? this article (attached pic) from TFP mentioned that to keep the CSI at 0 to -0.30 to prevent scale build up at cell plates. So you mean there is nothing to be concerned of even my current CSI is -1.21? (Refer attached pic)
Given that I have already purchased the Calcium Chloride Flake and there is no way I can return it, adding in the calcium chloride do no harm at all, at the same time, provide no benefit at all?
@mknauss now I understand! CSI < -0.6 will cause corrosion to plaster, tiles, etc, while CSI > 0.6 will cause scaling to the SWG plates. Since my CSI is -1.21 and I am having a vinyl pool, there is no issue for me. ??? thanks a lot! Now I need to get rid of my 25kg calcium chloride flakes ?
