Do you need to mix salt into tap-water to check the test? Or do
ammonia tests work for both Salt and Fresh Water?


I don't test for ammonia, but I think it highly unlikely that your tap
water is of such poor quality that it has ammonia in it. According to
the Hagen web site, however, they sell different ammonia tests for fresh
water than for salt. If you wanted to test your tap water with a marine
kit, you could test water that you mix up for a water change before
adding it to the tank. The nitrite, nitrate, and phosphate test kits
work for both fresh and salt water.

All successes in conservation are temporary. All defeats are
permanent.
If they add Chloramines to the water it will test for ammonia, since
chloramines are a combination of chlorine and ammonia for disinfectant.

Personally, I use RODI water and would recommend you to also get one.
Remember this; it all starts with the water. If you pick one up, wait until
you need to do a partial change to intoduce the RO water into your tank. I
got mine from eBay fairly cheap (compared to some of the on line stores)
Good luck
