Ironite
For some time now, I have been using Ironite to feed my aquarium plants.
It is inexpensive, readily available and appears to have all of the
necessary goodies in it. The analysis follows:
N ............... 2.0%
Ca .............. 1.0%
Mg .............. 1.0%
S ...............12.0%
Co .............. 0.0005%
Fe ..............11.0%
Mn .............. 0.05%
Mo .............. 0.0005%
Zn .............. 0.5%
Nitrogen is derived from Urea. Fe & S are derived from pyrite and
from Iron sulfate. The rest of the elements are derived from sulfates.
When added to the tank, the water clouds for a short while, then clears.
The plants appear to love it. Various species of Echinodorus ('Red
Rubin', 'Ruffled Swd', E. quadricostatus) and a selection of Aponogetons
(A. feestralis, A. longiplumulosa, A. crispus, etc.), etc.,etc., etc.,
all do very well, indeed. From time to time, I supplement their diet
with an appropriately sized fragment of a Gro-Power tablet inserted under
the roots. I have never weighed what I put into the tank, I just add
what feels good at the time. Nothing scientific. I have very little
algae, although there is some of that damnable tough, dark green stuff
forming on the lace leaf plant. I don't really have a question, just a
blurb to see what others have to say. I do have a very crude yeast CO2
generator that I conjured upp a few weeks ago ( I do have a CO2 bottle
but no regulator), and the lighting is limited to a 48" Triton and a 48"
Day-Cycle bulb (for reptiles). Unfortunately, this bulb is not included
on the list that came out of the Krib recently.
