Review on Kolar Labs GFO - 1 lb Phosphate Removal Media for Saltwater Reef Tanks and Coral Well-being by Anna Fetzner

Revainrating 5 out of 5

Best GFO I've ever used

This stuff is amazing. I'm moving from a very expensive high strength GFO and this stuff works a lot better. The green algae disappeared after a few days. It's dusty, but I run about a half gallon through it before it hits the tank.

Pros
  • Weight
Cons
  • Definitely bad product
