If your Alkalinity is 330 you wanna get that down, A LOT. You want it to be around 80-120. When are you expecting the K2006? If you're using strips to get your readings I'd wait till you get the K2006 and retest everything as the Taylor kit is much more accurate than strips. But if it is indeed that high you'll want to get some muriatic acid to lower it, this will take some time though because the acid will also lower you pH. So you'll have to add acid, aerate to raise pH, add more acid, etc. Until both your pH and TA are in range.
