hello all! so ive got a four pump doser and im getting ready to set it up. im planning on dosing calcium, magnesium, alkalinity. Do you recommend I dose something else in the fourth pump or modify my current plan? also, what are the most economical brands of additives? I appreciate any help as I am new to the dosing world.
I plan on having lots of SPS and LPS
