RE: fertilizers

Daniel Boyer asks about using terresterial fertilizers in aquariums...

No need to list the contents again - this stuff is designed for evergreens
and azaleas, and other "acid loving" plants. It was NOT designed for
aquariums. Way too much Copper, for one thing...

>(It is labled as a "soil acidifier" BTW.)

What would make you think that you need a "soil acidifier" in your
aquarium's substrate?

>Total Nitrogen (N)......30.0%


Oh my God! My guess is that if I was growing alfalfa, this stuff might be
great, but an aquarium fertilizer should not have 30% Nitrogen. You do have
fish in your tank, don't you?

If you are looking for fertilizers for your aquarium, I'd recommend that you
try one or more of the following:

Duplaplant / Duplaplant 24 from Dupla
Flourish / Flourish Iron / Flourish Potassium from Seachem
Floreal / Ferreal from Aqualine Buschke
Tropica Mastergrow from Tropica
PMDD - mix your own (chemicals available from Homegrown Hydroponics)

Your aquarium is NOT a vegetable garden, nor is it a perennial border.
Products designed for  aquariums are NOT outrageously priced all of the time
and they will work better in aquatic environments than those designed for
use on land.
