Cichlasoba

[Marko Lenac]

well, I wanted to open this topic 3 weeks ago and it would look like this

[Marko Lenac]

the 3 2m tanks...

[Marko Lenac]

and the 3m tank

[Marko Lenac]

and then begin the problem. after 2 weeks catastrophe. the bottom of one of three 1,5 m tanks cracks and you all know what happened. it is the upper tank at the entrance. the room has no siphon or drain so some of the water went on the lower flat... the only thing that was good is that I came maybe 10 minutes after the problem happened. so I take the big tube for changing water and drop at least 200 liters out of the window. all the tanks in the room are new, and the stands also. what do you thing caused the problem? hope I will close some day lucky this topic...

[Marko Lenac]

this is how it looks...

[Lisachromis]

I assume your tank stand is level?

That sort of crack looks to me like a stress fracture, as if the tank was either not level, or twisted in some way.

Did you get to save the fish?

mine fear is that the entire stand started to twist under the weight. it was level when I filled the tank. I will put the aquarium down tomorrow and recheck the stand.

[Marko Lenac]

and I sawed the fishes. mine nanoluteus did just spawnd

The stand can be level without weight on it, but when you fill the tanks the stand reacts as well as the floor too. How thick was the glass base? How thick was the styrene base ? What is your floor made of ?

I agree. Now I wounder how can I make it straight? The floor is made of ceramic... The base of the aquarium is 12 mm. The styrofoam is 10mm.

Ceramic hardly gives way to pressure - untells it bursts, of course

So most likely the stand did give way - and should be the first candidate for reenforcements

how to reinforced it?

[Bas Pels]

thicker wood / metal whatever

I got a stand carrying 4 tanks: 2 160 * 50 * 30 cm, 2 half that size, thus 3 layers

It is made of 4 cm Aluminium. The problem was, the horizonal bars were bending. On 2 layers I replaced the bars by 5 cm ones, using the old ones to carry the last tank - 2 years back

no problems left, even though the tanks are made of 6 mm glass, and I don't use wood or styropore

[Lisachromis]

Did you want this as a proper blog?

[Marko Lenac]

that would be nice.

tomorrow are coming to get the broken tank... I sleep badly at night having nightmares of my cichlasoba getting wet again.

[Juan Artigas]

Marko,

I agree with Lisa, there probably was some twisting of the structure, as 12 mm is quite a respectable glass thickness for that aquarium. Also a check for strees points under the bottom glass, a good possibility is that one could have caused that kind of fracture.

If the structure twisted, you have to make it more stable. What kind of steel are you using? Are you sure the weight is evenly distributed in each column? Which is the broken tank? If the one in the lower level you can reinforce with some steel crosses in the lower frames perpendicular to the front, adding stability to columns and the whole structure.
