Gravel
Don't use too coarse a gravel. Many choices are
available and we can help in pointing out the best choices for optimum plant
growth. Depth of gravel should be a minimum of three and preferably four
inches. Color is irrelevant.
Lighting
Maintain adequate lighting. Recent research
indicates that the intensity of the light is even more critical than the
duration. A typical color enhance bulb, such as a gro-lux, may be adequate
for a ten gallon (or other 12 inch high aquarium) but taller tanks need a
higher degree of luminance. Some modern reflectors or hoods have the
capacity to hold two bulbs. If this is the choice you make, we strongly
suggest that two entirely different type of bulbs be used. One choice would
be an enhance bulb in front so that your fish show to their best advantage,
and a bulb more advantageous to plant growth in the rear.
Fertilizer
Remember to use fertilizer. The old adage that fish droppings will fertilize
the plants is partially true. Modern filtering techniques are often
rendering the aquarium too sterile! Most liquid fertilizers, in addition to
replacing needed trace elements and minerals, actually aid in changing mulm
(a pretty word for fish droppings) into substances that are more easily
absorbed by the plant's roots. A good quality liquid fertilizer (shake
thoroughly before using) may be adequate for a beginner's aquarium or even
one of small dimensions. However, those wanting optimum results, especially
for swordplants, anubias varieties, cryptocorynes, and any plants that send
runners to reproduce, would be wise to also purchase one of the many
products available that apply fertilizer directly to the gravel.
Planting
When planting rooted plants, it's critical that they not be placed too
deeply in the gravel. We have found this to be the most common cause of
swordplant mortality. When planting, hold a rooted plant between your thumb,
index and middle fingers. Gently drill a hole with the foremost finger, and
remove after reaching a selected depth. Then, and this is critical, pull up
on the entire plant very gently until you can actually see the top of the
root structure. This is less critical among cryptocorynes than among
swordplants, and is an absolute necessity with pygmy chain swordplants.
Pruning
Prune your plants periodically. It's generally
advisable to place some plants toward the rear of the tank in order to hide
heaters, siphons and the like. Next, rocks or driftwood will hide the less
attractive lower plant sections as well as offer both a contrast and feeling
of depth. Then, place mid range plants with another level of rocks or other
decorations. Lastly, small foreground plants in the very front complete the
descending motif and further hide the bottoms of the plants immediately to
their rear. Most of this is common sense, but this initial plan can
eventually go astray if some pruning isn't done as the plants mature. When
selecting plants for tank placement, pay attention to how rapidly they grow
and what height they will eventually achieve. In general, bunch plants grow
rapidly while rooted plants grow much more slowly.
Filters
Avoid an undergravel filter if at all possible. There are instances when
we've heard of successful plant growth while using an undergravel filter,
particularly one of slow water turnover. But in general, it's a no no. If
you must have one, or if you already have one and don't want to remove it,
consider leaning heavily on potted plants.
Medications
Be careful of medications. Some medications that are not directly harmful to
fish can be lethal to plants. Dyes such as malachite green and methelene
blue should not be used. In addition, many antibiotics can be equally
dangerous. There are medications available that are less harmful. Carefully
reading labels is always a necessity before introducing any foreign
substance that can affect the balance of an aquarium's system and should be
followed for plants as well as fish.
Terrestrial Plants
A word about terrestrial plants in the aquarium.
In Nature most aquatic plants grow above as well as below the water's
surface. Many reproduce through flowering and pollination that occurs in the
atmosphere. Some of the plants you buy in your pet store were grown above
the water for various reasons. They should adapt, grow and develop a softer,
and usually more attractive submerse leaf structure. Other plants that are
often available are not aquatic at all. These plants cannot grow or
propagate underwater. A few will exist for months, but the majority will
have a life span of only a few weeks when submerged. These should be viewed
as accent plants (for they are usually quite attractive) and pose no danger
when added for their ephemeral beauty.
