I tried adding nutrients, throwing in practically everything Seachem
makes. Flourish, Flourish Excel, Flourish root tabs, Flourish nitrogen,
iron, and potassium, and Trace. Also, I tried every fertilizer
separately so that I would know what had the best effect. All I got was
more algae and no better growth, although the iron did seem to make the
plants a little red. That's why I thought that something else was the
limiting factor. As for CO2, it's the same automated system that was on
the old tank: 5 gallon tank, external CO2 reactor, small Eheim pump, and
Milwaukee controller. Ph is about 6.7. The plants pearl very nicely
under all that light.

There's phosphate in our water supply. A saltwater guy who tested the
water was horrified at the amount. But I realize that freshwater is
different. Could the plants possibly be using all that phosphate and
need more? What phosphate additive did you use?
