So the PMDD doses recommended vary from 2 to 40 drops per day for a 54 l
tank?
All I can say is that 4drops/day has not yet allowed measurable iron or
nitrate in the tank.
I'll experiment.

You might find that adding this will not supply the things you need
for good plant growth if you have CO2 injection.
This was based on the premise that PO4 and Fe at non limiting
levels(for plants) will cause algae.

This is not true.

This was also devised for low light tanks, 1.5-2w/gal of normal output
FL's lights.

It also suggest low CO2, 10-15ppm or so, 20-30ppm is better.
Many folks need to add PO4 to have good growth, unless your tap water
has 1.0ppm or more and you do 50% weekly changes, you'll need to add
it as well.
