So I have setup my 75 gallon with sump approximately 60-70 pounds Marco rock and 80 pounds live sand. Dr Tim’s ammonium says 4 drops per gallon to get to 2-3 ppm not to exceed 5 ppm. I did this and checked after about an hour with pumps running. It was at .5 ppm anyways I put enough for 100 gallons and it only ever got to 1ppm. Am I doing something wrong?
