Here’s how to make from tap water the right aquarium water

Depending on the country and region where you live, your tap water can be unsuitable or contain harmful substances for your aquarium dwellers.

These substances may be present and here’s how you can solve the problem

In tap water, depending on quality and place, various substances are present which are not always useful in the aquarium. Some water types can also be unsuitable for your aquarium fish, plants and invertebrates.

Chlorine (and other disinfectants)

Waterworks sometimes or regularly use chlorine to sterilise (disinfect) the tap water. You can neutralise the chlorine with the help of a water conditioner ( JBL Biotopol , JBL Nano-Biotopol ).

Heavy metals

Water pipes consist of metals which reach the tap water as ions (charged particles). These can be lead, copper, zinc or others. A good water conditioner, such as JBL Biotopol or JBL Nano-Biotopol (for small aquariums) encloses these heavy metals (chelates them) and makes them harmless.

Copper

Is also classified as heavy metal and is deadly for invertebrates like shrimps. With the help of water conditioners ( JBL Biotopol C encloses and neutralises the copper. Instead of JBL Biotopol better use JBL Biotopol C when keeping invertebrates.

Pesticides & herbicides

If you live in agricultural regions there is a high probability that these problematic substances reach your tap water through the groundwater. With good activated carbon ( JBL Carbomec ultra ) you can reliably and quickly remove both substances from your water. Unfortunately water tests to determine the pesticide and herbicide content do not exist.

Soft water

Some regions have very few minerals in the mains water. Low-mineral water is known as SOFT water. This is ideal for many fish, invertebrate and plant species. However, the pH value is often not stable. With water hardener salt ( JBL Aquadur ) you can harden the water to some extent and stabilise the pH level. If you want to keep fish from Lake Malawi and Lake Tanganyika you need medium-hard water. With the special salt JBL Aquadur Malawi/Tanganjika you can transfer your soft water into harder water.

Hard water

In some regions the tap water can have a high calcium and/or magnesium concentration. Both substances increase the general hardness of the water, making your tap water hard. You often see this in the form of lime spots in your bathroom or kitchen. With the help of an osmosis system you can produce almost mineral-free water. You can mix it with your harder tap water until the desired degree of hardness has been reached. Ideally add a special osmosis salt ( JBL Aquadur ) to precisely adjust the desired hardness.

Well water

Well water can be very suitable or not suitable at all for your aquarium water. Here you should carry out a complete analysis to check its suitability. It is important to check: GH, KH, pH, NO2, NO3, PO4, Fe.
