Start Your Aquarium Right
Watching a tranquil aquarium, listening to the trickle of water and
visually drinking the color reflections of exotic fish is a busy man's dream.
Cleaning, fixing, treating, and generally slaving to keep an aquarium
beautiful is a nightmare.
The secret to maintenance-free aquariums is in developing a healthy,
balanced ecosystem that virtually takes care of itself.
Aquariums, need a little help to get started.
Unlike ponds, it is harder to develop the care-free ecosystem
in a small volume of water than in a large one. But that doesn't
mean that it is really difficult.
Begin by understanding the cycling process.
(See the nitrogen cycle image above)
Filling the aquarium with water (or even topping it off as it evaporates)
introduces dangerous chemicals into the water. Chlorine and Chloramine
are toxic to fish and not healthful for plant growth. Some water even
contains heavy metals. Always treat new water with toxin-neutralizing
Saltwater or marine fish and invertebrates
are far more sensitive to water impurities and changes in water
conditions. While most tropical tanks do
very well with treated tap water,
it is a good idea to use de-ionized water or water
filtered by reverse osmisis techniques for
marine tanks. However, reverse-osmisis water is so pure that it is depleted
of essential trace elements and minerals
which must be added back to the tank.
Now that you have clean, toxin-free water, you need to start some
beneficial bacteria growing in the aquarium and in the filter. Aerobic
(oxygen loving) bacteria
literally eat and digest organic waste products, turning them into
nitrates and fertilizers for plants.
(1) There will be plenty of waste to de-toxify. Fish eliminate
in the water and plant material and excess fish food fall to the bottom
and decompose. If not properly turned into beneficial products,
your aquarium will putrify and die.
(2) Several products contain beneficial (aerobic) bacteria with which to
seed the aquarium as well as enzymes to speed the decomposition
process. (enzyme and sludge-removing products will be used
regularly to enhance the natural cleaning of your aquarium)
Bacteria cling to gravel, rocks, fixtures and to your filter media.
They need a large surface area over which the water (carrying its pollutants)
can pass. Your filter contains a pre-filter pad that traps large
particulates and debris (which you should clean frequently).
The filter also contains other materials on which the bacteria grow.
Do NOT clean this portion of the filter unless absolutely necessary,
and never clean it with chlorinated water.
That kills the bacteria you have worked so hard to establish.
Now that you have introduced bacteria, you must give the
bacteria something to eat so that they can "live long and prosper".
Begin to add small fish and plants.
Many new tanks suffer
from "new tank syndrome" - cloudy water.
The water becomes cloudy a day or two after
start-up because of the death of already-present bacteria.
The particulates and bacteria that make your water
cloudy can be removed by adding water clarifiers
that "clump" the cloudy molecules together and allow them to
sink to the bottom or get trapped in the pre-filter.
Beneficial bacteria feed on the decomposing
molecules of cloudy water and turn them into beneficial products.
During the first few weeks, before the bacteria has
become settled and multiplied, you'll need to test your aquarium's
water quality frequently. Too much organic decay and too little bacteria
can lead to a high ammonia level which is very toxic to fish.
A good all-around water test kit
for aquariums will be needed.
(do not use a swimming pool or hot tub kit)
(2) "Ammonia Burn" damages fish gills and scales.
Stress coats may be added to the water during the "cycling" process
(or any time you suspect high ammonia or stress)
to help prevent damage
to the fish from ammonia build-up. They are
a good maintenance treatment any time you are adding water or otherwise
adjusting your pond's water quality.
Adjusting the pH of the water is also important. Most
tropical aquarium fish thrive in neutral to soft water - water whose pH is at 7. Your
test kit will allow you to see the pH. Afraican Cichlids or Marine fish
generally like a pH in the 8.3 range.
Several products are available
for adjusting the pH of the water.
Fish also need electrolytes - especially when they are under
stress as when being introduced into a new aquarium.
Adding aquarium Salt will give them a boost.
(If you have water plants, you may skip the salt as some plants do not
do well in salted water.)
(3) If the water begins to turn green, algae may be blooming
in your new ecosystem: too much sunlight hitting the tank (even
indirectly) or light bulbs
with too much UV light, too much fertilizer (from the nitrite
turning to nitrate), too few plants.
Adjust these factors by doing frequent small water changes, adding more
live plants, and consider adding a UV filter to the system.
There are also algae-treating additivies
which will help in the short run.
(4) As your aquarium settles further into its cycle,
it will become more and more stable and care-free.
The most important maintenance procedure
that should be preformed routinely is small water changes
which include gravel vacuuming (to suck
any debris or sludge from the gravel), and
cleaning the pre-filter.
to speed the decomposition, and do water changes of
approximaely 25% of the tank water each month.
