one year, exactly (new plumbing went in a few months ago)How long has your tank been up?
Have you put in any live rock?
Do you do regular water changes?
No, all the rock started dry
before this issue, I had not changed water for 3 weeks because I kept bottoming out phosphate. before that I did 10% weekly with Brightwell neomarine and I have done two 15% water changes since sending out this test
