DPH Tank of the Month
With Greg Segal
How did you get into keeping a
Planted Discus Tank?
have been keeping aquariums on and off since I was a little boy. I got my
first 5-gallon tank with corner box filter from my grandfather. A few years
later I graduated to a larger tank. Then, in my late teenage years I lost
interest in the hobby. In 1998, I became interested in the hobby again,
purchased a 35-gallon tank and filled it with community fish. At the
beginning of 2000, having become interested in Discus, I purchased a
65-gallon tank. My intention was to keep a planted Discus tank, but I
learned quickly that this would not work. So, I went with a bare bottom
Discus tank. At the same time, I converted the 35-gallon community tank to a
planted tank to learn how to keep plants. One day I decided that I was sick
of the bare bottom tank so I took the knowledge I had from the 35 gallon
planted tank and of raising Discus in a bare bottomed tank and converted the
65 gallon into a planted Discus tank. I then purchased some new wild Discus.
What do you feel has been the most rewarding
aspect of keeping such a tank?
Like any hobby, it’s the work you put in and the results you get out of
it. It’s enjoyable and relaxing to watch and fiddle with equipment, water
and layouts. It’s the ever-challenging quest of achieving the perfect layout.

What has been the hardest challenge for you in
keeping a Planted Discus tank and have you overcome it?
planting the tank and letting it sit for a while, I began to inject CO2. I
over saturated the tank with CO2 and a week later, upon putting the Discus,
Cory’s and Otto’s into the tank, the Cory’s passed on from CO2 poisoning and
the Otto’s and Discus struggled until I figured out the next morning that
the CO2 levels were way to high.
At the first water change, one of the Heckels freaked out and crashed
himself into the driftwood and ended up with a big gaping hole in his side.
I saw the entire incident with my own eyes and was not happy. He did not
make it more than a week after that.
Then, eventually the blue green algae hit so I reduced feeding. As a
result, the Discus ended up with HITH.
I did not like some plants and other plants got covered with algae, so I
had to redo the aquascape. Then, just as everything was settling down, June
of 2002 became a right-off as I was not able to service the tank, perform
water changes or feed for that entire month. The auto-feeder fed one cube of
freeze-dried Hikari bio-pur Tubifex a day for the entire month. To recover
from June, in July, I had to clean, replant, weed out the hair algae and
rescue my Discus. Four months later and the tank is finally taking shape.
Basically, my story above shows that the hardest challenge is simply
keeping everything in order and facilitating the transformation from
aquarium to aquascape. Creating a planted Discus tank is not an easy task
and it is a constant battle to keep the Discus healthy, the plants healthy
and the tank clean.
What kind of approach do you take in maintaining
your tank the High Tech way or a more natural way?
A few months ago I would have said a more natural way. But, after
recently reading a book called Ecology of a Planted Aquarium, I realized
what low-tech really means. That book advocates an extremely low-tech
natural method for keeping plants. This tank is probably somewhere mid way.
I once used a Carbo-plus CO2 device, which is extremely high tech but found
it was not working and was making my Otto’s go crazy and die. So, now I just
use standard CO2 injection. Look at my equipment list… I am probably
somewhere in between.
What piece of advice can you give to others who
are thinking about setting up a tank like this?
(1) don’t be afraid to experiment;
(2) don’t be afraid to give up on certain aspects of the tank if it means
making everything else easier; and
(3) keep a second planted tank for practice. I experimented with many
layouts and plants until I was happy. At one point I just gave up on all
stem plants. My time commitment was such, that I could not properly prune
these plants, so I gave up on them. Instead I have concentrated on broad
leaf plants such as swords, and grass like plants. In my experience these
are somewhat easier to maintain. I also recommend keeping a second planted
tank with some cheap community fish. I find this second tank great as a
plant to experiment on aquascapes and to quarantine new plants. I find that
new plants sometimes have trouble adjusting to the warm water of my discus
tanks. So, I let them sit in the community tank until they become a little
stronger and can survive planting.
