Here's another one:
If testing for KH with the Api test be sure to bang the heck out of the bottle:
Test 1 that I did not banging it:
Drop1-yellow
Drop 2-20 yellowish gold
Test 2 after shaking and banging the bottle:
Drop 1 - blue
Drop 2- light geen
Drop 3-Yellow= 53.7 ppm
Note that there is only 1 bottle for this test, but everything must of been stuck to the bottom of the bottle in test 1 from above
According to the instructions that came with this bottle. It states that your first drop should be blue and count the drops you place in the test tube til it turns yellow and then check the chart corresponding with the number of drops you added. This will give you your Carbonate Hardness (also known as Alkalinity). Aquariums with a very low (under 50) are subject to rapid PH shifts if not monitored carefully.
Hope this helps
