 |  Kalkwasser -w/vinegar?
I have been reading up on kalkwasser all over the web. The amount of lime in various recipes range all over the map. Teaspoon per liter, teaspoon per quart, -teaspoon per gallon!
Dump out the solids on the bottom, reuse the solids for your next batch, mix only a day's worth, mix a month's worth,
AAAAAAARRRRRRGGGGHHHHH!!!!!!!!!!!!!!!!!!!!
Then I find one that says to add vinegar to prevent precipitation!
Anyone got the straight simple scoop on mixing and using this stuff? 
TANKS!

yeah, this is the one where the vinegar is recommended.
Seems counter-intuitive, adding an acid to fortify a base.
I will re-read this...

From my understanding, vinegar is added to lower the level of ph in kalk. Kalk has a ph of around 12.0 and some ppl already have their ph at a good level so they add vinegar. I, on the other hand, dont add vinegar b/c my ph is always a little low.

As lunatik 69 so nicely stated...that is the reason for dosing vinegar with kalkwasser! Lowering of the pH value of the kalkwasser solution. _________ 125gal.w/Mag9.5 return(dual megaflow)>Mag7 pump Aqua Cev180skimmer.Wave2k Hamilton Reefstar(2)250watthqi(mh)pend.a Yellow, Naso Tang Red Lip Blenny Percula Clown Demoiselles Niger Trigger F.

Let me know how that vinegar works out for you , I had a guy here to tell me a few months ago what he was going to do with the vinegar I asked why ? Seems its all the rage in some circles , Well if he See's the string I hope he chimes in and let him do all the typing .. I'll just say I would not mess with the K/W in the first place if I wanted to add Acids to off set it .
Darren if you see this chime in with what vinegar it did for your systems..

Luna | vinegar lowers the PH allowing more CaOH to be on solution. It's only needed if you are a) carbon dosing or b) cannot satisfy cal/alk demands with the typical kalk saturation levels.

You can get around this dilema somewhat by dosing kalkwasserat night time, since the pH of your tank often drops due to a stop in photosynthesis, unless you are running a reverse daylight refugium scheme. | |
