questions on GFO

[philipph]

Here are a few questions regarding GFO use.Would I starve my corals if i'm using GFO to keep undetectable levels of phosphate constantly?if i choose to keep phosphates just above zero,like 0.04ppm how important is it to keep that level stable and prevent it from fluctuating?and finally,if i choose to keep my levels really low and stable what is the best way to achieve it,adjusting the flow of the reactor?thanks..

1. No, you will not starve your corals by reducing phosphate. Phosphate levels on a healthy natural reef are lower than we can achieve even using GFO in a closed system. The idea is to let the foods you add provide the phosphate needed to keep corals alive, not decomposing waste or tap water impurities. That said, if your corals have become accustomed to very high phosphate levels, some can be shocked by rapid removal when GFO is first employed.

2. No matter what you do, Phosphate levels will vary slightly over time (like after feeding). GFO simply keeps it low enough to prevent phosphate from fueling hair algae growth or impeding calcification.

3. You keep it low by replacing the GFO every month or two. Flow through the reactor should be maintained around 100GPH to keep the GFO from escaping the reactor or being ground into dust.

this is what i wanted to know,thanks a lot..

once the level of phosphate in the reactors effluent starts to raise, then swap out or replenish the GFO
