How to Remove Phosphates from Water and Reduce Algae

1. Initial starting dose = 1 gram/gallon.
2. Rinse all new media and place in media bag or fluidized reactor
3. For optimal effectiveness check weekly and do not allow overall phosphate levels to test above 0.25ppm. If phosphates are present and above 0.15ppm, GFO should be increased or replaced.
4. If After 24 hours there are any negative coral reactions visible then reduce the amount by half.

Pro tip: Start slowly since GFO removes phosphates quickly and effectively to avoid shocking your aquarium.
