help! help! need some water?

[Travis L. Stevens]

That actually says a lot Ray. Thank you for sharing. Now, I have a question. I would like to try to measure the TDS of my Tap Water (should be about 660 ppm) and the TDS of Tap Water treated with dechlorinator (unkown). This way I can get a ballpark estimate of how much a dechlorinator actually takes chlorine out of my water, and then compare it to the report from the City of Stillwater. Then I would like to measure the TDS of my saltwater and find out how many PPM = .001 Specific Gravity. That way I can subtract my current SG to find out how many TDS are in my water. I would also have to do that with Calcium and Carbonate and Magnesium since these are the largest components of seawater; Sodium, Chloride, Calcium, Carbonate, and Magnesium.

Travis. The answer will be higher with the dechlorinator.

It doesnt remove anything, merely makes it less toxic.

 

[pwhitby]

ppm= mg/l

sg 1.020 is same as 1.020kg/l

since pure water is 1.000kg/l then you have 200g solid per l or 200, 000mg /l.

Thanks for demonstrating the conversions, Paul. That's freaking cool. I never thought about it hard enough to figure out what all of that REALLY meant...

He blinded me with Science!!!

Okay now lets talk about TAN (total ammonia nitrogen) vs. UAI (Unionized ammonia). UAI is the toxic form of ammonia for fish. Can anyone guess the other water parameters and the corresponding multipling factor to find the UAI on a TAN test??

AH, I feel like I'm back in chemisty class, what a minute, I never took chemisty!!

[captbunzo]

I would guess pH and temperature. As for the multiplying factor, I will have to pay homage to the oracle of Google first.

:lmao: I took Chemistry and was a Chemistry Aide the next year and we still didn't cover that (in high school).

 

[captbunzo]

Well, I found some conversion charts, etc, but no really good formula that I have found.

 

[Gwalker]

Yep, you got the parameters, now that should lead you to a converting factor on your TAN reading. The multipling factor is dependant on what you pH and temp readings were..........

[Gwalker]

Well here's the coverting chart for TAN to UIA readings, if anyone was interested.

Now what was this thread about?? OH, YEA water. I know where you can get some quality DI H2O..........

Travis, I am sorry but your theory here is seriously flawed. First Chlorine is a gas and not a desolved solid. With the reverse saltwater diagnosis, That will never work for so many reasons like you have no idea how much of the desolved solids are fish poop and skin sluffed off your hands and arms. Exactly what are you trying to do? I suspect you have made a simple thought into a very complicated action.

You are probably right, and any accuracy from this would be seriously flawed and undeterminable. More or less, if possible, it could be to help determine what untestable compounds are in a system. Assuming that a certain test kit is accurate, you could test enough variety of things to narrow down that X% of the TDS is actually good stuff, and the other Y% is something to be determined. Which, like you said, could be any where from fish poop to sluff off. But it could also be allelopathic chemicals from corals, toxins released from other animals, or even simple things such as ammonia, nitrite, nitrate, and phosphate that your test kit might be giving an inaccurate result. For example, if your test kits, accurate or inaccurate, can compensate for 95% of your total TDS in your water, then I would say you have pretty sterile water. But if you are on able to test 70% of the water, then there is something in there that is taking up a lot that you can't test for. Now to determine if it is safe or hazardous would be a whole new ballpark.
