Honestly I havent dosed them in awhile but when I was dosing I was using around one drop a day. I still dose strontium occasionally but stopped dosing the lugols and AA. I have come to realize that my tank will never really be a ULNS and require them. I am kinda of lucky in that I have found a good balance between feeding Rods food and biopellets/GFO. One of the blue stags in the tank is a great indicator coral for me in that it will get darker and the polyps will turn green when I need to change the GFO.
