water test

[racoloish]

hi, when is that I have to check the parameters of the water? Do I have to do it before and after each water change and what time between each test?
I have to do the test weekly, how many days do I have to wait after the water change?

Depends on what you are checking for. Typically I'd test before a water change, and then make necessary changes. How long has you tank been set up? Is I cycling?

One of them is 2 years and another is 3 month. Both are cycle, I start to check because a problem I have. I'm testing weekly, want to know how many days after the water change? Right now I'm testing with the saltwater test using API.
