[sc name=”amz” asin=”B06XHSJ8MV” ]

- Supplying oxygen while filtering better with Bio-scrubber: With vibration dampening technology, the filter helps spill more oxygen to the water by agitating the surface. Meanwhile, the bio-scrubber cultivates aerobic bacteria which removes toxic ammonia and nitrite to give a better filtration.

How to choose the best filter for 10 gallon tank?
The first thing you should consider when choosing a good filter for a 10-gallon tank is its capacity display thru the flow rate. The flow rate should not be over 100 gph unless or if its maximum rate is a little over, it should be adjustable at many other lower levels.
The second thing we should consider, of course, is the efficiency of the filter media. A good filter should both mechanically keep and remove all the waste and chemically removes odors and other impurities as well as grow good bacteria for completing the nitrogen cycle in the tank.
Thirdly, the filter should be easy for cleaning and maintenance. It is best if you only have to change the filter cartridge. However, for most filters, you should also have to clear the clogged filter pads at the mechanical stage. A good filter will help you to run the tank for a long time without having to change the filter media, meanwhile, still maintain the good parameters of the tank water with undetectable ammonia and nitrite as well as ensure a long-lasting filter.
Last but not least, the filter should run quietly to help you avoid irritating noise and bring peace to your mind and soul as an aquarium should do to people.
Best filter for 10 gallon tank FAQs:
What is a nitrogen cycle?
The nitrogen cycle in the natural world is a full cycle where nitrogen goes from the air to plants to the animal to bacteria and then comes back to the air without human intervene. However, in an aquarium, the nitrogen cycle is a continuous chemical degradation of nitrogenous compounds from ammonia to nitrite and then nitrate. Final nitrates will be absorbed by aquarium plants or removed from the water by other means.
Usually, it takes 3 months for a living aquarium to finish a full nitrogen cycle: to turn all its waste into nitrate. Thus, the method of stocking a new aquarium is to gradually introduce stock and usually starting with younger, smaller fishes so that the bacteria have time to grow and keep pace with increased waste matter.
Ammonification: when fish and other animals in the aquarium expel waste or in fish food particles or plant deaths, the initial form of nitrogen is organic. Bacteria or fungi convert the organic nitrogen within the remains back into ammonium (NH4+), a highly toxic gas. This process is called ammonification.
Nitrification: in the early stage of nitrification, the bacteria like Nitrosomonas species shall help turn ammonium into nitrite (NO2_), which is very toxic to the living stock in the aquarium. The final stage of nitrification is when other bacteria like Nitrobacter help to oxidize the nitrite (NO2_) and turn it into less toxic nitrates (NO3_), which could be absorbed by living plants in the aquarium or continue to go to the last step: denitrification.
Denitrification: this is a process when bacterial species like Pseudomonas and Paracoccus under anaerobic conditions turn (NO3_) into N2 (nitrogen gas) and O2 (oxygen gas) to complete the nitrogen cycle.
How to start a nitrogen cycle?
Introducing fish to a new tank where a nitrogen cycle has not been started yet may cause fish deaths. Thus, the most important thing is to start a nitrogen cycle by introducing good bacteria to your aquarium. Fortunately, good bacteria are very available in the tank and in the air. The key is your patience because it may take several days. Adding ammonia source in the tank while constantly running the filter creates good conditions for the bacteria to flourish. The easiest way is to take one-third of tank water from a healthy aquarium on a day of water change and introduce it to your tank. Another method is to introduce two hardy starter fish such as goldfish for cold water tanks or zebra danios for warm freshwater tanks. Do not hurry in introducing more fish because they will produce more ammonia than the bacteria in the tank could handle and result in fatal fishes.
