OK- heres a question for all you water chemists.  From what I have 
learned from this list the iron content for plants to grow and be healthy 
in aquariums is about .15 mg/l.  I already have tap water(well water) 
with a iron content of .07 mg/l.  Am I right in thinking that this iron 
is not chelated iron and is of no help to my plants.  If so then, should 
I adjust the iron content in my aquatic water to read .07 plus .15, 
making a total of .22 mg/l?

Also since I have never heard of a way to check for the Potassium Sulfate 
content in my aquatic water,  how do I know how much to use in my PMDD 
recipe?

Thanks for all your help and replys!
