The filter in the aquarium is the most important part of the equipment, the life support system for your fish, which removes toxic waste, chemistry, and if it works correctly, it saturates the water in the aquarium with oxygen.
For the filter to work properly, it is necessary that useful bacteria be divorced inside it, and improper care kills them, as a result creating problems with balance.
Unfortunately, most of the filters lack simple and clear instructions for the user to understand.
How often to wash the filter
All filters are different, small ones need to be washed weekly, and large ones can work without problems even for two months. The only correct way is to observe how quickly your filter becomes clogged with dirt.
In general, for the internal filter, the frequency is approximately once every two weeks, and for the external one from two weeks for very polluted aquariums, up to two months for cleaner ones.
Keep an eye on the flow of water from the filter, if it is weakened it is a signal that it is time to wash it.
Types of filtering
The easiest way in which water passes through the filter material and is cleaned from suspended matter, large particles, food residues and dead plants. Both in external and internal filters, porous sponges are usually used.
These sponges should be rinsed regularly to get rid of particles that clog them. If this is not done, the power of the water flow drops significantly and the quality of the filtration decreases. Sponges are consumable and need to be replaced periodically.
An important view if you want to keep complex fish and have a healthy, beautiful aquarium. Simplistically, you can describe it like this: fish create waste, plus food remains fall to the bottom and begin to rot. In this case, ammonia and nitrates are released into the water, which are detrimental to fish.
Since the aquarium is an isolated environment, there is a gradual accumulation and poisoning. Biological filtration helps to reduce the amount of harmful substances by decomposing them into safe components. This is done by special bacteria that independently inhabit the filter.
This type of filtration is used in emergency situations in the aquarium: poisoning, after the treatment of fish, to remove harmful substances from the water. At the same time, water passes through activated carbon, the pores of which are so small that they trap substances in themselves.
After use such coal needs to be utilized. Do not forget that you can not apply chemical filtration during the treatment of fish and it is not necessary if everything is normal in your tank.
Wash the filter correctly
Just wash the filter may not be the most successful idea, since you can destroy a colony of good bacteria in it. Therefore, it is important not to wash the filter when you make any global changes in the aquarium — a big water change, change the type of feed or frequency of feeding the fish, or launch a new fish.
At such times it is very important that the balance is stable, and the filter is a large part of the stable balance in the aquarium.
We clean the biological filter
Washcloths are most often considered as a mechanical filter that retains dirt from the water. Your fish, however, do not care what kind of crystal clear water, in nature, they live in far from ideal conditions. But for them it is important that the water be like less decomposition products, such as ammonia.
And for the decomposition of ammonia and other harmful substances, responsible bacteria that live on the surface of the washcloth in your filter. And it is very important to wash the filter so that it does not destroy most of these bacteria.
Sudden changes in temperature, pH, chlorinated water from the tap, it all kills bacteria. To wash the washcloth in the filter, use the water from the aquarium, just rinse it in this water until it is more or less clean.
Striving for sterility in this case is harmful. You can also do with solid parts – karmic or plastic balls.
Many aquarists, change washcloths in the filter too often, as advised in the instructions. The washcloth in the filter needs to be changed only if it has lost its filtering ability or has begun to lose the forum. And it happens not earlier than in a year and a half.
It is also important to change no more than half at a time. For example, in the internal filter washcloths consist of several parts and you can only change one at a time.
If only a part is replaced, then bacteria from old surfaces will quickly colonize new ones and there will be no imbalance. Taking a break in a couple of weeks you can completely replace the old content with new and not damage the aquarium.
All Fish Tank Filters contain impeller. The impeller is a cylindrical magnet with an impeller, which serves to create a flow of water, and is mounted on a metal or ceramic pin. After a time, algae, bacteria and other debris accumulate on the impeller and make it difficult to work.
It is very easy to clean the impeller – remove it from the pin, rinse it with water pressure, and wipe the pin itself with a rag. The most common mistake is when people just forget about it. And pollution significantly reduces the impeller’s lifespan and the most common cause of filter breaks is impeller contamination.
Develop your own filter maintenance schedule in the aquarium, record when you last did it, and regularly check the levels of ammonia, nitrite, and nitrate in your water.
