Dosing 95% ethanol for nitrates and phosphates

[disc1]

Wow, I didn't even know you could get 95% yield on Ethanol, but organic chemistry was a very long time ago. At 95% it must be sucking the water out of the air as soon as you open it.

Nah, 95% is the azeotrope point. That's what you should theoretically get out of a good distillation. Going above 95% takes extra work, usually adding benzene to the distillation or drying over sodium sulfate or something like that. But 95% is easy to get. That's what you get when you go buy pure grain alcohol at the liquor store at 190 proof.

You might want to ask for a COA on the product first. I can tell you that lots of ethanol has copper, and other stuff in it.

Anything about 195 proof is usually achieved via a molecular sieve.

I am looking to dosing ethanol. Where I work, we use molecular sieves to produce 200 proof(1% H2O or less). We produce over 300 gallons a minute, so the minute amount I would be getting is so miniscule my boss told me not to worry about it. Now I just nees to do the math to dose my 29g cube. This thread has been a lot of help.

25 liters is going to last you a looooooonnnnnnnggggg time, unless you're dosing a swiming pool.....:lol:

I realize the OP is old, but that source is NOT 95% ethanol and 5% water. The other 5% is ethyl acetate.

Nearly all high concentration ethanol is denatured. And many ways to denature ethanol. Some (like methanol) are (most likely) tank friendly. Some are not.

Thinking of using this https://www.amazon.ae/Alcohol-Ethyl-Ethanol-99-9-litre/dp/B0869FCSDY it's significantly cheaper than vodka in Dubai about 15 USD for 4 litres. Can anyone see anything bad in its contents for the aquarium?

Just be really, REALLY careful dosing that stuff. If you don't you'll have an algae bloom something fierce, like you read about....
