Alkaline water can be high in calcium or magnesium ions.
In a planted aquarium the plants will give off carbon dioxide when the lights are turned off, this will make the water become less alkaline.
The opposite of alkaline is acid.
Alkaline: A water condition which has a pH higher than 7.0.
Air Pump: A pump which is used to deliver air to the aquarium. The pump pushes air through silicon tubing and to air stones or other aquatic decor.
Alkaline Water with a pH between 7 and 14. Also known as Basic.

Alkaline - Water with a pH greater than 7.
Alkalinity - The ability of water to maintain a stable pH. Controlled by the amount of carbonate ions present in the water. Also called Buffering Capacity. See KH.
Alkaline: Water with a pH between 7 and 14. Also known as Basic.
Alkalinity: This is the measure of a solution's resistance to changes in pH.

Alkaline Water
Seashells or limestone in tank or hard water supply
Fish die. Water may be cloudy.
pH Alkaline. The pH of a Malawi tank should be somewhere between 7.8 and 8.5. You should always take this requirement into consideration when buying more fish or live plants for your tank.
Low alkaline to neutral pH is good for shrimps because invertebrate shells are alkaline in nature. Acidity is detrimental to shrimp shells (same for crabs and snails) as it reacts with its alkaline nature, causing microscopic pits.
Hard and alkaline: pH 7.6-8.6 ; GH 7 plus ; KH 10-12
Feeding
Omnivore, feed a varied diet of dried foods and frozen/live foods.

35 gallon tanks we often used undergravel filters, plus power heads
under a substrate of crushed coral.
Provide a slightly alkaline water in a large aquarium with a lot of swimming room. Hiding places must be provided through the use of plants and sometimes rocky caves. If natural behavior is desired a soft substrate should be used.
Adaptable to basic (alkaline) water, it nonetheless tends to grow better in slightly acidic water. A very extensive root system develops, spreading out for several inches.
Our water is quite alkaline, but I've bred angelfish in it with no amendments to it. Likewise softness/hardness - I have hard water, but tetras do fine in it.
The water in these lakes is quite hard and alkaline. Large schools of fish graze algae from the rocky outcrop reefs. Amongst the algae live small crustaceans which also constitute part of the diet of African cichlids.
GH will not directly affect pH although "hard" water is generally alkaline due to some interaction of GH and KH.
In Southeast Asia, Discus are raised in soft to medium hard, alkaline water (3-9 dH, pH 7.0-8.0) with temperatures ranging from 81-91°F (27-33°C).
TANK: Discus prefer large, roomy, tall tanks of at least 40" (101 cm) long, and 20" (50 cm) high.
The same holds true for hydroxide ions when excess numbers make the water alkaline.I have found that the living band of pH for fish is somewhere between 6.0 and 8.6 for most fish.
In the wild these species come from swifter moving waters that vary in pH from alkaline to blackwater environments. These fish are quite adaptable to the aquarium and like the waseri complex can develop a pet like relationship with the owner.
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.
A higher number signifies a basic, or alkaline, pH. A lower number indicates acidity.
Under normal conditions, the pH in your aquarium will vary a little over time.
A slightly alkaline pH should be used, with a level around 7.6. Bubble Eye Goldfish are omnivores, and will eat live plants for food, and also vegetables like zucchini, peas, spinach, and lettuce.
Substrate provides living space for beneficial microbes, alkaline reserve and more for a system. There may be behavioral benefits for your livestock and it looks good in the tank as well.
This means that water at pH 8 is 10 times as alkaline as water at pH 7 A reading of pH 9 indicates, therefore, 10 times the alkalinity of water at pH 8 and 100 times that of water at pH 7.
I keep mine in slightly alkaline water, with about a medium hardness. And I've even kept them in very alkaline hard water. Like 7.8 or around there. Not sure about the dH. So, no need to neccessarliy keep them in soft water.
Neutral to slighltly alkaline water, well filtered, although the fish dislike current. Water should be soft to medium hard, temperature in the lower region, and pure. Frequent small waterchanges are beneficial.
The water in the breeding aquarium MUST be soft and acidic, as the fishes are unlikely to spawn in hard, alkaline water, and furthermore egg fertility appears to be adversely affected in such conditions even if the parents do spawn.
These fish do very well in the harder, more alkaline waters that come from the taps in most parts of this country. They appreciate, and some species require, the addition of a small amount of salt in their water.
Ammonia is generally highly toxic to all organisms, even in small amounts, but in alkaline conditions, the toxicity is radically increased, and this will drastically impare Daphnia reproduction, ...
Most snails do best in harder/alkaline water. If the hardness/ph drops below a certain point, their shells will start to dissolve and/or grow improperly (the behavior seems to be based on species).
Breeding/Reproduction: To breed the Madagascar Rainbowfish, a tank should be set up with moderately hard, alkaline water. The tank must be fairly large, at least 24 inches long. and should have a good current.
0 is alkaline, and a pH of less than 7.0 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.
Commercially bred fish are more adaptible and can be even be kept in hard, slightly alkaline water.
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.
Higher numbers are alkaline substances and lower numbers are acidic substances. The pH scale is logarithmic, meaning that pH 8 is ten times more alkaline than pH 7 and a hundred times more alkaline than pH 6.
Even though pH (essentially representing the level of acid or alkaline compounds) is a controlling factor in many chemical and biological processes, its precise value is not often critical in a home aquarium.
the water can be diluted with another more alkaline, and generally harder water (see Hardness, below);
the agitation of the water can be increased, enhancing the elimination of the carbon dioxide dissolved in the water and therefore lifting the pH; ...
The pH of a solution measures how acidic or alkaline it is. pH values range from 0 to 14. A neutral solution has a pH of 7. A pH less than 7 indicates an acidic solution while a pH greater than 7 indicates an alkaline solution.
It is possible to keep and possibly breed many species of dwarf cichlids in hard alkaline water. However, there are few that will thrive in these conditions.
Though the riverine Synodontis species originate in waters which are softer and less alkaline than Lakes Tanganyika and Malawi, they have proven to be very adaptable to a variety of pH and hardness levels.
Swordtails in general make good community tank fish as long as it's a community of fish that does best in water conditions that are slightly alkaline and fairly hard (15 DH) with a pH up to 7.4 or so.
Description: Hard, alkaline water is essential for the Golden Julie. Rocky caves and hiding places are also required. Very fine gravel or sand should be used to avoid injuries while sifting sand.
Temperature Range 72°F - 78°F

The scale ranges from 0 to 14 with 0 being the most acidic, 7 being neutral and 14 being the most alkaline. It is possible to raise or lower your pH levels with water changes or chemicals (use extreme caution!) from your local pet store.
Although requirements vary somewhat by species, in general livebearers favor moderately hard, slightly alkaline water (pH of slightly above 7).
Their home waters in Lake Inle are highly alkaline, having a bed of calciferous rock. They are sensitive to large swings in temperature and pH so, they may not be the best fish for the beginning fishkeeper.
The level of water's pH can range from any where between 1-14. Water of pH 7.0 is called neutral and is neither acidic nor alkaline instead a balance of both. pH levels above 7.0 are considered alkaline and those below 7.0 are acidic.
