The aquarium
lights should be left on for 10-12 hours each day to encourage healthy
plant growth. The plants in the aquarium grow at different rates and
you may find it necessary to prune the faster growing species. Removing
the top 2-3 inches of plants with stems is an excellent way of propagating
these species, as well as encouraging the original plant to produce
lateral shoots, giving it a more bushy appearance. This can be done
at any time, but is considerably easier when the water level is reduced
during a partial water change. This is also an ideal opportunity to
remove any dead leaves from the plants. They not only look unsightly,
but also decompose and adversely affect the water quality.
Sufficient light is essential for good
plant growth. As a rough guide you should allow 15-20 watts of light
for 900 cm5 of aquarium length. A reflective surface above the light
will ensure that you aquarium receives the maximum benefit from the
lighting, with little waste. So that this light reaches the plants it
is important to keep the condensation tray as clean as possible.
Any dirt or
algae on the tray may absorb certain wavelengths of light and adversely
affect plant growth. On a more occasional basis it is necessary to change
the fluorescent tubes (say every 6-12 months) because their light output
decreases rapidly with age.
If plants are not being kept in the aquarium the light
will only be needed for viewing and so can be less intense. It can also
be left on for a shorter period each day.
Remember aquatic plants will benefit from the addition
of an aquarium fertiliser such as Tetra FloraPride at each water change.
Your filter will also need cleaning to remove any debris
that it may have trapped.
We have already mentioned how undergravel filters should be cleaned. The
filter media in box
or foam filters should be removed and rinsed in old aquarium
water. Do not use tapwater as the chlorine present will kill many of the
beneficial bacteria so reducing the effectiveness of the filter. Your
aim when cleaning the media is to remove excess debris without removing
the helpful bacteria, therefore a quick clean is adequate.
When replacing the water it is important to ensure that
it is the same temperature and quality as the water in the aquarium. Any
large changes could stress the fish making them more susceptible to
infection by disease. The replacement water should always be treated
with Tetra AquaSafe in order to remove any potentially dangerous
chlorine and metal ions.
There are also a number of water treatments which can be
added at each water change to reproduce the conditions found in the fish’s
natural environment. Regular use of these products encourages fish to
develop their full colouration, improves resistance to disease and
induces spawning. Tetra Blackwater Extract is a unique blend of peat
extract, naturally occurring vitamins and plant hormones, which
recreates the natural water conditions found in areas such as the
Amazon. Used in conjunction with Tetra AquaSafe,
it is very useful in acclimatising new fish to your local water
conditions.
Tetra Cichlid Vital contains the iodine and vitamins
lacking in tapwater. Routine use of Cichlid Vital will greatly improve
the overall condition of your fish, this being most noticeable in the
many species of cichlids, where an improvement will be noticeable within
1 week. The beneficial effects are not limited to cichlids however and
similar changes can be seen with any freshwater fish suffering from a
vitamin or iodine deficiency.
When replacing the aquarium water again use a siphon.
Direct the water flow along the length of the aquarium rather than at
the plants or gravel. In this way you avoid disturbing any debris in the
gravel or uprooting any plants
