What causes general hardness in aquarium?
by
In the aquarium industry, total hardness may be referred to as “general hardness” or “GH,” which is often measured in degrees (dGH) rather than mg/L or ppm. One dGH is equal to 17.9 mg/L or 17.9 ppm. The two most common elements that contribute to hardness are calcium and magnesium.
You can reduce your GH by replacing some of your tank water with softer water that is appropriate for your fish. For example, if you have Discus, replace at least 25% of the water with water that has a gH lower than 4. Then, use an aquarium test kit to make sure that your GH levels are now low enough for your fish.
How do you lower GH and KH in a freshwater tank?
If you want to lower pH, KH, and GH and soften your water, we recommend letting the tank acidify over time by managing minimal water changes and gradually mixing in water filtered through an RODI (reverse osmosis de-ionized) water system.
Simply add peat to a mesh bag and place it inside your filter. As the water passes through the peat, it traps the GH minerals like calcium and magnesium. By removing and replacing the peat, you remove these minerals and soften your water. There are some downsides to using peat.

How do you adjust GH and KH in an aquarium?
To raise both GH and KH simultaneously, add calcium carbonate (CaCO3). Two teaspoons per 50 Liters of water will increase both the KH and GH by about 4 dH. Alternatively, add some sea shells, coral, limestone, marble chips, etc. to your filter.
How do you balance KH and GH in an aquarium?
How do you fix high KH in a fish tank?
Simply changing the water regularly will help remove the excess waste and pollutants. This will result in removing calcium and magnesium elements within the replaced tank water. This is the easiest step you can take, and will help lower KH to reasonably low levels.
How can I lower my KH naturally?
Indian almond leaf is a favorite for lowering the KH and pH of freshwater tanks. It’s particularly popular in betta tanks. As the Indian almond leaves break down in your tank, they release tannic acid (tannins). These tannins eat away at the KH.
Is high KH harmful to fish?
A high KH is great for both fish and plants. It means the aquarium has a high resistance against pH swings. Plants and fish do best when the pH remains constant. Very low KH values cause pH levels to fluctuate because there is nothing in the aquarium water that will absorb or release hydrogen ions.
One of the consequences of having an overcrowded aquarium is quickly depleting KH in the water. If there are a lot of fish, they produce a lot of waste, and the carbonates in the water are not enough to convert them into ammonia, nitrites, and nitrates. This can make the water acidic very quickly.
What should the general hardness be in a freshwater tank?
– What Is the Ideal GH Level? GH is also measured in dGH or degrees of GH and ppm. The optimal level for freshwater aquariums is a GH level between 4 – 8 dGH or 70 – 140 ppm. While all animals need minerals, species such as livebearers, goldfish, and African cichlids are happier with higher GH levels.
How does general hardness affect fish?
In terms of aquarium terminology, general hardness measures the number of minerals in the water, namely calcium and magnesium ions. These are important minerals for many fish and invertebrates in the aquarium as they help build bone and exoskeleton, regulate metabolism, and facilitate ion exchange.
Do plants lower water hardness?
Terminalia chebula of Combretaceae family could be helpful in reducing ground water hardiness. Ground water hardness can also be removed by using seeds of Moringa Oleifera , which is independent of pH and alkalinity of water. The most effective way to reduce the hardness can grow plants “duck weed”.
Do almond leaves lower GH?
If you want a natural solution to reduce the pH levels in your aquarium, Indian almond leaf helps to achieve just that. A study has also found that Indian almond leaves can significantly decrease water hardness (GH), which can benefit those who use hard water in their aquariums.
The antibacterial and antifungal properties of Indian almond leaves are the number one reason why you should add them to your aquarium in the first place. Once you add a suitable amount of Indian almond leaves to your aquarium, they’ll act as a natural remedy for your fish to cure any infections they might have.
How many hours a day should my aquarium light be on?
How long should I keep my aquarium lights on? To provide animals and plants the lighting they need, 10 to 12 hours a day is sufficient. Installing a timer or purchasing a unit with integrated timing can make lighting easier––just set it and forget it. Keep in mind algae loves light as well.
Do fish like LED lights?
LED aquarium lights are good for almost all the fish in the aquarium hobby as well as low for medium light aquarium plants. However, most of the LED aquarium lights are not good for very light-demanding aquarium plants. So if you’re keeping such plants in your tank then LED aquarium lights may not be for you.
Do fish like light at night?
Aquarium fish do not need light and it is best that you turn it off during the night. Leaving the light on can cause stress to fish as they need a period of darkness to sleep. Too much light will cause algae to rapidly grow and make your tank look dirty. So the short answer is no, do not leave your lights on.
