calmag plus

yes thats what i do, sorry i thought this process was called distilling water

Nope, all that does is allowed excess gases that would be dissolved at cold temps, and compounds that would be liquid under those conditions but would be gases under normal atmospheric conditions, to evaporate off.
Dissolved minerals do not go into gaseous forms at room temperature, and therefore remain. To truly distill water, you must bring it to boiling and then re-condense and collect only the pure water fraction.

wow ive been thinking like that for quite some time thanks for clearing that up. So i guess it is still a good idea to let it sit for a few days?

If the water has been distilled, then by definition, it does not contain useable amounts of any minerals.
Yes, you need CalMag if you are using distilled water.

I didn't know what distillation filtered out as compared to RO. Now I know..

Ideally, the end product of distilled water would be the same as the end product of RO... but since the distillation process involves plenty of contact with atmospheric gases, which become dissolved in water (the levels depend upon the temperature of the water and will change over time as it sits), distilled water DOES have substances in it that are not H20.
Dissolved Oxygen, CO2, and N2 are present in distilled water, adn go into various equilibria in the solution.
However, CaCO3 (limestone), which is very very common in tap and surface waters, is removed, since it cannot vaporize at water's boiling point, which brings us back to why you need CalMag if you are running any type of purified water.
