Tip 1: How to glue aquariums

In our time, the pet market is very diverse. Therefore, novice fish breeders, as a rule, acquire a ready-made aquarium. But enthusiastic aquarists with experience prefer to glue them on their own. After all, this is the way to achieve the desired size and volume.


1. In order to glue the aquarium yourself, you must first prepare materials. It is better to order glasses for it, since the machine cuts them in the workshop and the cutting accuracy will be higher. Glasses should be 8–10 mm thick, since thinner ones may not be strong enough and cannot withstand water pressure. When ordering, specify that you need glasses for the aquarium, so there is a greater likelihood that the masters will not allow the error.

2. Once you have received the glass, process their edges. To do this, carefully drive along the edge under a stream of water with a grinding block. At the same time, the edges themselves need not be processed, since the sealant with which you will glue the product seizes smooth surfaces better. Edging is necessary so that in the future you will not get hurt when installing and washing the aquarium.

3. As soon as you have finished the edges, wash the glass from dust and wipe with a cloth moistened with acetone to degrease the surfaces to be glued. At the edges of the glass with an indentation of 3-4 mm it is necessary to glue the masking tape or duct tape so that the seam from the sealant is even and neat.

4. Next, you need to take the side and rear surface of the future aquarium. They should be placed at right angles. It is better if you secure the structure with adhesive tape. Then carefully apply the sealant in the angle that forms between the surfaces of the glass. Excess sealant can be removed using a rubber spatula.

5. Similarly, you need to collect the remaining glass. The second side glass is glued to the back surface, then the outer one, and then the whole structure is placed on the bottom. The main thing is do not rush. On the glue you can take a few days. Carefully ensure that the sealant lies flat and dry thoroughly.

6. As soon as the aquarium is ready, you need to stick stiffeners. For small aquariums, they are glued arbitrarily, and for products over 50 liters in volume - along long walls. This helps reduce the water pressure on the glass.

Tip 2: How to glue the aquarium

Constructions aquariums very diverse. A regular rectangular frame aquarium is still relevant, as it is more convenient to maintain it than a round one. In addition, it is much stronger than an aquarium without a metal frame.

You will need

  • Roofing iron - strips 10 cm wide, 1.5 mm thick
  • Glass window or showcase thickness of 4.3 mm
  • Oil paint
  • Epoxy resin
  • Hardener
  • Epoxy resin remover
  • Sifted building cement
  • Plasticizer (dibutyl phthalate)
  • Glass cutter
  • Rubber gloves
  • Protective glasses
  • 150-200W soldering iron
  • Solder
  • Soldering acid
  • Knife
  • Scissors for metal
  • Kiyanka
  • File
  • Sandpaper
  • Metal working table with a vice


1. For an aquarium with a bottom size of 25x30 cm and a height of 40 cm, cut 4 metal strips 25 cm long, 4 - 30 cm each, 4 - 40 cm each. Bend the strips lengthwise so that they form a corner.

2. From strips of 25 and 30 cm solder the ends of the frame. Connect them together in strips of 40 cm. Using a file and emery paper, smooth the seams.

3. Cut the bottom, side and end walls of the glass. Their size should be 20 mm smaller than the outer edges of the aquarium. Glasses should not rest against the frame and each other. Otherwise they may burst. Wipe the glass and frame with a degreasing solvent.

4. Prepare a putty in a clean, wide dish. Pour the sifted cement. In order to smear one glass, you need 2 cups of cement. Make a hole in the cement and start pouring epoxy resin there. Stir and knead the resulting mass to the consistency of thick dough. Add a plasticizer in an amount equal to the amount of hardener (depending on resin consumption). Stir the mixture thoroughly again. If it is not liquid enough, you can add a solvent. At the end, add a hardener and mix again.

5. Turn the aquarium on its side so that the side with which you are currently working, lay on a flat surface. Roll the long rollers out of the putty and place them on the frame around the glass perimeter. Align the rollers. Place skim glass on top and press it firmly against the frame, taking into account that the glass should not touch each other in the future. In this case, due to the edges of the glass will be squeezed out an excess of putty. Remove it with a knife, without turning the frame. Put the load on the glass and leave it for about 12 hours. After 12 hours, place the aquarium vertically and use a knife to cut off the excess putty from the outside. So glue all the remaining glass. First, the side windows are glued in, then the front glass, and lastly - the bottom. After that, insulate the inside of the shelf with the putty from the inside of the frame, that is, the upper metal part of the frame. Full curing of the putty takes 48 hours.

6. Wipe the aquarium with solvent inside and out. Fill the aquarium to the top with water. Usually, aquariums made with this technology are quite tough and do not have leaks. If a leak is detected, isolate it with the same composition, pre-drying the aquarium. Drain and paint the aquarium frame with a light oil paint. Do not forget to paint the upper shelf of the aquarium.

7. Refill the tank with water for two days. This is necessary in order to remove from the joints the harmful soluble substances contained in the putty. After two days, drain the water and wash the aquarium using baking soda. Rinse it thoroughly, then fill it with water and plant the plants. Before settling the fish, it is desirable that the aquarium stood with the plants for a week or two.

Metal strips are soldered with each other overlap.
Work with metal should be carried out with glasses and gloves, since acid is used.
It is better to make more putty. If it is not enough, then add later it will be impossible.
Putty should not arbitrarily spread over the surface. If it spreads, add more cement.

Instead of roofing iron, you can take a metal corner 20x20 mm with a thickness of 3 mm. In this case, the frame must be ordered welder. The glasses are glued with a rubber-like sealant (UT-32, U-30, GSB or Aviation Grade HA).
To prevent the frame and glass from sticking to the table, put old plastic bags under it.
Excess putty can be used to isolate the upper open part of the frame.
As a cargo when gluing glass, you can use a three-liter jar of water.

Repair aquarium at home

In case of aquarium failure, some ornamental fish owners advise simply to throw it away and purchase another. If the aquarium is small (for 30-40 liters, for example), then it makes sense. And if the house for the fish is big? Already 100-liter aquariums are not cheap, even second-hand. Therefore, it is useful to find out how some breakdowns can be fixed at home by yourself.

You need to understand that repairing your own hands is not an easy task. Before starting this work, it is necessary to solve several serious issues:

  • where and how to move the fish, whether it is necessary to evacuate them at all;
  • what materials to use for repairs and where to buy them;
  • how to correct the defect or breakdown and when, after repair, the fish house can be used again for its intended purpose.

How to fix a leak?

Perhaps the leakage of water - the most common failure. One day, the fish owner notices the water on the pedestal, then it begins to drain on the floor, and the wet spot becomes more and more every day.

Leakage can occur for various reasons. When the aquarium is many years old, the sealant with which the joints of the glass walls are glued together (or the joints of the glass and the frame elements) loses its properties. He begins to crumble a little.

It so happens that the owner of the fish itself breaks tightness in any place, removing algae from the glass with a metal scraper. Anyway, the leakage appeared, and it can be fixed with your own hands.

First of all, it is necessary to determine the specific place where the sealing is broken. If the leak is in the upper or middle part of the aquarium, then you need to lower the level of aqua and use a cotton cloth to dry the place.

To prevent the maintenance of ornamental fish from deteriorating, lower the external filter tube to the water level or, if an internal filter is used, lay it on its side.

The leakage should be degreased with acetone, white spirit or alcohol from the outside (on the inside with toxic liquids should not work), dry and apply a layer of special sealant.

After that, during the day, you need to wait until the silicone is completely vulcanized, carefully clean the seam, and only then increase the water level to the norm.

Glue for aquarium

In industrial production, special silicone glue is used to make a frameless aquarium. Exactly the same should be purchased if a breakdown or seal failure is eliminated independently at home.

Silicone glue is a jelly-like mass that hardens when exposed to moisture in the air. In about 30 minutes, a mass polymerization process takes place at the gluing point.

A day after working with this glue, the frozen mass is almost impossible to break, its strength becomes almost the same as the strength of the glass surface itself. This is achieved by the fact that the composition of the silicone adhesive is silicon, which is also an element of glass.

Silicone adhesive sealant is sold in some pet stores and in almost all construction hypermarkets.

For example, sealants of the Soudal, Penosil, Titan or VIK Aquarium Silicone brands are safe for fish, perfectly maintain contact with the water environment, create strong seams. This glue can be carried out as the elimination of leaks, and full gluing. For sealing the cracks in the top cover use the same sealants.

Gluing aquarium

As a rule, gluing is done when the glass is cracked. If the crack is small and is located in the upper part of the tank, then do the same as in the case of the elimination of conventional leaks: the crack is sealed with silicone.

The worst case is when the glass surface is cracked along the entire vertical, horizontal or diagonal. It is necessary to act immediately, as the aquarium water can squeeze out the broken glass at any time.

Where to put the fish?

Immediately need to carry out the evacuation of ornamental fish and other animals. If there is a spare dwelling for aquatic inhabitants (even if of a smaller capacity), then the problem is solved quite simply: the water from the failed aquarium is poured into the spare, the plants are moved to a separate container (a jar, for example), the ground is removed.

You can begin to fix the damage. If there is a thermo bag for transporting fish, then it is also suitable as a temporary dwelling for fish. In extreme cases, you can use the usual three-liter glass jar.

When the glass is completely cracked, it is better to replace it with a new one. That is, requires gluing the aquarium.

Stages of work

The first step - remove the glass. After the dwelling for fish is cleaned and dried, the broken glass is carefully removed. In a frame aquarium, this is not easy to do: from the grooves of the frame you need to gently get as much as possible of the old silicone. As an improvised tool in this case, you can use a nail file. If the aquarium is glue, then inside and outside the cutter makes cuts to the joints.

The second step is to remove the old glue.. When the wall is removed, the entire old sealant is removed, the cleaned surfaces are degreased.

The third step is the creation of a blank. The pattern is cut new glass. Then the silicone sealant needs to be smeared with the edges of the new glass, and the surface of the construction joints.

Fourth step - installation. A new glass wall is installed in its place and fixed by wrapping it with a rope or ribbon both horizontally across the entire container and vertically. Before this little sponge silicone gently spreads on all the seams. It is better to slightly moisten the sponge in order to avoid glue sticking.

The fifth step is to consolidate the result. An hour after the first sizing, it is necessary to smear the seams with silicone a second time. Thus, guaranteed reliability of installation of a new wall is achieved.

Sixth step - integrity test. For the complete drying of the glue you need to take 1 day, and after that the aquarium is filled with water for 1-2 hours. During this time, you must carefully check the quality of work. There should be no leakage. At the same time, all foreign substances are washed out of the container.

Seventh Step - start the aquarium. Then the test volume of water is drained, and the ground is laid in the glued-up aquarium, the water for the fish and plants is poured, and the inhabitants of the artificial reservoir return.

In principle, any aquarium can be disassembled and then re-assembled. Some aquarists professionals do this to replace old sealants.

It should be understood that repairing a home for fish requires a lot of time, effort and patience, as well as having a spare home for decorative aquatic living creatures.
