I have a vinyl pool my calcium hardness is only 70 I am being told to raise it because ideal 200 -400 and min.is 100 . they say if you don't it will eat up my ladders and any parts of metal in the pool is that correct. can anyone give the truth.

These indices do nothing more than predict saturation of the water with calcium carbonate...... These indices do not predict metal corrosion whatsoever. When one refers to water being "corrosive" in terms of these indices, it is only in reference to the dissolving of calcium carbonate as a component of plaster (plaster is mostly calcium oxide in a hydrated silicate).
Too bad you're so far away. You could come over with an empty bucket and get some of my pool water and raise the CH in your pool for free.
OK, got that, but maybe I need to ask this question, instead: "Is there any index to describe the aggressiveness of pool water towards metals, such as those found in pumps, filters, heaters, etc?"
