Leaching phosphates from rock

[Reef Pilot]

Use MB7 to out compete cyano. Works very well in conjunction with bio pellets or other carbon dosing. And makes your water crystal clear.

Use Foz Down to leach out phosphates from your live rock and sand. But be careful, because if you lower your phosphates too rapidly, your corals may not like it. Once your phosphates are close to zero, you can maintain with GFO. I did that with a tank early last summer, and it worked very well.
