    AL99 vs RowaPhos

    Hi Tim and everyone :) I am in the process of rebuilding my tank and switching to the full Triton method. I see that the recommendation is to switch between AL99 and RowaPhos on a regular basis in order for the Rowa to remove any aluminium that has leached from the AL99. My question is why...

    With regard to Po4 how low is too low?

    Hi Randy, and other Reef2Reefers. I have a problem that probably most reefers dream about having. I seem to have really low No3 and Po4 levels that I struggle to keep from bottoming out. I dose NoPox in a moderately stocked mixed reef 350 Reefer, at the level of 1.8ml daily, and maintain No3...

    Nitrates and Phosphates (Again ;) )

    It seems that the hobby drifts towards and then away from the ultra low range nutrients systems on a regular cycle. It leads the 'newbies' (of which I still believe I am one) to the incorrect initial conclusion that you need 0 Nitrates and 0 Phosphates. I have a mixed reef and endeavor to keep...

    Help with Walt Smith ReefRock 2.1 Leeching PO4

    I would like to seek help in finding the best method to remove excessive PO4 or to expedite the leeching process. I'm scared my acros will die or fear my anemones will suffer and possibly die. Any help would be appreciated. :( I'm not sure how long this process will take since it's man-made...

    Phosphate in the Reef Aquarium

    The phosphorus atom is one of living matter’s basic building blocks. It is present in every living creature and in the water of every reef aquarium. Unfortunately, it is often present in excess in reef aquaria and that excess has the potential to cause at least two substantial problems for...
