My only fear was there problably are bacteria or other microorganisms that use acetic acid for food. Still not clear if these live in aquariums too.
Apparently everyone knows vinegar is useless but nobody can tell why… [/quote]
I thought I answered this already …..
What I found is that the bacterial flora will increase within a few days, because the extremely short-chained organic acids of vinegar are easily to be consumed by bacteria.
This was the experience made with vinegar in aquariums …… no question that the bacteria must have been there ………
