When using the pool calculator I know it is a good idea to do all the test and have results. I am sure there are test that do not require all other test results. What are the test you can put in by themselves and what you want to get to that does not need all the other results. For example if I needed to raise my pH or lower my pH, do I need all the other results or can I do just pH levels?
Hopefully this makes sense.
