Need suggestions for good nitrate and phosphate test kits please.
Right now I am using API, I tested the amount of nitrate in the tank a day after the 2nd dose of ferts for the week. It showed it at 0ppm. Keep in mind that i use the ei method and actually put in 1.5 tsp's (about double the amount for a 75g) per fert dosing which i do 3 times a week.
I mixed .5 tsp of potassium nitrate in the amount of water that would fill a small disposable bathroom cup and test that, it only came to 5 ppm. I would think it would be off the charts. This has lead me to believe the test kit is faulty.
Mind suggesting any other companies which have given you good results?
