Your water is capable of being "sparkling clean" and "crystal clear". If you can "see" the water, as in cloudy, or color tinged, like yellow or green, AND, OR, if you can "smell" your water, Test your water. Your personal senses tell you more than the test strip, which is the 2nd, more reliable, test to use.
Because test strips are not necessarily always reliable, as they have an expiration date, and expired strips may not tell the truth. Scientific, electronic, testers will tell you the answer without interpretation and are nice to use. Some use them, others don't. I will let others tell you what may be available, and the cost range, but not all parameters are measured in one tester. Some tests require “reagents” added to the test vial for interpretation.
It's like being a baker, or a grandma, they do not necessarily measure ingredients in their recipes, as they become familiar to what and how much to put in. Testing your water maybe easy for some, but not always to others because of color blindness, but you can still "see" and "smell" that water, and that is the tester you will use 90% of the time.
A Taylor Water Test Kit gives you a hands on chemistry kit that could be considered. If you use and electronic tester, you just get an immediate answer to the question without interpretation.
