Phosphate Help

[bertoni]

Why do you think that bacteria are required to remove phosphate bound to the rocks? Chemically, I don't see the basis for that statement.

I have decided to make a change in my plans to test the BRS HC GFO. I swapped out my LFS' generic GFO this morning and replaced it with 2 cups of BRS HC GFO. I started thinking a better test might be to test how long the BRS HC GFO could produce a 0.00 - 0.04 reading on my phosphates since the LFS' GFO took the phosphates down to 0.00 in four days.

I'll report back what I find.
