Vodka,Sugar,Vinegar

Has anyone dosed vodka, sugar, or vinegar,  for an extended period of time?  If so what effects did you notice? I read a pretty long forum http://www.kipsreef.com/forum/showthread.php?t=318 last night on dosing these three and was wondering if anyone in the club had any firsthand experience on them? 
I've been using vinegar in my kalk for 2 weeks now and have noticed that a few issues I've had have gone away.  I can not tell by the change in skimmate though for I changed to my new DIY skimmer during the proccess.  It is working like my otherone could not. I have noticed the dark red algae on my rocks disappearing fast and being replaced with purple coraline algae.  I've also lost much of the hair algae I've had in my overflow.  My alk and calcium have seemed to be getting sucked up at a much higher rate also.  The only bad thing I've noticed is a brown bacterial mat that has grown on my sand bed.  This could be from to much to fast.

 

I don't "dose", but I do dump some sugar in every once in a while when I feed. It drastically helps with reducing nitrates (found that out with my old setup) and as far as i've seen has no ill effects whatsoever. Next time I make a batch of homemade food I'm just going to add the sugar right in.

 

I suppose I should mention the positives- when I do throw sugar in I notice less algae buildup on the glass (there's not much anymore, anyway), better polyp extension from my sps, and skyrocketing sponge growth. The sugar fuels bacterial growth, and the bacteria is either consumed by what I'm growing in the tank or skimmed out, taking their consumed waste with them. I don't see a downside aside from if one were to overdose sugar and get a bacterial bloom at night, which would drop the pH but rarely results in any losses from what I've read.

 

HAHAHAHAHAHA
I have no idea. I just shake some in from a yogurt container. Only measurement I've got for sugar, vodka, or vinegar is 1.5 oz vodka repeatedly until I'm satisfied. But that's got nothing to do with the tank.

 

I agree, go slow with any change.

Many many people use sugar/vodka. Other than bacterial blooms, which are from NOT going slow, I've not heard of any negative effects.

 

Well the bacterial matt is gone. I kept up with the same dose of 2 teaspoons of sugar and a 1/4 cup of vinegar in the kalkwasser. Becareful if you do vodka it feeds the bacteria more than sugar and vinegar does.
