Hello all - I'm using Seachem's Reef Builder for alkalinity and Reef Advantage for calcium but whenever I mix either - no matter how long or how aggressive, I always get undissolved power at the bottom of my ATO. I'm mixing them individually and in a separate container before adding them to the ATO. Even 72 hours later I can still see aggrigate swirling in the tank too. Any suggestions?
