Long story short my PO4 has been hovering around 0.11 and just beat a GHA problem and added GFO last week to bring down to 0.05 range. I have test every other day.Since 3 days back has been at 0.02 on the hanna tester. Now the question is should I reduce the amount of GFO in half and hope that it slightly raises and maintains it there or take the GFO offline? Also what coming out of my GFO reads as well 0.02 does that mean it’s depleted?
