But 3ppm or more of PO4 does NOT cause algae in planted tanks! At least
that's what I've been told here when I suggested the use of Ferrous sulphate
to lower 3ppm PO4 to less than 1. I felt pretty stupid then, being lambasted
by THE fert guru:

"PO4 has been shown here and numerous other research studies that it does
not cause algae outbreaks __when growing plants__ are present....More is
simply wasteful. Above and beyond etc. "

So your statement has made my day. Thankyou. :)
