    Haha sorry I was unclear. I was referring to the growth on the right of the torch coral. The whitish part seems like some sort of skeleton.

    Over the past month, my torch coral has been growing something. Not sure if it will eventually become a new torch colony though. Just thought of sharing something that might be interesting.

    Phosphate and Nitrate relationship

    Biologically, nitrates and phosphates are used up in accordance with the Redfield ratio. That is, carbon: nitrogen: phosphorous, 106:16:1 ratio. So having zero phosphates would indeed make it harder for bacteria to reduce nitrate. However, it is usually the case that zero nitrates detected on test kits merely indicate that the levels are low, rather than phosphates actually being completely absent. The biological process should still be occur.

    That being said, since this form of reduction of nitrates and phosphates occurs biologically, it should not affect the ability of purigen in removing nitrates.
