Does water hardness matter? My tap water is quite hard. I've noticed that other people tend to keep fish that prefer soft water with fish that are hard water... Do the fish adapt?
Thanks in advance.
Thanks in advance.
question about GH
- Thread starter jenricae
- Start date
fish in general have a wide range of adaptability with some exceptions like Discus etc. As far as what the plants need, I personally have moderately hard water and add turbo calcium(calcium cloride(CaCl)) to bring my Ca level up for some plants which otherwise would be calcium deficient. With the addition of CaCl this only alters my Gh(water softness) but not my Kh(alkalinity) Hope this helped some.

I think the hardness of the water comes of CaCO3 Calcuim Carbonate or called Calcite or preffered as Carbonates.
IN AQUARIUM IS FORMED WHEN YOU ADD CO2
Ca + H2O + CO2 (a gas) -------> CaCO3 + 2H
Or I think so but the point is You need to have Calcium in the tank (Shells, Lime stone or similar things)
It doesnt effect the plants but it makes much difference when you have Snails and other hard shell creatures

O Terry think that acidity or alcalidity(basicness) of water is measured by Ph
not Kh here are the basic caracteristics of Calcite and whrere can be found pay attention to the last line
* Color is extremely variable but generally white or colorless or with light shades of yellow, orange, blue, pink, red, brown, green, black and gray. Occasionally iridescent.
* Luster is vitreous to resinous to dull in massive forms.
* Transparency: Crystals are transparent to translucent.
* Crystal System is trigonal; bar 3 2/m
* Crystal Habits are extremely variable with almost any trigonal form possible. Common among calcite crystals are the scalenohedron, rhombohedron, hexagonal prism, and pinacoid. Combinations of these and over three hundred other forms can make a multitude of crystal shapes, but always trigonal or pseudo-hexagonal. Twinning is often seen and results in crystals with blocky chevrons, right angled prisms, heart shapes or dipyramidal shapes. A notch in the middle of a doubly terminated scalenohedron is a sure sign of a twinned crystal. lamellar twinning also seen resulting in striated cleavage surfaces. Pseudomorphs after many minerals are known, but easily identified as calcite. Also massive, fibrous, concretionary, stalactitic, nodular, oolitic, stellate, dendritic, granular, layered, etc. etc.
* Cleavage is perfect in three directions, forming rhombohedrons.
* Fracture is conchoidal.
* Hardness is 3 (only on the basal pinacoidal faces, calcite has a hardness of less than 2.5 and can be scratched by a fingernail).
* Specific Gravity is approximately 2.7 (average)
* Streak is white.
* Other Characteristics: refractive indices of 1.49 and 1.66 causing a significant double refraction effect (when a clear crystal is placed on a single line, two lines can then be observed), effervesces easily with dilute acids and may be fluorescent, phosphorescent, thermoluminescence and triboluminescent.
* Associated Minerals are numerous but include these classic associations: Fluorite, quartz, barite, sphalerite, galena, celestite, sulfur, gold, copper, emerald, apatite, biotite, zeolites, several metal sulfides, other carbonates and borates and many other minerals.
* Notable Occurrences include Pugh Quarry, Ohio; Rosiclare, Illinois; Franklin, New Jersey; Elmwood, Tennessee; Brush Creek and other Missouri, Wisconsin, Kansas and Oklahoma localities, USA; Macedonia; Andreasburg, Harz Mountains and Saxony, Germany; Brazil; Guanajuato, Mexico; Cornwall, Durham and Lancashire, England; Bombay area of India; Eskifjord, Iceland; many African localities as well as others around the world with their own unique varieties.
* Best Field Indicators are crystal habit, reaction to acid, abundance, water hardness, double refraction and especially cleavage.

I dislike doing this, but I am removing the content of this post as it is innaccurate, and stolen from a website that has specified that it's information is NOT to be reposted without specific permission. Please refrain from re-posting this info at AC. OG

Hardness of the water as we test with our GH test kits is the total of calcium and magnesium ions in the water. Co2 has little to do with GH at all. Co2 drive the pH down, by creating carbonic acid. The KH (Not the GH) buffers against rapid swings in pH. KH is vitally important to this equation and train of thought.
GH is important for plants as well as animals. Plants need both magnesium and calcium in order to grow. adnesium is often dosed, calcium is often overlooked. Many water supplies contain ample calcium so folks don't think about it a lot.
The one possible tie in that folks could make between CO2 and Hardness do lie in the use of Calcium carbonate. Cacium carbonate dissolves at a rate directly correlated to pH. Co2 drive pH down, so if we want to increase the dissolution rate of CaCo3 we can add CO2 and accomplish that task. This is what is commonly refferred to as a calcium reactor. In this action we increase both calcium (GH increases) and carbonate (Kh increases) if we then remove the CO2 we will be left with very hard very high pH water.
If you wish to increase GH without increasing KH and without waiting for CaCO3 to dissolve, then add calcium via CaCL (Prestone brand "DRiveway heet" ice melter) and increase Magnesium via MgSO4 (Epsom salts) there is a good bit of dosing informatin in the plant forum and other places on the web.
For some clarified information on KH, GH, pH, CO2 etc. try the chemistry article here at AC.

I dont have missconseption about Ph Gh and Kh but if You have remarks about the text make it so to this adress below!!! The text was just a poiner to the guy saying that acidity is measured by Kh
I dont have Calcium reactors or CO2 injectors SIMLY BECAUSE I consider my tank as a small closed eco-system and dont force changeing the water chemistry because i use fresh spring water (in which a company has breading concetion for fresh water fish and they have about 4.5 milion fish there I collect it directly from the spring in COCA-COLA botles about 20 thats 40 liters just enough for 10 % weekly change) but ???

WHy post innacurate information if that is the case? THis was not a personal attack, it was meant to clarify so the original poster was not confused or mis-guided.
