what kind of rocks were they, the dry rocks? Just curious, because I just ordered 50 pounds of the dry Tonga shelf, and if they're creating high phosphate levels, that's good to know in advance!
I had two kinds ffrom marco... Shelf and figi. I think the problem was, that I didn't cook them long enough so they are finishing in my tank.
