Cleaning the glass of the aquarium, siphoning the soil, replacing the water with fresh water should become for you regular habitual rituals, and not an unpleasant duty that you remember from time to time.

New Aquarium

The aquarium, soil and decor for it must be thoroughly washed after purchase. Prepare everything in the bathroom in advance so that it is convenient to turn and rinse the aquarium. So that, it does not slip out of your hands. Place dry, clean towels nearby, prepare a surface on which you can place the washed aquarium.

The larger and heavier the house for fish you bought, the more likely it is that two people will have to wash and carry it, think in advance this moment.

We wash my new aquarium with hot water with a dishwashing sponge and special detergent. At the end of the procedure, rinse everything as thoroughly as possible with a shower hose. The soil and decor must be washed with warm water and allowed to dry. If the aquarium is so huge that it is impossible to wash it in the bathroom, it is better to leave it at the installation site and wipe it with a special aquarium cleaner or 3% hydrogen peroxide, it does not need to be washed off with water.

Fish Already Live in the Aquarium

To clean an aquarium in which fish already live, you do not need to move them temporarily to another place, this will be unnecessary stress for them. It is also not necessary to remove the soil and completely drain the water. Our task is to maintain hygiene in the existing ecosystem, the environment familiar to your fish.

Perform Regular cleaning of the aquarium once a week at least. It includes cleaning the glass of the aquarium from the inside, siphoning the soil, replacing part of the water with fresh water. The soil siphon should be carried out as soon as it gets dirty. Usually no more than once a week.

If you don’t have enough time to clean your aquarium, you can use special aquarium products. With their regular use, you can change the water much less often, up to 1 time in 5-6 months.

Clean up sequence:

  • Remove one tenth of the water from the aquarium so as not to splash it around. Take out all the equipment in the aquarium. Wash properly and put aside the filter, thermostat and aerator. We see if a trimming is necessary for aquarium plants, if necessary, we carry out the appropriate manipulations.
  • Clean the walls of the aquarium from the inside with a kitchen sponge: the hard and soft side of the sponge allows you to remove both light and more visible plaque. In specialized stores, it will not be difficult to find magnetic brushes for cleaning the glass of an aquarium. But when using them, you need skill, since the slightest grain of sand caught under such a brush can turn into a scratch on the wall.
  • A metal scraper will help to quickly and effectively remove strong deposits from the inside of the aquarium walls. An unnecessary plastic card will serve as a handy alternative to the scraper. If your aquarium is very large, or if you have a herbalist and are afraid of damaging your plants, consider purchasing a glass cleaner with a long handle and removable attachments.

Mechanically Clean Up Aquarium

If plaque remains in hard-to-reach corners of the aquarium after scrubbing with a sponge, the surface can be scrubbed with a hard-bristled toothbrush. The toothbrush is also suitable for cleaning decorative elements. Some aquarists prefer to brush with a battery-powered electric toothbrush, but if you have a small aquarium, you will hardly need an electric toothbrush to clean it.

Further, the siphon is ground. If we see settled particles of food that have not been eaten by fish, the remains of fertilizers for plants, then it is necessary to clean the bottom of the aquarium. When choosing a siphon, you need to ensure that it matches the size of the aquarium. On thematic forums, experienced aquarists often share their impressions of using one or another siphon. Their experience will surely help you make the right choice.

Use a vacuum cleaner to carry out the soil siphon. It can be useful for you if the aquarium is very large, or if you do not want to wet your hands with water once more. In a vacuum cleaner, the key element is the filter mesh; choose it with special care. In any case, when siphoning the soil, carefully watch so that fish and other inhabitants of the aquarium do not accidentally get into the tube.

Drain The Water Partially

Now is the time to partially replace the water in the aquarium with fresh water. To do this, it is enough to drain 30% of the aquarium water and carefully pour in fresh water. Be sure to use a water conditioner: with its help, you can instantly remove chlorine and heavy metals, as well as enrich tap water with useful components.

Tap The Water

Another option is to prepare the aquarium water yourself. Although at the present time, with the availability of water conditioners, this is not always advisable. To do this, pour cold tap water into a glass container with a wide neck (a three-liter jar is suitable), cover with gauze and leave for a couple of days. The settled water no longer contains chemical additives that are in tap water and which are very harmful to fish. Bottled water from the store can also be dangerous for fish, it is not chemically suitable.

We wipe the outside of the walls with a clean dry cloth. If unsightly marks remain on the outside of the glass, they can be removed with a window cleaner.
