For me, the biggest problem about phosphate in a reef tank is that it can directly inhibit calcification by corals and coralline algae. From wetwebmedia.com: "The water of natural coral reefs contains very little phosphate, typically around 0.005 ppm, significantly lower levels can result in a kind of coral bleaching (Tissue cannot regenerate anymore), so this should be smallest desirable concentration. Serious decrease of coral growth was detected at concentrations above 0.1 ppm." http://www.wetwebmedia.com/ca/volume_5/volume_5_3/phosphates.htm Hello!

I am indeed not too familiar with reef tank requirements, but I remember Tom Barr saying once that his experience shows that marine algae bloom in both PO4 rich and PO4 poor conditions, so one can not say there is a direct link between those. He was of course talking about the PO4-algae equation. Why do you say that PO4 would be a huge problem? What kind of problem does it induce by your experience? Thanks for the answer.

I always keep a good level of PO4 level in my planted tank. On the other hand, levels of 3-6 ppm of PO4 would be a huge problem in a reef tank. Actually, 0 ppm would be the optimal phosphate level in a reef tank (0.05 ppm still being acceptable). Maybe I should edit that post to not fool anyone. Thanks for your comment!

" So what? PO4 in these quantities is not a problem. I'm not talking about extremely high values here. "If you have problems with phosphate..." It is absolutely not demonstrated that the presence of even 3-6 ppm levels of PO4 are a problem in fishtanks. In fact, it is desired to have around 3 PPM in the water to avoid say GSA bloom. “An other problem is that carbon carbons can leach phosphate into the aquarium water. ”
