I think I'm going to use half what the recommended dose is to start.

or cut out/back the gfo and water changes for a bit ;)

you can attack this from both angles fwiw:)

So this seems to be a great thing for heavy feeders.

I'm thinking I will try this in the near future.

Perhaps using a doser would make things simpler. Am I correct? Do most of you use one?

I already cut my gfo back to about 1/2"-1" of the canister. I change my water about once every 1-2 weeks. Will this mean I will only have to change my tank water once a month?

Yes auto doser is prob one of my best investments next to a auto top off. Too bad mine only pumps 3 things and I use it for alk ca and mag like most do. Guess I will have to manually dose the VV

Is vodka (carbon) worth doing on a small tank? Is it similar how carbon helps freshwater plants thrive?

It might be easier to manually dose the magnesium. You could probably get by with dosing once a week

Yes, if you need it. Sometimes you do, other times you don't. My 180 had 0ppm/0ppm with no carbon dosing. I think if you have a fully loaded tank, the corals use up the excess.
With my current tank, rock was leaching, so I found it useful. Once I rebuild next week, I won't dose unless/until I need to.

No, I joyfully threw the GFO bill and reactor to the curb a long time ago. Foz Down all the way!!!

I use a peristaltic pump with a multi timer that runs for 7 mins 6 times a day.

Does anybody know the quantity of each if I were to dose just vodka and vinegar?

Just use the same as you would with VSV, skip the sugar. 4:1 vodka:vinegar.

Thanks brad. You're a useful bloke to have around here!

t thought you wanted more vinegar than vodka

This was the basis for my batch

Today is my 3rd day of the VV mixture. I will take before and after pics so u guys can see if it works or not

Interesting, with that mix you're getting the vast majority of organic carbon from the ethanol. I think there are many ways to skin this cat, but one thing is clear, it works!

Ya, and I was originally just going to use vodka, so it being the largest part isn't a concern
