1. They reduce pathogens, etc.
2. It reduces the source of odor and turbidity.
Basically, the source of pathogens and odor is leftover food and waste products such as feces. However, it is difficult for humans to reduce pathogens directly even if we want to. Therefore, we have to be careful to reduce the number of pathogens,The role of the filter is to keep good bacteria in the filter to help defeat pathogens and other bad bacteria.It is.
There are many types of filters, and each one has its own characteristics. In this issue, we would like to explain four of them.
1. Upper type filter
2. External filter
3. Throw-in (underwater) filter
4. Sponge-type filter
An upper filter is a filtration device installed on top of the aquarium tank. How it works,A system that uses a pump to pump water from the tank, filter it, and return the water to the tank.It is. It is often not possible to install it in aquariums without rims, which are becoming more common these days. Therefore, we recommend that you choose an aquarium with a rim when using an upper filter.
Available at low cost.
No need to think about where to install it.
Easy to care for
...Not very good looking.
Noise from motors, etc. is too loud.
...very small places for lights, etc.
Those who do not have time to take care of it.
Since the lid can be opened to see the filtering material inside, those who do not have time can open the lid daily to recognize the replacement of filtering material as soon as possible.
Mainly keepers of goldfish and large fish
Goldfish, for example, eat a great deal of food, which can easily contaminate the water, so a top filter with high filtration capacity is a good match. It is also recommended because it is easy to care for, so if the filter gets dirty, you can notice and take care of it right away.
・ Those who keep them in a quiet place or for relaxing.
Since the water is pumped and filtered, the motor attached to the pump is very noisy, so it is not suitable for places where quietness is preferred, such as bedrooms and guest rooms.
Those who care about looking good.
Unlike other filters, it is difficult to hide them, so they are more visible to the eye.
This filter is used by hooking it to the top edge of the aquarium.Many are small, making them easy to install, remove, and maintain.It is. Also, many products have low motor noise, so there is less stress caused by motor noise, etc., as in the case of upper filters. However,Compared to an external filter, the filtration capacity is lower because there is less space for filter media.Also, if there is a height difference between the water surface and the sump pump, the water may make a tapping sound on the water surface, which can cause a pitter-pattering sound in the summer or when there is a lot of water evaporation.
Available at low cost.
Few places to install.
・The top of the tank is not used, so it can be used for lights and other locations.
Quiet motors, etc.
Low filtration capacity
Difficult to adjust water volume
Waterweeds and other plants often get caught in motors and other equipment.
Those who do not have much space for installation
It is very good for people who only have room for an aquarium tank, for example, because it is attached to the edge of the tank.
Those who care about looking good.
Even if you put a back screen on the aquarium tank to make it look better, it is useless if the filter stands out.
Those who do not want to do much maintenance
By opening the top lid, you can see at a glance whether the filter media needs to be replaced, so you know immediately when it is time to perform maintenance. Maintenance is very easy, as the only thing that needs to be done is to replace the filter media.
For those who want to put a large number of living creatures in the house.
You should be aware that the filtration capacity is not good, and if you put in a large number of living creatures, the filtration capacity may be exceeded. If you only have room for an external filter, we recommend that you buy a filter that is larger than the appropriate filter.
A throw-in filter is a type of filter that is used by placing the filter inside the aquarium. Therefore,Also known as "underwater filters.There are two types of air pumps: one uses air bubbles connected with tubes to create a water flow, and the other uses a submersible pump to create a water flow. The most famous air pumps are the "Suisaku Eight" and "Roca Boy. For the submersible pump method, "Eheim Submersible Filter" is well-known. In fact, the air pump type is the easiest to obtain.Throw-in filters can be used as stand-alone filters or as sub-filters for large aquariums, and are popular with people who want to use filters for the first time.
Available at low cost.
Easy to install
No need to think about installation location
Low filtration capacity
A separate blower is required.
Noisy air.
Those who want to keep the price as low as possible.
The price is lower than other filtration systems, so it is good for beginners and those who want to add it as a sub-filter.
Those who use smaller tanks
The filtration capacity is not very good, so it is good for those who keep it in a small tank or plan to keep it without too many creatures.
Those who keep it for a quiet place or relaxing.
The air noise is surprisingly loud, so you should consider this if you are placing the aquarium in a bedroom or other place where quiet is preferred.
Those who use large aquariums
The filtration capacity is not very good, so it is not suitable for handling a lot of dirt. If you are putting it in a large aquarium, it is better to use it as a sub-filter.
This is a type of filter that is attached to an air pump.It allows bacteria to grow inside the sponge to create "biological filtration". It can be used as a stand-alone filter, but its filtration capacity is lower than those of external or upper filters.So it is generally used as a sub-filter to make the main filter maintenance a little easier.Cleaning may seem a bit tedious because the sponge-type filter itself can become clogged with dust and other debris.
Available at low cost.
Easy to install
Multiple installations are possible, even for large aquariums.
Maintenance is required due to easy clogging by debris, etc.
A separate blower is required.
Noisy air.
Not very good looking.
Those who do not keep large fish, etc.
If the fish are placed in a large fish tank, feces and other debris will clog the sponges, preventing them from producing their full potential,
Looking for a sub-filter?
Sub-filters are great because they reduce the load on the main filter, making it easier to replace and maintain the filter media.
Beginners
The sponge type is difficult for beginners to handle because the number of sponges and the size of the sponges vary depending on the conditions and location where they are put in very much.
Looking for a main filter?
As a main filter, it is too faint-hearted and its filtration capacity is insecure, so it is better to use it as a sub-filter.
