Do Bettas like hard water?
It's made of calcium carbonate (CaCO3). It will slowly leach both calcium and carbonate into your water, increasing both the general hardness (GH) and carbonate hardness (KH) of the water. It will also increase the pH. Bettas need soft, acidic water .
Do neons like Hardwater?
Hardness of between 2 and 10 degrees dH is recommended. Although soft water is undoubtedly favorable for neon tetras, these fish can manage in medium-hard water if it is of a high grade .

What water conditions do tetras need?
Tetras Water Requirements
For most tetras, pH should be between 6.8 and 7.8, alkalinity between 3° and 8° dkH (50 ppm to 140 ppm) and temperature between 75° and 80° F . If the aquarium is kept in rooms below 75°, use an Aqueon Aquarium Heater to maintain the correct temperature.
Which tropical fish prefer hard water?
Livebearers. Many livebearing species also come from Central America so Guppies, Platies, Swordtails and Mollies all do well in hard water. Mollies even appreciate salt in their water and can suffer if kept in soft freshwater with a low pH.
Does water softener hurt fish?
Commercial Water Softeners
While this water has no effect on humans, it can prove deadly to fish . Unlike reverse osmosis, this produces water that is still mineral-rich, but saturated with an unusual combination of minerals, including salt, that fish would not encounter in nature.
What do GloFish need in their tank?
All GloFish except for the danios need a heater because they are tropical fish that require temperatures of approximately 75-80°F (24-27°C) to stay healthy. If you keep them at a room temperature of 68-72°F (20-22°C), the continuous stress of being too cold can cause them to get sick.
How can we remove the hardness of water?
The presence of magnesium and calcium carbonates in water makes it temporarily hard. In this case, the hardness in water can be removed by boiling the water . When we boil water the soluble salts of Mg(HCO 3 ) 2 is converted to Mg(OH) 2 which is insoluble and hence gets precipitated and is removed.

- Boil away impurities.
- Use baking soda in your cooking water.
- Add washing soda to your laundry.
- Use a reverse osmosis filter in aquariums.
What is good betta hardness?
Bettas prefer soft water, but they do tolerate a wide range of GH between 5 – 20 DH or 70-300 ppm . Very hard water can be harmful to bettas. Indian Almond Leaves, alder cones, and mixing RO or distilled water will lower water hardness.
How do I increase the hardness in my fish tank?
You can increase your aquarium water hardness by adding crushed coral, using hard tap water, or by using remineralization products such as Seachem Equilibrium . It's best to make these changes before adding fish to avoid fish loss.
Are neon tetras hard to keep?

What water do neon tetras need?
Water temperature: Aim for somewhere between 70°F to 81°F . pH levels: Keep this below 7.0. Hardness rating: This should never exceed 10 dGH.
Can tetras live in high pH?
Cardinal tetras are generally able to survive in water that has a high pH level . This is due to their ability to adapt to many different situations. This does not mean you should not take care of a high pH level in the tank.
