Using Ozone to reduce chlorine

Split by moderator from HERE. Please start your own thread for you questions. Thanks, jblizzle.

I am learning about ozone to assist in reduction of chlorine because:
* The burning it causes, when using a mask the build up after a couple of hours is not acceptable
* Dry smelly skin
* Dry coarse hair

Have to raise a hand to Waterbear's scaring post.

... according to OSHA, 10 parts per million is considered Immediately Dangerous to Life, requiring urgent evacuation ....

Your quoting ppm figures that is related to ozone in the air. Ozone dissolved in the water is entirely different.

Re: salt water vs. ozone purification

Welcome to tfp, Tfar Craw

Ozone is not needed in a typical outdoor residential pool. Now to your reasons you stated:

* The burning it causes, when using a mask the build up after a couple of hours is not acceptable

I am sorry, but I do not understand this...do you mean burning inside a swim mask?

* Dry smelly skin

* Dry coarse hair

Properly maintained chlorine levels will not cause this. Much of the problem is people take from their experiences in public pools (or improperly maintained private pools) and assume that this applies to all pools that use chlorine as a sanitizer. In fact maintaining the proper FC level for the pools cya level will eliminate these problems. See: http://www.troublefreepool.com/pool-school/chlorine_cya_chart_shock

If you are assuming ozone will allow you to not use chlorine, then your assumption is dangerous since there is little residual effect of ozone in the water.

Poor pH balance will cause stinging eyes and hair issues also.

You might be a candidate for a SWG. Salt pools are still chlorine pools, but can be maintained with higher CYA and lower FC levels, but are still safe and sanitary.

But if you don't keep pH in balance, you'll still have stinging eyes and such.

Ozone dissolved in the water is entirely different.

While ozone is different in the water, it doesn't tend to stay in the water. If ozone is allowed into the bulk pool water it will end up in the air and soon cause respiratory issues. Pools that use ozone normally do so in a separate mixing/reaction chamber, where the chamber is specially designed to insure that the ozone has broken down before the water exits the chamber.

Also keep in mind that the way we manage chlorine we are already reducing it considerably through judicious use of Cyanuric Acid (CYA). The minimum FC/CYA ratio that we recommend has an active chlorine level equivalent to only 0.07 ppm FC with no CYA. Compare that against public pools with even only 1-2 ppm FC but with no CYA -- 14 to 28 times as much active chlorine.
