I just wanted to clarify not to use vinegar. You did not clarify why not to use it. No need to quote the rest of the post as there was no context on why not to use it.
If you knew it already, why suggest it?
Obviously because it is a way to quickly and easily lower alk.... and that was the question. Yes in time it goes back up, but it can be used when you have skyrocketed your alk and want to get it down immediately. I have used it myself during a doser mishap and it works quite well. In the same way kalk dosing increases ph..... but it will go back down unless continually dosed.... yet kalk (and other alk additives that have a ph increasing effect) are still used for their impact on ph. The fact it is not permanent was not an essential piece of the equation.
The reason I suggested just WC is not because it does not work, but because it is the better longterm solution and someone very new is probably going to cause more problems than solutions if trying to control high alk with vinegar. There was no reason to turn it into a chemistry discussion though.
