bad for you, B. cause wholes in the ozone layer if concentrated enough, after time, but i dont think ozone is a good idea. Its also very flammible, so you are luck your house didnt blow up when your whole basement smelled like it...
still i wouldnt trust it

Just a couple of notes here.... I understand that by the Montreal protocol, CFC production has been phased out in most of the world.
Also It is sometimes a misconception that Ozone (as well as Oxygen) are highly flammable. The gases themselves are not flammable at all but under certain circumstances can support combustion of materials that otherwise would not be flammable in normal air. When in contact with materials readily flammable like oils and grease the reaction is so fast that can turn explosive.
if your whole basement smelled strgonly of it, the air would be blue, O3 has a blue color,
So you think that I either am making up the smell, or didn't notice the air was blue? :lol:
Trust me, the air can smell of ozone without turning blue.

no no no im not tryign to call you a liar, im jus tsaying i thought you sed it smelled really strognly of it, i would have thught it would haev turned blue, but yea im sure it can.
if i smelled ozone that strongly i would have turned off all pumps and anythign electrical, even a thermostat, eve na small spark can set it off, very flammible

A few ppm ozone is very toxic, stinks, is not blue by eye, and is not going to ignite.
Bear in mind that the blue ozone liquid is abut one billion times more concentrated than 1 ppm in air.
