Aquarium Maintenance

Tips to maintain your aquarium

Good aquarium maintenance practices will lead to a healthy aquatic environment and thriving fish, providing years of joy for the hobbyist.  Jump to routine maintenance guide!

Expensive and time-consuming problems can be prevented by spending thirty minutes on maintenance every other week.


The biggest factor for maintenance is tank stability / Nitrogen Cycle. As long as everything is running properly and your fish are healthy, there is no need for any major change, even if the pH or hardness seems to be slightly out of range; only increases or decreases of the major aquarium water parameters will need your careful but immediate attention.

Water Changes :

A key part of aquarium maintenance is the water change, which should be performed about every two weeks. In most cases, 10-15% of the tank volume is sufficient. A good method is to replace the water extracted while vacuuming the gravel, which will eliminate uneaten foods and other residues that settle on the substrate.

It is highly recommended to check the water parameters of both the tank and replacement water. Most tap water (city water) contains either chlorine or chloramine. Chlorine will air out rather quickly (kept in an aerated bucked for twenty-four hours); chloramine (chloramine = chlorine + ammonia) will not. Using a water conditioner will neutralize the chlorine in both cases, but ammonia will still be present in the latter. It has to be broken down by the nitrifying bacteria present in the aquarium. This may take longer than your fish can tolerate.

Other elements of municipal water may be phosphates, iron, and other heavy metals. To find out about your tap water chemistry, call your local water company.  Well water is usually harder than tap water, but it is chlorine/chloramine free.

You will need to thoroughly check the water parameters before investing upon an aquarium as purchasing water might be an expensive proposition for effecting periodic partial water changes.

Aeration :

Regularly check the air-pump to ensure adequate air-flow and aeration. Periodically change the air stones which get clogged. You can chose air-stone as per the requirement of the aquarium livestock and for increasing the aesthetic sense of your aquarium.

Filtrations :

Regularly check the substrate of your filter to ensure adequate filtration and clean them regularly in aquarium water. Never use the tap water for cleaning the filter.  The choice of filter is very important as different species of fish can react differently to water movements. Fishes like Siamese Betta Fish, Angel fish, Ramerezi prefer peaceful water movement.  Oscar and Blood Red Parrot are comfortable in filtration system with heavy water movement.  Goldfishes are best suited with external filtration system as their fins are often entangled and sucked in internal filter system. Choosing the right filter often becomes a matter of life and death for fishes.

New Tank Syndrome

New Tank Syndrome

Those who are purchasing a new aquarium or those who are new in this hobby, this important aspect is overlooked.  For healthy and sustainable aquatic life, precautions are necessary. It is important that we mimic natural environment.  All the living species in the aquarium on account of metabolic activity, will produce waste. Which has be “disposed” without adversely affecting the health of aquarium fish and plants.  These wastes will generally decompose in natural environment without any man made intervention. However, in aquarium since the nature cannot play a direct role, it is important that adequate accessories are in place to assist such decomposition of wastes. This is done by supplanting the aquarium with filtration and aeration. Some systems incorporate bacteria capable of converting nitrates into nitrogen gas thus assisting in disposal of wastes.

While purchasing a new aquarium please be aware of these things. The bacterial colonies, involved in decomposition of wastes, take several weeks to form. During which time the aquarium is vulnerable to a condition commonly known as “new tank syndrome”.  This syndrome can also arise if the aquarium is stocked with too many fishes or the fishes are added too quickly.

Accumulation of toxic ammonia from decomposing wastes is the largest cause of fish mortality in new, poorly maintained, or overloaded aquariums.

In the artificial environment of the aquarium, the nitrogen cycle effectively ends with the production of nitrates. In order that the nitrate level does not build up to a harmful level regular partial water changes are required to remove the nitrates and introduce new, uncontaminated water.
