i put medifin in the pond a couple of days ago as i had a fish with a tiny white spot on his tail fin early in the year ... its all ok now, but it said to use as a preventative to use again in the autumn ..so i added correct doze ... next day i done my water test ... and both my nitrate and nitrate have gone up ..i test this ever week and its always been low my question is could it be the medifin giving me a false reading or do i have problems ?
