Vertex for me. But just as with ich prevention and cure, if you don't do it right, lots of problems. However, if done right bio pellets are wonderful.
I inherited a very mature tank (10 years old) a few years ago, that had high nitrates (up to 100 ppm), high phosphates, and full of algae, detritus, and cyano. With the help of bio pellets and MB7 (a must IMO), it's been running clean for some time now with zero nitrates, near zero phosphates, and no algae or cyano problems. So the bio pellets definitely work, no question.... And my SPS is growing nicely.
