I submitted an ATI ICP test sample because i had some Acro die off a few weeks ago. The results came back pretty much in line with the exception of nutrients which to be honest my nitrates are rarely below the mid-20's. Minor trace elements seem to be lacking but are they a reason to be concerned? I use standard IO salt and have since I started the tank about 15- years ago. I appreciate the feedback.
