To prevent hijacking Waterbear's Borate sticky, I'll start a new thread.

Why is that?Originally Posted by JasonLion
I finally got around to adding 20 Mule Team yesterday. Started with TA of 100. When I finished, TA was 130. It is only going to go up since my water supply is very high in TA which means I will eventually have to lower it. So, I just have to ask...HOW MUCH harder to lower TA??? Is it just a question of having to add more muriatic acid to achieve the desired pH reduction prior to aeration since pH is both carbonate and borate buffered?
On a slightly separate note, great calculator Jason. My pH was only off by about 0.2 units after I finished the borate addition procedure and that was my own fault (forgot to add the last 8 ounces of acid during the second borate addition). Had I rememberd to add that last cup, the calculator would have been dead on .
