Why Do Aquariums Often Have Limescale?
We often see white deposits appearing and sticking to the glass in freshwater aquariums, a very normal phenomenon that comes from the evaporation of hard water.
White deposits are called Limescale, which are Calcium Deposits (calcium carbonate reacted with additional ions) that accumulate on the surface of the glass.
In aquariums with mineral-rich water (hard water), it leaves heavier elements attached when the water evaporates in a gaseous state.
Those heavy elements leave ugly white deposits around the tank.
Although these calcium residues are not harmful to the health of the fish, they can be unsightly and uncomfortable for fish watchers.

Clean With Specialized Calcium Descaling Chemicals

Things To Pay Attention To When Moving Fish To Another Place To Remove Limescale
When moving fish to another place, you should not change 100% of the new water but keep about 1/3 of the old water in the tank so that the fish can quickly adapt to a new environment.
In the city, people often use tap water after filtering. But these water sources have a slight chlorine to disinfect.
Before putting it in the aquarium, you should put the water in a bucket for 24 to 48 hours to reduce the chlorine smell.

Use a water filter to remove excess food and minerals from the water. This way, both limit stains on the tank’s walls and provide more oxygen for your fish.
Using chemicals that soften the hard water, neutralize the pH first, and especially these substances must be beneficial to the health of the fish.
The process of removing dissolved magnesium and calcium salts that cause hardness in water is called softening.
