Nitrate Levels (when it's safe to make a water change)
I went and bought a nitrate tester (API brand) and I did exactly as it told me to do. I got a reading of 10ppm.
I thought it would be a lot higher as I have not changed the water in just over 2 weeks. I have been told that it climbs over time and that I should keep it under 40ppm)
So is this telling me that I don't need to do a water change yet? It seems like this reading is very good.
(Side note: Making partial water changes can also help to reduce nitrate, however because many tap water supplies contain nitrate, it can be difficult to lower nitrate levels by this method.)
