How to measure KH,GH,CO2 in ppms?
I just bought some test EQ from AP, but I'm not sure how to read the readings and also where I get a CO2 test kit? I read in this forum that people write down "I'm using 30ppm of co2......"
I got a CO2 indicator from Red Sea but just tells me with a color measure if the co2 leaves are safe. Also, I got the KH and GH test kit from AP but I'm sure how to read. This is what I got
Supposedly I have to count the number of drops than read the table to get the number. For my KH i got 5 Drops until the color change and the table said that is equal to 89.5 for the GH 8 Drops that means 143.2.
Is that means that my KH is 89.9ppms and my GH is 143.0ppms????
Also, Where can i get a CO2 test or indicator in ppms?
