No - it is not! There is a good reason for that!
Of cause we have used all our experience and knowledge from
growing aquarium plants in 25 years, but there is a big difference
between aquarium and Tropica's submerse culture. In an aquarium
you have fish and all the space is not filled with plants!
When you feed the fish and their excrements are decomposed in
the aquarium, a lot of plants nutrients are released! Too much of
some nutrients (phosphorus and nitrate) and to little of others
(potassium, iron, manganese and other micro-nutrients).
We tested many aquariums (water analyses and dynamic factors
as water changes, quantity of fish, plants and the consumption
of fish food).
That information we combine with our knowledge about the
average optimum of nutrients for aquarium plant growth!
A computer model of the dynamic in an average aquarium was
build - and used when I with biologist made the recipe for
Tropica Master grow.

In the Tropica Master grow fertilizer we have naturally only
added what there is missing in an aquarium!
After that we have tested our recipe in 5 test aquariums at
Tropica and in a long time test among 50 aquarium owners in
many different countries!

It is no secret! We tell it in the declaration on the bottle
(K 0.79%, Mg 0.39%, S 1.01%, B 0.004%, Cu 0.006%, Fe 0.07%,
Mn 0.04%, Mo 0.002% Zn 0.002%. HEEDTA and DTPA as celators).
We have the idea: "aquarium owners have the right to know what
they put into their aquarium"!

Hello Again:
I meant to add that Tropica is now exporting its aquarium plant
fertilizer to the US. I guess you'd call it Rich Man's Dosing Drops. In
any event, it can be ordered at
http://marine-monsters.com/front/products/fresh.html. I just checked
this site out and they have a pretty good collection of Dupla supplies
too.

Tropica MasterGrow

by Dave Gomberg <gomberg/wcf.com>
Date: Thu, 01 Jul 1999

I just struggled home from the bonded warehouse with over 500 bottles of
Tropica MasterGrow (all sizes) so if you have been patiently waiting the
wait is nearly over.   They should go out Tuesday (with the SAEs).

I switched from the full Dupla treatment to TMG on 8/8/99. Other than TMG
seems to contain less K than the Duplatabs, it went fairly well. I add 75ml
TMG per week and change 50 gallons of water every two weeks in my 225 tank.

I was one of the first "converts" to TMG, well before it was available in
this country.  I was given a bottle by Claus Christensen years ago, and
have been using TMG ever since.  I was certainly not unhappy with Dupla
products, but for my plants with my tap water chemistry, TMG was just a bit
better.  (It sounds like George and Karla are finding that with their water
conditions the opposite is true)  I am basically a very lazy aquarist, and
would rather not have to does my tanks daily.  The fact that TMG uses good
chelators that easily keep my iron levels up between doses is also a plus
in my book.

As far as dosing is concerned, as you've probably read here a dozen times,
every tank is different.  I took Claus' advice when I first strated using
TMG, and began dosing at half the labelled amount, and worked up slowly
over time.  My tanks are brightly lit, CO2 injected fast growth tanks.  In
the one that has slightly less really fast growing stem plants, I dose at
just over the recommended amounts.  In the other tank with more fast
growing plants an enormous, very hungry 'Rubin' sword, and a large nutrient
sucking tiger lotus I find that I have to use close to twice the amount
suggested on the label, or the less competitive plants lose out.

TMG Daily or Weekly Dose?

I use a daily dose.  I just use a 10 ml syringe, to measure out
the right amount, and add it slowly to the tank.  I have a 
sump setup, so normally I just squirt it right into the sump tank.
But I've added it directly to the tank without trouble, just
be careful not the squirt it right at any fish!   I got a handful
of the syringes at the local pharmacy for free.  They give them
out for measuring oral dosages of liquid medicines.

I'm currently adding 6 ml per day for my HEAVILY planted 75g.  I 
started at 4 ml per day, and have increased it each week due to
visible signs of iron deficiency (mainly from my Amazon Frogbit).
At 4 ml, it was very noticeable.  After a week with 5 ml daily, it's
only barely noticeable, but still not quite right.  I'm betting 6 ml
per day will be the magic number.  The only algae is some green
spot on the glass, and some green spot algae on some of the older
Anubias leaves.
