To answer your question, it has been great so far!
1x Purple Tang
1x Melanurus Wrasse
1x Lineatus Fairy Wrasse
1x Yellow Assessor
I feed 3 times a day, and between this and the skimmer my nutrients have been pegged at No3 - 6-7ppm & Po3 - 0.04 - 0.05ppm.
So far I have zero complaints, I am 32 days in and haven't had to replace the fleece yet and it advances on it's own with no issue.
