Macroalgae Nitrate Export

[Megalodon]

GFO is so expensive though. I'm trying to wean my tank off it with chaeto however phosphates don't appear to be consumed as readily as nitrate. I hear it's the same problem with a carbon source, the bacteria consume nitrate and phosphates in a ratio that leaves excess phosphate. There's some reefers recommending to go back to bio balls because of this, LOL. I'm not sure if this is true or not. Oh well, GFO stays in my tank for now. So does the chaeto.
