2. INTRODUCTION
All the aquatic life in an aquarium is it’s software whereas all
the accessories is it’s hardware parts.
Which are used to maintain the water quality and all the
aquatic life in an aquarium.
Various accessories are installed in an aquarium as hardware
such as Filters, Heaters, Lights, Pump, Air stone, Plants, Toys
etc.
Accessories could be further classified as essential and
decorative.

3. DIFFERENT ACESSORIES
 Filters
 Heaters
 Aerators
 Aquarium gravels
 Aquarium plants
 Air line accessories
 Hand net
 Scraper
 Worm feeder
 Silicon gun
 Toys, etc.

4. FILTERS
Filters play an essential role in performing
mechanical, biological and chemical functions in
aquarium.
Promote the nitrogen cycle by providing a medium
for bacteria growth.
Remove debris and waste from the water.
Aerate the aquarium water by producing water flow
and bubbles.

5. Filters are of three types:-
 Mechanical filter
 Chemical filter and
 Biological filter
Biological filter are again broadly divided into 3
types:-
a) UG filter b) Foam filter c) Power filter

6. 1. Mechanical filtration
During mechanical filtration, solids are trapped by
filter.
The common filter media used are filter floss, plastic
foam and gravel /sand.
Popular mechanical filter are-
Canister filter
Power head filter
Air lift box filter

7. 2. Chemical filtration
 In this process the used media can alter the chemical
composition of the water. Chemical media also trap
solids mechanically.
 For example-
 The alteration of pH using lime rich material,
 Reduction of hardness by ion exchange resins,
Toxic gases absorbed by activated zeolite and
activated charcoal.

8. 3. Biological filtration
Biological filtration involves enhancing natural
populations of the bacteria which operate the nitrogen
cycle.
Biological filtration takes place in any mechanical or
chemical filtration system.

13. HEATERS
Tropical fishes and plants in a temperate climate
inevitably involve artificially heating in water in the
aquarium.
Heating is most commonly done by using immersion
heaters with adjustable thermostat.
The power of a heater is selected on the basic rule of
heating having
 10 watts per 5 liters of water for tanks of 120 cm length,
 6 watts per 4.5 liters of water for tanks of 60 cm length.

14. Heater-thermostat

15. AERATORS
Oxygen requirement of an aquarium is closely related
with water temperature and increased temperature
results in increased metabolic rate and hence oxygen
requirement.
Aeration serve to circulate oxygen around the
aquarium and also required for the running of
filtration systems, toys, etc.

16. The aerator forces a
stream of air bubbles into
the water
Aerator accessories

17. Lighting arrangement
Proper illumination is important for healthy functioning of an
aquarium.
Providing visual display of ornamental fishes to their best
affect.
 It also stimulates growth of the fishes and plants.
As a thumb rule, 40 watts of tungsten light or 10 watts of
fluorescent tube work ideally for every square foot of water
surface.
Lighting for 10 to 15 hours a day is considered enough.

18. Florescent & Tungsten Tubs

19. gravels
It can act as a substrate for the growth of live
aquarium plants,
It can also be used as a filter media for biological
filter,
It will enhance the beauty of aquarium

20. Plasticplants
Plastic plants have advantage over the natural plants
as fish can not eat them,
These plants are more durable and do not need
regular illumination.
