I recently received my ICP test results and it again show Boron extremely high (64 vs recommended 4.5). I do water changes weekly (Instance ocean) and I do not dose with any PH buffer (another source I am told). So I am trying to figure out the source so I can get it under control. The first time I got the high results I was skeptical as all my other level (from ICP test results) are very close to being correct or a little low or a little high, which is understandable. But boron is so high clearly something is not right. So any clue on the source and is there any way to lower it. It doesn't appear water changes help.
