You should address the alk level separately and keep it stable with AFR!I went through the powder quickly and my ALK dropped from 8.3 to 7 and could not get higher once I switched from liquid to powder. I dosed more and more no luck.
I gave up on it and am using Reef Builders but now. ALK and Calc spiked to high; just can't win......LOL
