FAQ: The Seachem Focus™ package instructions say to use 5 scoops and your website says to use 1. Which is correct?

Both!  You can actually use anywhere from 1-5 scoops of Focus™ per 1 Tbsp of medicated food blend.  1 scoop is sufficient to bind medication to food, while 5 scoops will maximize the antibacterial properties of this product when used alone.
