Mike,

I pretty much follow the Dupla recommendation for the drops and tablets.
This gives me an iron level that is barely detectable (measured with a 
test kit by JBL). I would say the level is somewhere around 0.03 mg/l.

However, I do have a thread algae problem. It's under control and stable 
(the last two months or so), but I have to remove the thread algae every 
third or fourth day. 

Maybe I should get another iron test kit. Most people seem to be having 
thread algae problems with much higher iron levels than mine. The iron 
level does go up when I increase the fertilizer dose, so the test kit is 
measuring something from the drops.

Michael
