Iron and algae
<< I seem to get good growth but have problems with algae (the short green
hair stuff)if I attempt to push my iron, and/or nitrates to the
recommended levels. >>
I had this very problem myself until I recently started adding mono-basic
phosphate or KH2PO4 at . 5ppm up to . 8ppm. Then the BBA disappeared, and I
mean vanished, whereupon my tanks started soaking up N like crazy and allowed
me to add all the iron I wanted without additional algae problems.
I too thought the plant were growing just fine -- but its all relative. Now
they are doing even better with denser growth and better color overall.
I say all this as I notice you list P as zero so that may well be the
problem. That DIY CO2 is a real hit and miss thing too, IMHO, and perhaps a
contributing factor.
PO4 is inexpensive but the test kit is not.
