Currently I am using tap water, EC around 0.3 and PH of about 8.2, which I adjust down using phosphoric acid.

I am considering the purchase of a RO filter system for drinking water, and of course the garden will benefit as well. Has anyone had any experience with how RO water changes the PH of their tap water, if any at all? I'm just curious before buying, I suppose I can also ask the company that sells the RO system.

Here is the system I'm looking at (please let me know if you know of something better!):
