If you get a master test kit you should test your tap water. I was a level 3 state liscenced water treatment technician for the company I just retired from. We try to keep tap water at 7.2 to 7.4 pH to prevent corrosion to city lines and house plumbing. But cities may be higher due to the area geology. The other thing to test for is nitrates and possibly Phosphates(Only pertains to algae growth) and degrees KH (carbonate hardness)
Chlorine and chlorimides are detoxified easily with dechlorinating water conditioners.
If your tap water is 6.8 to 7.6 and your nitrates low and your dKH is from 4 to 8, your water will be great to use.
I put my water for changes into a small tub, put in a little 50w heater set to my tank temp, put in a air stone from a small cheap air pump, the declorinator and thermometer and let it sit overnight to degass/oxygenate the water.
Hope this helps. It makes life so much easier if you can use your city's water.
Caudially, OS.
