Hardness is the measure of the resistance of water to penetration by objects such as sand or gravel.
Hardness is measured in grains per gallon (GPG) or pounds per square inch (PSI).
The higher the number, the harder the water.
Hardness is important because it affects the performance of filters and pumps.
If the hardness is too high, these devices won’t function properly.
How To Lower General Hardness In An Aquarium
The best way to reduce hardness is to add a softening agent.
There are several options available for this purpose.
If you have access to tap water, then there are also some household items that can help.
For example, baking soda can be used to soften hard water.
It works well if added directly to the tank. Baking soda will not harm fish or plants.
You can also use a product called “water conditioner” which contains sodium bicarbonate.
This product should only be used with saltwater tanks.
Water conditioners work by absorbing calcium and magnesium ions from your water.
They do not remove iron or other metals.
Another option is to purchase a water softener.
These products contain chemicals that absorb minerals from the water.
Some of them even include a filter system so that they don’t need to be changed often.
Aquariums are wonderful places to keep fish, but keeping fish requires a lot of attention.
You must be sure that all of the equipment is working correctly before adding any new fish.
Aquarium Maintenance: A Complete Guide To Keeping Fish Alive
In order to care for your fish, you’ll have to know how to maintain their environment.
Most people think that maintaining an aquarium means cleaning out the gravel and replacing the water once every few months.
But, that’s just part of the equation.
In addition to regular maintenance, you’ll want to make sure that you’re providing your fish with enough oxygen.
And, you’ll want to ensure that the temperature and pH levels remain within acceptable limits.
As you learn more about keeping fish alive, you’ll find that there are many different ways to go about doing things.
So, you’ll have to decide what method suits you best.
Most importantly, you’ll want to remember that fish are living creatures.
Treating them like pets is fine; but, treating them like livestock is unacceptable.
How To Change The General Hardness
There are various methods to change the general hardness.
Here are a few steps that you can take to reduce the alkalinity of your fish tank.
Add Sodium Bicarbonate
Sodium bicarbonate is one of the most common methods to decrease the hardness of the water.
Adding sodium bicarbonate to the water increases its alkalinity.
Alkalinity is the ability of water to neutralize acids.
Adding sodium bicarbonate removes calcium and magnesium ions from the water and replaces them with hydrogen carbonate ions.
Hydrogen carbonate is less harmful than calcium and magnesium ions.
Use Saltwater Conditioner
Saltwater conditioner is another popular method to increase the alkalinity of the water.
It does this by removing calcium and magnesium ions from water.
Saltwater conditioner is usually sold as a powder.
If you buy it, make sure that it has been mixed properly.
Also, make sure that you follow the instructions on the package carefully.
Use Tap Water
If you have access to tap (untreated) water, then you can use it to dilute the hardness of the aquarium water.
The easiest way to do this is to add 1/3 cup of tap water to each gallon of aquarium water.
Then, mix well.
Use Distilled Water
Distilled water is very pure. It doesn’t contain any impurities such as chlorine, chloramine, or ammonia.
Therefore, using distilled water will not cause any harm to your fish.
You can also use distilled water to adjust the hardness of the aquarium.
Add 3 cups of distilled water to each gallon of saltwater. Mix well.
Use Reverse Osmosis Filtered Water
Reverse osmosis filtered water is the best choice for aquariums.
It contains no chemicals or additives.
It is safe for both plants and animals.
However, if you don’t have access to reverse osmosis filtered water, then you should consider buying bottled water.
Use Dechlorinated Water
Dechlorinated water is similar to reverse osmosis water.
However, it is free of chlorine.
Chlorine can be harmful to certain breeds of fish and we would recommend leaving it out if they are particularly sensitive.
Use Carbonated Water
Carbonated water is made up of carbon dioxide gas dissolved in water.
You can find carbonated water in most supermarkets.
You should only measure out a small amount of this stuff before adding it to your tank.
Use Distilled Water With Calcium Chloride
Calcium chloride is an effective means of increasing the alkalinity of water.
It works because it reacts with other substances in the water to form calcium hydroxide.
Use Distilled Water Without Calcium Chloride
If you want to go a little easy on your fish, you can leave out the calcium chloride.
Most fish enthusiasts would recommend not just using calcium chloride, but balancing it with magnesium sulphate.
Use Distilled Water To Increase The Alkalinity Of Your Aquarium
Alkalinity is the capacity of water to dissolve minerals.
When adding distilled water to your aquarium, it increases the alkalinity of your aquarium.
Use Sea Salt For Your Fish Tanks
Sea salt is a great way of altering the pH levels of your tank and contains plenty of essential nutrients which help your fish grow healthy.
Use Epsom Salts In Your Fish Tank
Epsom salts are made up of magnesium sulfate.
They are commonly used as bath salts.
Our Final Say
We hope that our guide to changing the GH of your fish tank will improve the quality of your fish’s life and you will notice a significant difference in their energy levels.
You can also notice that the filtration system will be a lot smoother, not suffering from obstructions from increased levels of calcium.
