Shells in the aquarium

Shells in the aquarium cannot be considered a suitable decoration, as they are almost 100% composed of calcium carbonate (like chalk or limestone), the presence of which in the aquarium affects the hardness of the water.

Although it depends mainly on the input parameters of tap water, and what water prefer the inhabitants of Your aquarium. Than, respectively, above the initial hardness of the water, the less of an impact on its settings will have no shells.

If your aquarium water is slightly alkaline and medium hard. the small amount of shells in the aquarium will not greatly affect the water parameters.

Fish species that prefer such water, are listed here.

But soft and slightly acidic water is able to more rapidly dissolve the calcium, which will lead to explicit measurement of the composition of water. And if you are in the aquarium fish and plants adapted to live in soft water, even a small increase in the hardness of the water could affect their health. For example, Characins prefer soft water, in hard they no longer spawn.

Submission to the aquarium of carbon dioxide and adding funds, lowering the pH, accelerate the process of dissolution of shells.

Plants are generally more sensitive to increased hardness of water and fish.

Some species of clams in the aquarium is necessary as a refuge or place for spawning.

Should not be put in the aquarium seashells, imeadietly edges and protrusions, which fish can get hurt.

Shell also dangerous in that curious fish, climbing in them, just get stuck inside and die, especially catfish. For this reason, place the clams in the aquarium only entrance down.

In no case do not place the aquarium in a PAINTED or LACQUERED shell.

Shells before placing in the aquarium, it is necessary to boil and purify the entire available surface. It is better to give preference to long-empty shells than those in the depth of which can still survive the remains of dead shellfish.

And by the way, if any of the shells You find particularly valuable, do NOT PLACE THEM in the aquarium, they can change texture and color. But some shells can even dissolve.

Note also on the fact whether the appropriate shells in the aquarium, usually exotic sea shells don’t fit well into the design of freshwater aquarium, and sometimes just completely not appropriate.
