African and some Central American Cichlids.
Brackish fish such as Archers, Monos, and Scats.

Is high alkalinity bad for fish?

Aquarium fish may suffer from serious problems as a result of high alkalinity in the tank. Water that is too alkaline causes non-toxic ammonia to become toxic. Fish may have trouble breathing. It can also affect the fish’s fins and tails, damaging their growth and making them look ragged.

How do you fix hard water in a fish tank?

To soften hard water, you need to take the mineral out with a natural “water softener” such as Sera Super Peat. Another option is to use demineralized water for your fish tank. The same is true for trying to raise the pH in acidic water that is soft and doesn’t contain much mineral.

How do I lower the alkalinity in my freshwater fish tank?

The fastest, easiest way to reduce alkalinity is to dilute the aquarium water with purified, low-mineral water. Reverse-osmosis or RO units produce water with almost no dissolved minerals. You can add this water to the aquarium to water down the overly alkaline water.

Is hard water Bad for aquariums?

Most aquarium fish will adapt to moderately hard to hard water provided they are acclimated properly. Ask your local aquarium shop about the hardness and pH in their tanks and compare it to the water in your aquarium. The greater the difference, the more gradually fish should be acclimated when you bring them home.

Can aquarium plants grow in hard water?

Can aquarium plants grow in hard water? Yes, there are certain species of aquarium plants that can easily grow in hard water. Examples of such plants include Anubias, Bacopa caroliniana, Hygrophila, Marsilea hirsuta, Amazon frogbit, Java fern, and Java moss.

How do I fix high pH in my fish tank?

Here are a few recommended methods to lower the pH in your aquarium:

Chemical Solutions. Possible the most common way to lower the pH in aquariums is using a bottle of chemical solution.
Driftwood.
Peat Moss.
Catappa Leaves.
CO2 Reactors.
Water Changes.
Reverse Osmosis Units.

Is distilled water safe for fish?

Fish tanks should not be filled with distilled water because the minerals are removed from it. Minerals such as iron and calcium help the fish thrive. In addition, because fish have semi-permeable membranes, fish can experience deadly trauma in pure, distilled water.

Is reverse osmosis water good for aquariums?

Reverse Osmosis filters are highly effective and make excellent choices for aquariums, though the water will require remineralization before you add it to the tank. Reverse Osmosis is excellent at filtering contaminants, including minerals, chlorine and some larger bacteria.

Does Driftwood soften aquarium water?

Maybe or maybe not, driftwood may not be as effective as other ways of softening aquarium water but notwithstanding it is still a fine alternative. Driftwood will produce tannins in your aquarium water and most likely, your water will change into brown color. It wouldn’t harm your fishes any way.

What does general hardness mean in an aquarium?

What is aquarium GH? General hardness, also known as 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.

What makes water soft or hard in an aquarium?

It’s basically the measure of the many salts that are dissolved in your water. In particular, calcium and magnesium. Water with a low GH is said to be soft, and water with a high GH is considered hard. So, soft water has very little or no calcium and magnesium. Hard water has a lot.

Do you need to test the hardness of Your Water?

To determine the GH of your water, you have to test it. And to do that, you’ll need an aquarium test kit. This one, to be exact… Don’t worry!

Why is it important to know the hardness of fish?

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. Total hardness is particularly important when spawning fish and raising fry because calcium is critical to egg, bone and tissue development.
