Review on Accelerate Algae Growth with CaribSea Purple Up, 16-Ounce for Stunning Results by Rich Fiedler

I had a lot of green algae and as soon as I started using it I noticed a change almost immediately. My pelvis is getting more colorful, but there is still a long way to go. That alone isn't enough, you still need a solid refugium/filter setup, but this stuff definitely helps. I currently use it about twice a week so the bottle lasts a long time.
