If i wanted to add sugar to vinegar in order to make the vinegar twice as potent for a carbon source, how much sugar would I add to a 4 liter jug of 5% acetic acid?

Not a chemist but sugar is 42.11% carbon acetic acid is 39.99% carbon. Think you could roughly follow the directions for making a 5% dextrose solution of 50ml per lt of water.
I will say as a bee keeper, sugar water with low sugar content has a very low shelf life. Unsure how the salinity of acetic acid would enhance it. But in the early spring, when temperatures are still low I begin to see bacteria spoilage around 1.5 weeks, with less sugary mixtures. And i stay at about 50% dilutions during the spring.

Very roughly, 50 grams per liter.

Vinegar is acidic enough to prevent bacterial growth.
I am curious as to the amount of sugar people are using to carbon dose that run sps tanks. I know it can cause issues if using too much but It seems not many are using sugar. I thought I remember reading that a small amount of sugar can be beneficial because corals can use a small amount of it or something?
Curious about all this because I have been using vinegar for a long time and am dosing about 175 ml a day in my 100 gallon system. Pretty sure this is a lot more than most people use and I don’t want to add vodka to the mix of I can avoid it.

Thanks guys!
Could I add any of these:
A pill of chelated (hydrolized vegetable protein) managanese to the vinegar/sugar mix?
Iron chelate (DTPA)
Also can i add a pill of magnesium/potassium aspartate to the vinegar?

my one experience with sugar was poor. It browned corals in my tank.

What corals got browned?
Do you know if i can add those to the mix? Mostly id love to dose iron and manganese in there. Id add very little though.

It was a very long time ago and I can't find the original posts on it, and I also had a second experiment where adding iodate browned corals, so I may be confusing them, but I seem to recall it was SPS and green mushrooms that turned brown, presumably from excessive zoox.
You may be able to put iron and manganese in a vinegar solution, but it may be prone to air oxidation after high dilution in any solution.

Okay. Thats a good or bad thing about the browned corals?
I added 3 pinches of iron, 25mg of manganese, and 3 capsels of L-aspartate to it. Mixed very easily all of it dissolved.
Im not sure what you mean by after high dilution in any solution.

I thought it was undesirable and never dosed either compound again.
When there is a lot of ferrous, Fe++, iron in water, if a little O2 gets in, it can only convert a small portion to ferric iron. If there is not much iron there, and the same amount fo O2 enters, it might be enough to oxidize all of it to ferric iron, which is less soluble.
At the low pH of vinegar, even ferric iron will be soluble, so it may not matter, at least for iron.
