I'm sorry. I should have said "have you compared _Commercial_
fertilizers?" Very few commercial products of any kind are as
inexpensive as DIY.

Again, I was talking about _all_ of Dupla's products, (and I think
if I'm not mistaken, that the original poster was too) not just
thier fertilizer products. Also, it depends what's in your tap
water and substrate, and how you stock and feed your tank whether
you need all three or not. I use the drops and the tablets, but
have not needed the Duplagan.

Again, I have no problem with what Kevin and Paul are doing with
their trace element mix. If you are suggesting that everyone
should create their own trace element mix as opposed to _any_
commercial preparation, there may be some validity on the grounds
of cost. (though many people will still opt for convenience) That
is different than "Dupla bashing". If you're going to pick on a
particluar company, I think they are a poor choice. Their
products may be expensive, but they are well researched, and they
It seems to me that Dupla gets bashed most often because it is the
best known. There are lots of other companies out there selling
truly horrible aquarium plant "fertilizers". I am intrigued with
Kevin and Paul's ideas, and may, when I get the time to scrounge
up all the pieces, give it a try. But in the mean time, I'll
stick to products produced by the two companies I trust most in
this field, Dupla and Tropica.
