TL;DR: Can I mix up Balling Part C such that it has a 1350 Mg and 400 K when diluting for salinity increases and only use when I dilute the tank (rather than dose it daily)?
I have a 20g nano mixed reef that is about a year old. The frags are becoming small colonies now, along with coralline all over the rock and back of the tank, my alkalinity demand has increased over the past 3-4 months from 0.4 to now about 0.5 dKH per day. I'm using 2-part. Though I only recall having to do a dilution twice so far (maybe 3 times?) to bring salinity down to my target of 1.024, as I increase my Alk/Ca dosing the dilution is expected to be more often. Now I'm considering the addition of Balling Part C.
For example, to bring down the SG from 1.025 to 1.024 I'm replacing 1 gal tank water with 1 gal RODI. Can I just mix up Part C to the target level (assuming 1350 ppm Mg and 400 ppm K based on Tropic Marin's recommendations for where the tank should be) and use that instead of plain RODI, or is there a benefit for dosing tank daily with the 2-part? I'm testing Mg monthly but I don't test for K. I only dose Mg to my saltwater mix prior to a water change to bring it up to 1350 and to make small adjustments to the tank itself based on measurements.
