which test, the powder test or the liquid test is more accurate? is this a good test to use for nitrates? i'm testing now and didn't seem to get the powder one right. i got 100+ ppm for the powder test and what looks like 10 ppm for the liquid? can anyone help? thanks. <img src="graemlins//confused.gif" border="0" alt="[confused]" />
