     I have used all three (Dupla, Thiel and Aq Pharmaceuticals) products 
     over the last 2 years. 
     Let me definitely say -- my plants didn't really grow until I used 
     laterite in some form. So be sure to use it!!
     I agree Dupla is very $$$. I have been pleased with Thiel laterite, 
     and I think I have come up with a way to get laterite powder into an 
     established aquarium (see my other post).
     I would be interested to hear from other members : Thiel recommends 1 
     lb per 125 gal. It seems that when I "replenish" my aquarium with the 
     recommended amount the following happens:
     ))plants start growing great in about 3-4 weeks after adding 
     additional laterite
     ))this lasts about 3 months (I am usually able to measure some iron 
     for about 2-4 weeks after new laterite)
     ))the laterite seems to "poop out" in 3-4 months (I can't measure iron 
     at this time, and use an iron supplement). plants no longer have a 
     "healthy glow" about them
     I just tried 1 lb. per 55 gal tank last week (3 months after 1/2 lb of 
     granules / powder). I looking forward to see how this works. NOTE: I 
     do NOT use an undergravel filter, and this may have something to do 
     with it.
