*although it removes phosphates* Kent's Phosphate Sponge isn't GFO (granular ferric oxide). It's an aluminum based PO4 adsorber.

IMO/IME Rowaphos is as effective (or perhaps even more effective) than the GFO BRS sells simply because it has more surface area by volume. It's a finer sized GFO.

Cheapo flake foods can contribute significantly to a phosphate problem.
