Hi chiahead,

Your Mg is 20 ppm. If you are dosing Mg then slow down, you do not need that much. Only 2-5 ppm is sufficient.

Before you start dosing more TE to fix the problem, try 5ml SS and 5ml PF Solutions. The 8ml SS in 80gall made 0.67:0.22 NO3O4. This new dosing 5ml SS and 5ml PF makes 0.83:0.14 NO3O4. This will give you a better chance to increase NO3 in your tank which might be the cause of the deficiency.

Hi chiahead

You should flush the aquarium if your substrate leaks too much Mg, not adding more Ca.
Your NO3O4 is at 10:1.5 with 2ml SS and 6ml PF. You may try to dose 2ml SS and 10ml PF to get more NO3. If this doesn’t help then you can try more TE.
