how to do water change on saltwater aquarium

As with people fish thrive when kept in an environment as close to their own as possible.

For this reason aquariums should be carefully structured to imitate
the natural environments of the species it is home to as closely as possible.

Even if it is not possible to duplicate exactly the living conditions
found in the deep blue the fish will benefit from the effort.

Fish are also very adaptable creatures. It is what allows them to live
and thrive in captivity when many other marine animals are unable to make the change.

The fish will adapt to the environment around them and learn to live in the conditions of their tank.

It is important that these conditions remain as constant as possible. As in nature a tip in the balance of the elements in an aquarium can bring with it devastating consequences.

It is important that changes in the aquarium environment be few and far between.

This is generally a very simple matter until the time comes for the water in the tank to be changed.

In nature the water in the ocean is constantly cycling; therefore,
the water never has the opportunity to become stale and
overloaded with elements that will have a negative impact on the
well being of your aquatic friends.

Since this is not the case in an aquarium even with an excellent
artificial filtering system and organic filtering methods combined it
will still be necessary on occasion to manually clean the tank.

The water with which you replace the dirty water in the aquarium
should be as close as possible to the water that was originally filling the tank.

What this means is that if you opted to buy a pre-made saltwater
mix when you started your tank you should continue to use that same pre-made saltwater mix.

If you made your own saltwater you should use the same type of
sea salt in the same proportions that you used in the beginning.

If you opted to transplant ocean water or purchased filtered ocean
water you are going to want to use that same type of water when you make the change.

Water in aquariums should be changed every couple of months,
more if you happen to notice that wastes are beginning to build up.

This will be evident by the hazy look the previously clear water will
take on and the obvious accumulation of waste at the bottom of the tank.

Be sure when you change the water you also clean the components of the tank and the inside of the glass itself.

Putting clean water into an empty tank is along the same lines as
putting clean clothes on a dirty body-there is little point.

By keeping your tank clean and the conditions as constant as
possible you are giving your fish the best possible chance to thrive
in their artificial environment, guaranteeing that you will be able to
enjoy their beauty for a very long time.

Types of filtration
Filtration is needed to rid the tank of toxic wastes, undesirable
particles, and other dissolved chemicals.

There are many different designs of filters, and their mode of
action may be biological, mechanical, or chemical, or a combination of these.

Biological filters remove nitrite and ammonia from the water

FILTRATION CHOICES
Two or more filters are often used in the same tank to maximize
water quality and cut ammonia and nitrite, which reef fish cannot tolerate.

Biological filters, such as undergravel and trickle designs (right), are
often teamed with external power filters, which pump water
through an external canister containing filter media such as sponge,
filter wool, or activated carbon.

The filtered water is then sprayed back into the tank through the
fine holes of a spray bar—a process that helps oxygenate the water.

Some aquariums feature ozonizers— units that produce bubbles of
ozone gas to oxidize waste matter—or protein skimmers (below),
which use yet another method to remove potentially harmful organic waste.

A protein skimmer or foam fractionator is a device used to remove
organic compounds such as municipal water treatment facilities and public aquariums.

Smaller protein skimmers are also used for filtration of home saltwater aquariums

The protein skimmer works in a different way from conventional filters.

A stream of electrically charged air bubbles rises through a plastic
tube; proteins and other organic wastes stick to the bubbles and
rise to the surface, where they form a thick foam.

This must be regularly collected for disposal, preferably twice a week.

undergravel filter for saltwater aquarium

In an undergravel filter, a colony of beneficial bacteria establishes
itself in the substrate.

As water is drawn down through the filter bed, the bacteria break down organic waste produced by the fish.

The trickle filter provides sophisticated biological and mechanical filtration.

Water is drawn up from the tank and sprayed over a stack of
different filter media, through which it trickles before flowing back into the aquarium.

Spraying also oxygenates the water, improving bacterial action within the filter.

for bacteria that convert these natural waste products into harmless compounds.

Mechanical filters remove particles by forcing water through some kind of filter cartridge.

Some of these cartridges contain filter media that trap particles as
small as 3 microns across and can be used periodically to scrub the water of bacteria and algal blooms.

Chemical filters remove dissolved substances from the water, such
as ozone, chlorine, heavy metals, and medications.

Most work by forcing the water through a filter medium of
activated carbon (a manufactured form of bcarbon that is highly porous).

Chemical filters are useful for eliminating the yellow coloring
that often develops in aquarium water.

WATER STERILIZATION

Ultraviolet (UV) light is a powerful sterilizing agent, capable of
killing bacteria, parasites, and even tough algal spores.

Some aquarists use sterilizing units that pass water from the filter
over a UV lamp before returning it to the tank.

There is some evidence that use of these lamps reduces the incidence of disease.

CHANGING THE WATER

Partial water changes not only reduce harmful accumulations of
nitrate, phosphate, and other chemicals by dilution, but also
replenish levels of carbonate (reinforcing the buffering capacity)
and trace elements, which are vital to the well-being of the tank occupants.

When setting up the aquarium, make an inconspicuous mark on
the side of the tank with a felt-tip pen to show the water level
when the tank is full.

This makes it easier to fill up the tank with the correct amount
of water, both when making partial water changes and when replacing evaporated water.

check the salinity

1.)Check the salinity and temperature A conductivity meter gives readings in millisiemens per centimeter (mS/cm).

At 77°F (25°C), 50.1 mS/cm corresponds to an SG reading on a hydrometer of 1.023.

2.)Drain the water and clean the gravel Fix a gravel cleaner to the siphon and suck up mulm from the substrate while draining the water.

This will prevent the undergravel filter from becoming clogged with waste.

add more water

3.) Add more water Replace the drained water with a fresh, dechlorinated salt solution of the correct temperature and salinity.

Test the water for toxic copper before adding it to the tank.

4.)Clean out the protein skimmer Carefully remove the accumulated debris from the cup.

Then rinse the cup with warm, dechlorinated water to remove fat deposits, which make the skimmer less efficient.

 

CHECKING SALINITY
The correct salinity, in terms of specific gravity (SG), will be in the
range of SG 1.020–1.025, depending on the speciesin your tank.

Salinity can be tested with a hydrometer or a conductivity meter,
which determines the water’s salt content from its ability to conduct electricity.

With a hydrometer, you may need to adjust the reading to take
account of the water temperature: cold water is denser than warm
water, so it gives a slightly lower SG reading.

The instructions provided with the hydrometer should
enable you to make the right adjustments.

TESTING THE WATER

test kit

Tank samples can be tested with reagents to monitor a range of
water parameters, including pH and levels of chemicals such as
iron, nitrate, phosphate, carbonate, calcium, strontium, iodine, and copper.

Read the instructions on the kits carefully, store them
appropriately, and use them before they are out of date; otherwise,
they will give inaccurate readings that may endanger the health of
both fish and invertebrates.

Electronic meters give more accurate results for many of these
parameters, but they are far more expensive.

Test kits use reagents that cause the water sample to change color. The sample is then compared to a color chart that gives the numerical figure.

I am a koi fish keeper and breeder a husband of beautiful wife Maybel and beautiful daughter May Carl I have been in fish keeping hobby for over 35 years. Like many kids in the 80's We catch fish in the rivers and canals and kept it in the "pasong" local visayan name for pond. or a large mayo bottle since We don't have aquariums yet on that time. decades later their is a small petshop open in my place and that starts me from buying aquarium and fishes that are sold in the pet store decades later start growing goldfish and koi fish until today.
