How do I fix the GH in my fish tank?
by
The best way to introduce water with a low GH is to fill the aquarium with Reverse Osmosis water. This tap water purification process removes nitrates, phosphates, chlorine and minerals, and produces water that is pure. Treat the pure RO with a remineralizer for RO and you will have perfect aquarium water.
General level of hardness, also known as aquarium water hardness, is referred to as GH for short. It’s basically the measure of the many salts that are dissolved in your water. In particular, calcium and magnesium Ions. Water with a low GH is said to be softer water, and water with a high GH is considered hard.
Can GH be too high in aquarium?
Since both calcium and magnesium are essential for fish to live, GH levels should always be kept within safe levels – If it’s too high, you may risk having unwell fish & if it’s too low, they may eventually die.
GH and KH are both needed in a system for different reasons. GH is vital to a fish’s biological functions. Although KH doesn’t affect fish in the same way, its capacity to stabilize pH is reason for regular monitoring. That’s because fluctuations in pH can be fatal to fish.

How do you balance GH and KH?
Does water hardness affect pH?
The general hardness of the water affects pH but it is the buffering capacity (KH) of your water that is the more critical pH factor.
Can KH be higher than GH?
KH and GH are different and KH is not part of any GH measurement. Therefore, KH and GH can be higher or lower than one another and provide no real indication of each other. KH is a measurement of bicarbonates and carbonates and GH of total calcium and magnesium. Most salt water aquariums naturally have very high KH.
Is GH important to Koi?
Koi Carp as an example, like relatively hard water (high GH), and may need GH introducing to the pond periodically to keep water conditions suitable if the tap water is naturally soft. GH ions are used up by the fish and are also lost during periodic water changes.
How do you increase GH without increasing KH?
If you want to increase only GH but not KH, you must increase the specific ions for GH (calcium and magnesium) without including ions that affect KH (carbonates and bicarbonates). In fact, African cichlid keepers often buy or create specific salt mixes to individually raise KH or GH.
Is KH important in aquariums?
KH doesn’t affect fish directly, so there is no need to match fish species to a particular KH. Note: it is not a good idea to use distilled water in your tank. By definition, distilled water has essentially no KH. That means that adding even a little bit of acid will change the pH significantly (stressing fish).
You can have a high GH and low KH or vice versa; either reading can be raised without changing the other. However, in most tap water systems, GH and KH values tend to be affected by whether the source water has contacted limestone (CaCO3), which raises both values simultaneously.
Does high KH harm fish?
Why is KH important to your aquarium? As I touched on earlier, KH prevents acids from causing your pH to swing. Rapid changes in pH can shock and even kill your fish. So yeah, it’s something you want to avoid!
What should the pH be in a freshwater tank?
Since most aquarists keep fish from different environments in the same aquarium, it is best to find a pH that all tank inhabitants are comfortable at. Most freshwater tropical fish do best between 6.8 and 7.8, however, some species come from areas where pH can be significantly higher or lower than these values.
Does algae like high pH?
If you’re treating your pool for algae, you’ll want the pH to be a little higher than you would typically want, at about 7.8. This will kill the bacteria or algae. Based on your levels, you will either have to lower or raise the pH. If it’s too high, add a pH decreaser.
What is best aquarium pH?
In most cases, the optimum pH for nitrification is between 7 and 8 although specific filters can vary. Nitrifying bacteria are inhibited below a pH of 6. If pH drops below this point, ammonia and nitrite can accumulate in the aquarium.
Frequent water changes are the key to lowering GH and KH levels in your aquarium. Use a softening pillow on top of your filter, and add some crystals for an even better experience. Don’t forget about removing any tap stains that may be present to ensure they don’t damage anything else.
What is a normal KH and GH for aquariums?
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.
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.
Does water conditioner lower hardness?
Unlike a water softener, a water conditioner does not remove hardness particles from your water supply. It “conditions” water and changes the chemistry of the particles for a certain amount of time to keep it from building up. “Water conditioner” is a broad term for a wide variety of products and technologies.
Is it better for water to be hard or soft?
Soft water is better.
Many people believe that soft water offers a better clean for your body and your home because it doesn’t leave behind a mineral residue like hard water can. But the truth is that neither type of water offers a better or worse clean.
