See my post this month at
where I have concluded that the PMDD dosing regimen may be too little, at
least for potassium. I am dry dosing the PMDD components now and the tank is
doing well. I have another tank where I lived previously that is not getting
regular dosing yet, and it has a bad BG outbreak now. I am sure it is out of
every nutrient, especially N, K and trace elements.
