Maintenance is essential to the success of your aquarium.
Regular water changes of 20-80% are required along with filter
and tank maintenance. The more you learn about your new hobby
the more you will realize that no one knows all there is to
know. Experiment, read, discuss and share your findings with
others and you will truly know the full enjoyment of home
aquarium and mini reef keeping for years to come. In this
section we will teach you how to maintain your aquarium and
enjoy being a proud owner of the beautiful aquarium and beautiful
The glass of the fish tank becomes dirty and you must clean
it every time you changing water in the tank. If you practice
cleaning glass regularly then you will not face any trouble
cleaning it but if you are lazy in keeping the glass clean
then after a long period of time the sheath, which accumulates
above the glass, becomes stubborn and might cause trouble
At one time or another all aquarium hobbyists have the need
to clean the glass. For external cleaning, I recommend only
using ammonia based cleaners when absolutely nothing else
will work. I use one squirt on a rag to clean all of my tanks.
After using the rag, try using newspapers to dry the glass
and remove any ammonia residue. For internal cleaning there
are several very good commercial products available at any
Water transformation is the backbone to your maintenance schedule.
Depending on the biological load on your filtration system
(living things in your tank and the waste from feeding them,
along with natural decay of plants), the amount of water you
need to change regularly will vary greatly. The best way to
determine how much water to change is by testing the water
before and then about one hour after the change. The reason
for waiting is to allow the water to completely cycle through
the filter beds. If your tank is new, you may want to continue
testing every 24 hours until it is under control.
If you do not yet have test kits for your water, you should.
Test kits are the only way to really know what your water
is all about. Most local aquarium stores will test your water
for you without a charge. This is nice, but not convenient.
Buy test kits appropriate to your tank. For marine tanks you
will need a specific gravity meter that measures salinity
Prior to changing the water you should perform several steps.
First, test the water with your test kits so you will know
if you need to change a little or a lot. Next, make any internal
changes to the rock and substrate. Next, if needed, clean
the inside of the tank glass (see glass cleaning above). Finally,
prepare your water by mixing in the right amount of salt to
Now, you can begin to remove the water that will be replaced.
For tanks with under-gravel filters, the best method is to
use a vacuum tube. To do this, use a long piece of tubing
and submerge it until full of water. Put your thumb over the
end you will be taking out of the tank to keep the water in
then place it in whatever container you will use to do away
with the old water and let your thumb off. If the tube is
lower than the tank, gravity will take over and start a siphon
effect drawing the water out. Some of the gravel may come
part of the way up the tube but will probably not come out.
For larger tanks you may want to setup a pump system that
systematically removes and replaces small amounts until the
new water is exhausted. In either case, remember to add the
new water very slowly. Do not add more than twenty percent
of the total of the tank capacity in less than one hour. After
about one hour the tank should have cycled the total water
contents through the filter system and now is a good time
to take your second round of test to determine the results
of your labour.
