yep, regular io and i dose coral vite for the trace elements, i am also now experimenting with (2) products
az-no3 which removes nitrates
and po4 out which removes phosphates
cant get trates to below 5 to 10 ppm
and since i didnt cook my rock i got a shedding prob causing excess phosphates. now i have a nasty little outbreak of hair algie. i am really getting into sps but i have to get all of this under control before I make the investment. darn buggers are expensive and i dont want to weeds to choke em out.
i suppose when my cal starts to be sucked up by my future sps i will be dosing kalk too. a reactor is just too much $$$ at the moment. Ill have to keep it old school.
