I thought my blue tang was dying so I went for dosing Prazipro in conjunction with copper power @ 2.5ppm. I didn't face any major blooms and didn't have any ill effects from doing this when adding extra aeration. I will likely always do them in conjunction going forward.
11/16 was the day I began Copper Power at 1.75ppm (by 11/20 was at 2.5ppm) AND 11/16 was also the day I ended up doing Prazipro dose #1. I then did 25% water change and Prazipro dose #2 on 11/21. I did 5 days under this dosage before doing a 25% water change, and then waiting 4 days before doing Prazipro dose #3, which was conducted on 11/30.
On 12/5 I did a 25% water change and then did Prazipro dosage #4. I plan on doing a 50% water change on 12/10 completing any usage of Prazipro.
