Can someone explain to me in stupid people terms what my test readings should show after a 50% water change?
I understand the process a lot more since visiting this site and reading the links and articles. But, I want to know more specifics - numbers wise.
For example, I did a change around 5pm and tested about 30 minutes ago (so about 7 hours later). Everything was basically the same, the pH dropped a tiny bit (the city's water is acidic) and, ammonia still at .5, nitrites at 0 but the nitrates raised to 5.
Is that usually what happens that long after a change? Is it usually more? Less? I know 5 is still okay, but knowledge is power.
