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
Thanks for all your help and replys!
