Algaefix experiment

[tim_s]

Well we can prove this wrong,

I imagine if you had enough phos. to cause a major algae outbreak it would be detectable but depending on your corals (ps. I personally have not seen any bad results but some people have reported phosban effecting corals) you can add phosban.

How large are the live rocks?

If you dare or have the capacity you can take one of the larger rocks and rest it within distilled water. You will have die off but Phosphates should collect if your theory is true.
