Hey all I just ordered red sea dose 4 and red sea dose 2. I know Calc alk and mag will be my main 3. What would you suggest be the other 3 most important to daily dose? Thx
Nitrate and Phospate depending on your nutrient level. Having the 2, or potentially even 3, extra dosing heads really gives you a lot of options. You can dose other elements, phyto (as mentioned above), or even trace elements such as potassium
