Hi friends in this article we will discuss about the best Aquarium filter suitable for your aquarium tank.
For fish keeping when we purchase aquarium the first item to be purchased is aquarium filter. Because the clarity of the water is maintained by the filter. By adding a filter in an aquarium their will a water flow inside your tank which will reduce the algae growth formation by 25 %.
Capacity of filter required. First we will have to calculate the capacity of our tank. For this you will have to measure the length, breadth and height of your tank.
Example – length of tank is 2 metre, Breadth of tank is 1.2 metre ,height of tank is 1.2 metre .So volume of tank = LXBXH = 2 x 1.2 x 1.2 = 2.88 m3.
1 cubic metre = 1000 Ltrs
So our tank capacity = 2.88 m3 x 1000 = 2880 Ltrs of water.
By doing this we can calculate the capacity of our tank.
The thumb rule for the flow rate of filter = total water capacity x 5
= 2880 ltr x 5 = 14400 ltr /hour
This means in one hour 14400 Ltrs of water will pass through this filter . That means water in our tank will get filtered 5 times in 1 hour time.
This was just an example. Based on this you can finalize your filter.
Based on the water capacity and interior of our tank we can choose aquarium filter.
Fresh water aquarium can be divided into planted aquascape and non planted aquascape.
25 ltr – 60 ltr tank
If the capacity of our tank is between 25 ltr -60 ltr , also if it is a planted aquarium we require a hang on filter only. If it is a non planted aquarium you can go for a sponge filter
60 ltr – 600 ltr tank
If the water capacity is between 60 ltr and 600 ltr we can go for canister filter.If it is a non planted tank you can go for under gravel filter.
Above 600 ltr tank
If water capacity is above 600 ltr you can go for a sump filter. For planted and non planted tanks sump filter is recommended.
Difference between each filters
The major difference between 3 types are
Hang on filter are small. Canister filters are medium sized and sump filter’s are bigger sized.
Because of the smaller size Hang on filter uses sponge as the filtration medium. In some hang on filters activated carbon also will be there. When water passes through the hang on filter the waste will be blocked inside the sponge and clear water will be passed through the tank.
To maintain the efficiency of the system and not getting blocked ,every 20 days we will have to wash the sponge filter in it.
Compared with hang on filters canister filters will have enough inner space. Other than sponge filter we can add ceramic rings also. It is better to add bacteria culture in to it . Normally the filter system will come with the full set. Cleaning of canister filter need to be done only once in 8 months.
The major difference between canister filter and sump filter is that water changing of sump filter need to be done once in 3 years.
In the case of sponge filter the cleaning of filter need to be done every 20 days and also weekly 30 % water need to be changed.
If you have added bacteria culture under UG filter(under gravel filter), you do not have to do weekly water change. Once in 6 months only required.
For small planted tanks you can go for top filters . Hang on filter is substitute for top filter and also power head of top filter consume much space compared to hang on filter ,it is better to go for hang on filter
When an aerator is connected to filter sponge it is called biological filter. This will guarantee air supply as well as filtration. This is mainly used by breeders. When small fries are formed there is chance of babies entering in to the filter and getting died. In this filter it will not happen.
