poor man's dupla drops (V1 #185)


I'm very interested in your PMDDs.  I have two questions though.  First of
all, I have access to all of the ingredients except the chelated trace
element mix.  Where do you get your's from and what is the name of it? 
Secondly, my tank is quite a bit more low-tech than your's and smaller too.
 It is a 10 gal. and has no CO2 injection or laterite.  So, what type of
dosing regimine would you recommend?   Since I don't have any experience
with Dupla Drops your advice would be greatly appreciated.  Oh, and do you
think I should even try this without laterite?
