              How To Choose The Best Filter Cartridge For Fish Tank?

              How to change the old filter in the tank

              Leaving the old filter cartridge for fish tank

              Keeping the old filter or cartridge in the tank with the new filter for four to six weeks is the most effective and easiest way to prevent the loss of bacteria. Everything you need to do is just install the new one and remove the old one after a month or so. Through this method, it will give the new filter enough time to accumulate beneficial bacteria from the old environment to maintain the balance in the aquarium. However, you need to keep a close eye on the flow rate. Fast currents increase the stress level of the fish as they are constantly swimming against the current.

              A slow flow rate is important not only for fish but also for living plants, as it aids in maintaining healthy levels of carbon dioxide.

              Filter pads can be used to reduce the flow rate if required.

              Reuse old filter media

              The way this is what you have to do is remove the media from the old filter and put it in the new filter. The majority of beneficial bacteria are stored in the media itself, saving the majority of bacteria. However, you need to choose new and old filters that must be the same shape and size as the cartridge. Always make sure the old cartridge is in good condition before you put it in the new filter. Damaged or broken cartridges should not be reused. Keep the old cartridge in the new filter for four to six weeks before replacing it with a new one. This is the time when enough bacteria build up on the new filter, making it safe to switch to new media without causing any serious bacteria loss.

              New filter colonization

              When taking out the old filter, remember to take out its cartridge. Check if it is in good condition and just put it inside the aquarium with the new filter. In particular, the media does not fall out, it will work the same way as inserting the old cartridge into the new filter.

              Over a period of one month, the new filter becomes a breeding ground for bacteria from the old cartridge.

              You can still run two filters simultaneously in a permanent aquarium or keep reusing the old cartridge inside the new one until it starts to fail, this method should only be used for a month.

              Understanding biofiltration and preventing the loss of beneficial bacteria

              Most aquarists do not know about the important role bacteria play in the aquarium. As a result, many people quickly and eagerly upgrade the filter in their tank to the point of eliminating most of the beneficial bacteria without realizing the impact it can have.

              Biological filtration is a method to help clean the water in an aquarium by using microorganisms to keep the aquarium healthy.

              Often beneficial bacteria build up gradually on the filter and cartridge responsible for operating the main waste treatment system in the tank.

              All waste from uneaten food and fish releases ammonia in the aquarium water. With this high amount of ammonia can degrade the health of fish and can even cause death.

              You know, Ammonia is broken down by beneficial bacteria, ammonia breaks down to nitrite and then to nitrate and reduces toxicity. The nitrate is then removed from the water during a normal water change. This is a biological filtration process to maintain balance in the aquarium and keep it healthy.
