Hi Shermanator, can you tell that the peak at 4 ppm is not ethyl acetate but is isopropanol?

Hi Shermanator, can you tell that the peak at 4 ppm is not ethyl acetate but is isopropanol?

It's such a small peak, looking at the spectrum I posted I cannot tell splitting. I don't see any of the other etoac peaks that would indicate it is actually etoac (neither methyl peak is there -- and if you can see the ch2 you should see the methyls). I don't see the CH of isopropanol either but it's such a small amount that would be expected.
So I still think it's isopropanol. And ethanol denatured with methanol and isopropanol in those same ratios is common (I have a bunch in my lab).
OK, thanks. I just though the the other EtOAc peaks might be buried under the other CH2 and CH3 peaks around, but it doesn't matter much anyway.

It's possible they would overlap, but perfectly would surprise me (lit values in d2o differ by almost .1 ppm so they should be easily resolved in a 500).
I agree though it doesn't matter, we are talking about very tiny amounts.
Thanks.

So, for anyone not wanting to read the whole thread. I believe I have this right:
1 part - ro/di
3 parts - 80 proof, plain, unflavored vodka
4 parts - 5% distilled white vinegar

There's an attached spreadsheet to help calculate amounts of each. Post #233. Quotes the post but the attachment didnt go with it. But you can click on the quote link to go straight to the post with the spreadsheet attached.
Personally I would choose one that does not dilute with RO/DI. I believe it causes NOPOX to have issues that others that have dosed carbon for years don't have. Like bacteria growth in the mixture and issues with the dosing line if using a doser.
I like tmz's ratio better too.
Diluting the mixture a lot definitely stopped it from working in my case. I thought the dosage would be more accurate if I diluted the product but I ended up dosing dead bacterial soup, which is not the general idea
Diluting a little may be safe but it doesn't seem worth it to me. If the dose is small, just bolus dose once a day, worst case split it in two. If the storage vessel looks clear, I'd say you're good. Cloudy => bacteria soup.
I switched from NOPOX (used for ~18mo) to tmz's recipe also. Tom's recipe seems a little more potent - I started out at the same dose I had been using for NOPOX and then backed off a little based on nutrient readings.

I'm not sure we know what amount of what is in that product, so it would be pure guessing to try to match it.
Heh, if you look back earlier in the thread you will see that we have a very useful chemical analysis of the contents. There is no mystery left as to what is in it.

When using RODI to get to the same targets as NOPOX, the end result smells very much like nail polish remover, so bacterial growth is non-existent. I mixed up 2.0L six months ago and just checked the last of my storage container. I keep it tightly sealed and it is still as crystal clear, and stinky, as the day I made it.
If you dilute the resulting mixture further for dosing purposes (which is what I think Droog had indicated he had done), this is where you run the risk of bacterial growth in your dosing container. Using at 100% strength should not have this risk.

That was a spambot copying a very early post. If you see a post with broken gif links, very small post count, odd name, and recent join date its most like a spambot.

Ok, so question. 240 gallon tank with 22 fish in it and a few more coming soon. Old skimmer wasn't working right so my nitrates got away from me, testing around 50-75 now. Question I have is if I use 1 bottle of Barton's like TMZ is how much vinegar do I add to that and where should I start my dosing amount?
Thank you,
Corey

I would start at 2ml of 80proof vodka plus 5ml of 5% acetic acid vinegar per day and increase it to 9ml of vodka and 20 ml of vinegar over the course of 4 weeks, monitoring PO4 and NO3 along the way . If bacterial blooms occur at any step ,I'd back off a bit. If not you can up it a bit more later to say 13 ml vodka and 30ml l of vodka which is about the same as I dose per gallon. Be sure to aerate well via a good skimmer. Running some GAC is useful too. IME.

thanks tom. i will read that article. in addition to those doses can i run pellets or is it not needed? i have some all in one pellets that i have access too if i chose to do so? i have a new skimmer set to arrive tomorrow. i am replacing a becket with a bubble king double cone 200.
