gust check dosing pump,
I know JL, ocean aquatic and so sell them,
you have to lock at the ML/M, and se if you find one that douse exactly that.
the thing is, thy are static, so if you buy one that dous 5 ml a m, than thats it, you cant increas it
unless you put it on a timer and run it several min. a day, but think this wil not work for you
