Kalkwasser & Vinegar...

[cbianco]

When you mix them you are making calcium acetate. The acetate is a good carbon source for bacteria which will reduce N & P. Very similar to dosing vodka, sugar etc. After awhile you might see zoo's, softies etc. not doing so well and then you'll need to back off for awhile. That's what happened to me. SPS shouldn't mind the low nutrient environment though.

I was using only about a tablespoon of vinegar, just enough to get the majority of the kalk to disolve. Does the amount of vinegar affect the amount of acetate created?

You really need to keep a close eye on your Ph when adding vinegar.

Will my pH be affected by such a small amount of vinegar? Does the acetate created also affect the pH?
