Is it ok to add All For Reef to a mixing bin? I do daily water changes via an APEX DOS, set up to change 4Gal / day on a 300Gal SPS tank. I use Tropic Marin Pro salt however my last ICP test shows I'm low on some trace elements so was wondering if I could add some AFR to the 100Gal mixing bin to sort of 'top off' the trace elements in the tank? If so any idea how much I should add from a dosing POV? Thanks
