Simply dip a strip into your water and swirl two times, then remove the strip and hold flat to evaluate color changes. After I came back from travel and was doing WC day, when I tested this past weekend tank came up 0, I tested three times in 3 tubes to ensure I was consistent and all were 0 or light blue.

API® FRESHWATER MASTER TEST KIT will enable you to test the pH levels in your water as often as needed! What I have gathered is these things are wildly inaccurate, the color-metric scale is hard to read for most of us, but I did test my water for nitrites back to back to back to back and even swapped the test tubes to ensure it wasnt some kind of contamination.Replacement test tubes are also available for purchase from online retailers, should you need additional test tubes.

This will make sure that the reagents don’t cause anything to stick to the sides of the test tube, which could cause staining over time. General Hardness, pH and Alkalinity values are useful tools, but again, these parameters are innocuous in-and-of themselves.The test also contains a complete, step-by-step instruction booklet, including information on how to correct any potentially unsafe water conditions, should you experience this. I've recommended a drop checker (a type of titration) and conductivity meters because they work in nearly all circumstances.
