nitrate testing
Over the past few months I have been getting high nitrate levels using api liquid agents even from my tap water it was in the 40-50 range.I decided to get my water tested profeesionally to see what is up.The fellow checked my tap water twice and it was only 2-4PPM he also checked my aquarium and got just a liitle more3-5 PPM.I've often wondered if the testing supplies we use are really that accurate.BTW I did do the tests correctly with all the correct amount of times observed and the shaking it up and such.Has anyone else experianced this?
