I did... switched away from it after one bucket though. I didn't see any benefit from using it, and still had to buffer the Alk to get it where I needed. Also, my batch was VERY low in Mag for some reason.
In my opinion, I didn't see a big difference between adding a cap of Alk buffer to the Tropic Marin Pro Reef, or adding a cap of Ca buffer to Reef Crystals... oh except you save $40 w/ Reef Crystals.
FWIW... I now use a 50/50 blend of Instant Ocean and Coralife, and am very happy with the corresponding values I get out of the freshly mixed salt water.
