I have .62ppm copper--allowable level for action to be taken is 1.3
I have 4 ppb lead-------allowable level for action to be taken is 15
17.2 ppb=nickel
5.4 ppm=sodium
15 ppm=sulfate
This is what I have in my water per my city's 2005 water report. Is Sulfate related to iron somehow?
It's got to be some kind of off-gassing or chemical reaction from the ozone or the heat or both or something. I use Metal Gon. The stain is up above the water on the bottom of the spa blanket.
I do not have any brown slime or stain anywhere on or in the tub or drain. It is above, on the blanket.
I am still in one , in good health and am not quite blind
so this is not a HUGE deal--just a curiousity that no one has been able to give me a factual, straight answer for. There has been some speculation, but no real answer and I am just curious, that's all. Maybe no one knows.
However, maybe I shouldn't be breathing in the hot tub if the air coming off of it, and the bubbles popping and circulating throughout, contain poisonous, brown stain causing gasses!!
I've only had the tub for 3 1/2 months. Maybe the ozone is NOT working correctly if I have a brown stain directly above it on the spa blanket. Maybe there is a problem with the heater and it is really smoke and something is slowly melting 24/7.
Okay, I'll stop now, and Sorry Gomboman
for jumping in on your thread. I was assuming that some others would read YOUR post that may NOT have read one of mine a while back concerning this issue, and that perhaps by re-visiting it, I would get an answer.
