Hi.  I have ound a place that will sell me 100g of a Chelate trace element
mix for $6.00!!!  The contents of the mix is (7% Fe, 1.3% B, 2% Mn, 0.4% Zn,
0.1% Cu).  Is this the stuff i want to use to make PMDD ???  If so once i
make the 300ml solution up how much would i use in a 55 gal tank???  Also,
would 100g of that mix last a while???

Thank you for the help,
