I keep seeing seeing what different things need to be at ppm in my tank. I know it means parts per million. For example, if I need to add ammonia to my 10 gallon tank to raise it from 2 to 4 ppm while cycling, how much do I add ? How do I figure out how much a ppm is ? My tank has been set up since 2 - 27 -24, starter dose of 5cc Seachem Stability then 2 1/2 cc for 7 days. 3 drops of ammonia every other day. I tested everything yesterday with the API liquid tests. nitrate 160, nitrite 5.0, ammonia 0, pH between 7.6 and 8.0 . Do I leave it alone for a couple of days to see if the nitrate and nitrite levels start to come back down, or do I need to add more ammonia and how much ? The add x amount ppm is what I don't know how to figure out. I need it say something like.....if ammonia is at 2.0, add 6 drops of ammonia to bring it to 4.0 in a 10 gallon tank. Sorry, I'm really math stupid.Also in the attached pic, what does ppm 60s and ppm 15s mean on these test strips ? Using these, the nitrate was 250, nitrite 10, and pH 8.0
