[AGA-Member] Sechem Flourish Nitrogen

["Paul Byham" <plbyham@bigpond.com>]

Hi, Can anyone answer a question about dosing with flourish nitrogen. When I dose my 34 Gal tank with the calculated quantity of nitrogen to increase the nitrate level by 10ppm and I test it later in the day with an Aquarium pharmaceuticals nitrate test kit it tells me the nitrate level is only 5ppm. Has anyone come across this before or is it a problem with the test kit? The tested nitrate before adding the nitrogen is 0ppm. The formula on the bottle said to increase the nitrate level use the following equation 0.05 x Tank volume in gal x desired nitrate increase - 0.05 x 34 x 10 = 17ml or have I read the label wrong.

Thanks.

Paul B
