You dont test with freshwater.. you test with test kits. But to clean equipement use a little vinegar and water but never use vinegar on a impeller that goes into a pump because the magnet will expand and warp inside the pump when you return it back to the saltwater. Just use water and a brush to clean things.
I always just use normal tap water, let it run for a few days, empty it, then let it sit for a little while and add your saltwater. The concentration of anything nasty you got out of your tap water, will be extrememly low. Also, many of the chemical additives percipitate out of the water (i.e, they evaporate a lot faster than water).
