I bought my at OC.

What is your nitrate level? Biopellets consume both nitrate and phosphate at a ratio, much more nitrate than phosphate. I don't remember the exact ratio. If you nitrate is undetectable, then you won't be able to lower your phosphate using biopellets alone. There are some speculations that using GFO will hinder the effectiveness of biopellets, but nothing scientific. If you want to try it, go ahead. Make sure you measure both nitrate and phosphate at the same time.

0, zero, zilch, nadda, zip! Always has been, hopefully will always be That's with 4 tangs,2 clowns, 3 leopard wrasses and 2 anthias in a 125. Nitrates, 2 to 5ppm just before a water change, and I feed my fish very well.
