You will be hard pressed to find one superior to the Seachem. It's a dandy.

This question came up a couple of weeks ago, and everyone had a different
answer. All the phosphate absorbing products made from "white granules" are
aluminum oxide. All the products with "black powder" are using iron oxide.
I like the Phos-Zorb pillow (white granules) simply because it comes in a
ready-to-go pouch. Plants also absorb phosphate, so a sturdy stand of
growing plants should remove any phosphate you might have in the water.
