What dosing is suggested for medium light, co2 injected tanks? My 40 isn't really high light and I don't want to be adding too many ferts. I've got dry ferts to start but right now I'm finishing up my seachem line of nutrients. I was dosing 6x a week switching micros and macros. But I'm not sure that's even necessary. It seems my most limiting nutrient has been potassium since it's really been the only deficiency to show up after my tank was dosed every 3 days while I was on vacation. What regime is suggested for dry ferts? What do you suggest with finishing the seachem line? Thanks!
