RE:Discus & Planted Tanks ...

Acidicty: This is a water condition in your aquarium. Hydrogen ions in the water makes it more acid. And its nothing about the 60's and hippies, honest.
Aeration: The introduction of air. See Air pumps
Air pumps: This is a continous supply of air.

Acidic: A water condition which has a pH lower than 7.0. A trend towards acidic water may be a sign of overfeeding.

Acidic Water
Acid from fish wastes or decayed food. Acidic water can iritate gills and skin.
White water line. Plants die, fish have frayed fins. Alkaline water can destroy gill and fin tissues. Ammonia becomes more toxic.

Acidic Water with a pH of less than 7.
Acrylic A plastic material used to construct fish tanks, filters and accessories.
Activated carbon A commonly used chemical filter media.

Acidic - Water with a pH less than 7.
Acrylic - A clear plastic material used to construct aquariums. It is half the weight of glass and its refractive index is closer to that of water than glass, making it more transparent.

Acidic water will dissolve and damage the Pond Snail's shell, so this species is best kept in moderately hard, alkaline water. Feeding foods with added calcium will help the snails have stronger, healthier shells, but this is not necessary.
Feeding: ...

Acidic to slightly alkaline (pH 6.0-7.5), soft to slightly hard.
Feeding
Omnivore: small live, frozen and dry foods.

Soft, acidic water is preferred with plants and rocks being provided for hiding places. A slight current is beneficial. Schools are a must. 6 or more fish is best. Keep with other non-aggressive, small community fish.

Acid, Acidic: a pH of less than 7.
Acrylic: Plastic material used to construct fish tanks, filters and accessories.

pH: Slightly acidic dH: Soft
Temperament: Peaceful active and sometimes wierd acting fish, don't be surprised if they rest on their sides, it's normal.
Adult Size: 10in (25cm) usually smaller ...

If the pH is acidic then the water will have a low kH value. When a high kH is maintained, the pH will stay stable and will then rarely fall.

Breeding: Soft acidic water, KH below 5, temperature 25 degrees or more. Mating occurs both with pairs or in schoals. The fish usually mate in sunlight near the bottom of the tank.

Preferring soft, acidic waters, these midwater shoaling fishes feed predominantly on small crustaceans, insects, worms, and zooplankton. When spawning, they scatter their eggs and guard neither eggs nor young.

Some fish prefer acidic water, some prefer alkaline water, others prefer water with a neutral pH. (Some fish don't care too much.) ...

Soft and slightly acidic water is preferable to mimic natural conditions, though they appear to do fine in harder, slightly alkaline water.

Appears to prefer acidic, softer water but is truly hardy and adaptable in captivity.
Husbandry Information
Feeding ...

The water turns acidic: During the dry season lot of salts, humic substances and organic material reached, step by step, a higher levels while the water level was going down.

pH - Indicates how acidic or alkaline your water is. Stands for "the power of Hydrogen".

Fish adjust quite easily to the well oxygenated ammonia-free aquarium as opposed to the acidic, polluted water in the shipping bags. Immediately remove dead or dying fish. In most cases dying fish will not respond to treatment.

peat This form of dried moss can be used as a filter material to soften water and make it more acidic. peristaltic pump A dosing pump which works by using rollers to squeeze flexible tubing.

The water in the natural habitat of Discus is acidic, around a pH of 6.0-6.5; and is very soft, 0-3 dH. Discus are found in warm water with a temperature of 77-84°F (25-29°C).

Adjust the pH so that it's slighlty acidic to neutral, and make sure the water isn't too hard, preferably below 15 dGH. Set the temperature at 25 degrees at this time, and cover the tank.

2 or less, hardness of 10 or less and temperature of 78° to 84° F (26° to 29° C) Basically the more acidic and soft, the more prolific they are.
Get 6 juveniles and let them grow up together.

They require soft, acidic water, with a low pH level from 4.7 to 6.8. The water temperature has a narrow and warm range of 82 to 86 degrees.

As free carbon dioxide is the form that is toxic to fish, high toxic concentrations are only normally found in neutral or acidic waters. Most surface waters, in their natural surface state contain low concentrations of carbon dioxide (<6 mg/l).

This is because is originates from the Niger River delta where the soft acidic waters of the Niger and its streams and tributaries meet the slightly salty, alkaline water of the Delta.

I then did a little research and discovered that the water they come from is as acidic as 5.5 pH. and as soft as one degree of hardness. I also learned that they are best kept in pairs.

This tetra prefers a darker environment with several plants and soft, acidic water. They also need some open space for swimming, and a few hiding spots. Floating plants work well to filter out some of the direct light.

Spawning Hemigrammus pulcher - The "Pretty" or "Garnet" Tetra breeds readily in soft acidic water.
Spawning Rosy Barbs - Rosy barbs are easy to spawn, and no problems raising the fry.

Something with a pH lower than 7 is acidic. Something with a pH higher than 7 is basic. Water has a pH of 7 naturally, but the water you are using in your tank will be different because of the chemicals that are suspended or dissolved in the water.

● pH - pH measures whether your water is basic, acidic, or neutral. A pH of zero is the most acidic, 14 is the most basic, and 7 is neutral. Most fish prefer a pH in the range of 6.4 - 7.

They need soft and acidic water with a low PH value, a PH of 5.5 to 6 is preferable. They hardly eat dry foods, best is to feed them live foods or frozen food, like bloodworms, brine shrimp and mosquito larvae.

A male, together with 1 - 2 females in a small, well furnished tank with soft, slightly acidic water between 72ºF and 77ºF will spawn in fine leafed plants or breeding mops.

The pH scale ranges from 1 (acidic) to 14 (alkaline). A pH of 7 is neutral.

Discus come from the warm, soft, acidic waters of the Amazon River. It's no surprise then that discus thrive when these conditions are replicated in the home aquarium. For both general maintenance and breeding of discus the pH should be kept at 6.

Some fish prefer soft, acidic water, while others prefer hard and alkaline water. There are varieties that thrive in water with low mineral content, while different ones will become sickly in such conditions.

Discus prefer slightly acidic water with a pH between 6.2 - 6.6, and an alkalinity (carbonate hardness) level in the range of 1 - 3 dKH.

0 is acidic. Fish can survive in a pH range from 5.0-9.5. Most freshwater tanks should be kept slightly acidic (6.5-7.0) for egg-laying fish, and slightly alkaline (7.2-7.6) for live-bearing fish. However, there are exceptions (i.e. Cichlids 7.5-8.5).

Water should be on the acidic side. Rainwater is often used to lower the pH, however care should be taken to ensure that the water is not contaminated with toxins.

This member of the Characidae family thrives in slightly acidic water with stable water parameters. To breed Neon Tetras, separate a pair into a "breeding tank" with no lighting at first, and gradually increase lighting until spawning occurs.

They like slightly acidic water, with a pH between six and eight. They eat flake and freeze dried foods, and should occasionally be frozen foods, such as: daphania, plankton, beef heart, brine shrimp, glass worms and blood worms.

Water maintained under higher temperature also tends to be acidic.
You can also observe some mild pH fluctuations during water changes.
If you have a planted tank, you can observe considerable pH fluctuations during day and night hours.

They prefer slightly acidic water and dimly lit conditions.
Two methods of egg laying are recognized: ...

Housing: They adapt to most water conditions, although acidic water should be avoided. For best results keep them in well established tanks, and maintain a slightly alkaline pH.

Other Tetras which need acidic water include the Blue Neon Tetra - Hyphessobrycon simulans, the Flag Tetra - H. heterorhabdus, H. metae, the Loreto Tetra - H.

The Five Banded Barb prefers a well-planted tank of at least 30 gallons with soft, slightly acidic water. Rocks and driftwood can be added to the aquarium, but leave plenty of space for swimming.

Preferred conditions for most species are acidic to neutral or slightly alkaline pH and fairly soft water, although moderate hardness is tolerated after acclimatization.

Prefer a well-planted tank of at least 30 gallons with soft, slightly acidic water. Rocks and driftwood can be added to the aquarium, but leave plenty of space for swimming. The Rosy Barb is a schooling fish and enjoys being in numbers.

These fishes should be kept in small species tanks filled with moderately acidic and soft water. Starhead killies prefer rather cooler water with temperatures around 22 degrees centigrade.

It tends to be more tolerant of acidic water than other Daphnids, and often exceeds 6 mm in length.

It makes few demands, although growth is always best in soft, slightly acidic water with a nutritious bottom. In such conditions the plant produces a mass of leaves, and it flowers very frequently in optimum conditions. A.

Aquarium Requirements: Prefers bright light and soft slightly acidic water. But it will tolerate almost any normal Aquarium conditions. Fishes love to hide among the roots and enjoy playing around it. Makes a good shelter for sunny days.

They prefer water that is soft and slightly acidic (pH 5.8 to 6.2). They are shy cichlids that should be provided with adequate cover in their tanks. Driftwood and bog wood can be used to decorate their tanks.

This African Tetra , also called the Congo tetra, requires water that has soft acidic conditions.
Feeds on worms, small insects, crustaceans and plant matter.
Water, ; pH range: 6.0 - 8.0; dH range: 5.0 - 19.0.

pH: 6 to 7 (although softer, more acidic water is prefered for breeding)
General Characteristics ...

If they are kept in favorable conditions (slightly acidic, soft water with frequent water changes) discus will breed readily in the aquarium. The fry will feed on a mucus layer secreted on the parents' bodies for the first week after hatching.

We can all probably recite the definition of pH we learned in junior high physical science class: It is a logarithmic scale indicating hydrogen ion concentration which, in turn, is indicative of the acidic or basic characteristics of the liquid.

A highly desirable filter media which is very beneficial for aquariums containing plants, South American Cichlids, Tetras, Gouramis, Rasboras, Killifish, and many other species of fish originating from acidic waters.

The water temperature should be maintained at 18° - 21°C. Change 25% of the water every week. If you have hard or acidic water, you may need to add 1 teaspoon of marine salt mix per 10 litres at each change.
