The Rudiments Of WATER CHEMISTRY

Most aquarists will happily debate water quality to the point of being obsessive. Water is, after all, the atmosphere on which your pets depend.

It isn't necessary to have a degree in chemistry to maintain a healthy aquarium, but you will need to do some water testing.

Axolotls are extremely sensitive to water quality. You must be prepared to test the water in your tank on a weekly basis to ensure your pet's continued good health.
With that in mind, there are some basic measurements you need to at least understand to some degree.

Acidity or Per Hydrogen (pH)
The "pH" sign for most people signals an assessment of acidity. When viewed as a scale, low numbers mean greater acidity and higher numbers indicate "basic" or alkaline water.

The actual measurement is the balance in the water between hydrogen (H+) and hydroxide (OH) ions. Axolotls are freshwater creatures, so they need a pH range of 6.5 to 7.5.

With this measurement, it's easy to confuse terms. KH refers to alkalinity, which is not the same thing as "alkaline."

Alkalinity is a description of the water's ability to neutralize and absorb acid, thereby acting as a "buffer." If the KH level in water is high, there won't be many changes in the pH level, and the water will be more stable.

Specific Gravity (sg)
In its most simple terms, specific gravity measures the salinity of water. It is taken with a hydrometer or a refractometer. Since axolotl are freshwater creatures, the specific gravity of their water should be around 1.0000.
Hard vs. Soft Water
Axolotls prefer slightly hard water. If you have limescale in your cookware or around your pipes, you have hard water.

If your axolotl is living in water that is too soft, its color will fade, especially the shade of the gills. This indicates your pet is suffering from temporary anemia. You will need to add salts to the water to increase the hardness.

Since these equations can be confusing, it's best to find out in advance if the water in your area is hard or soft and consult with an experienced aquarist about the best corrective measures to test.
The variance in water quality in this regard can be so extensive, there is no one set formula to "fix" the measurement. In general, however, soft water tends to be more acidic and hard water is more alkaline in terms of pH.

The Water Parameters For DISCUS FISH

The Amazon River is full of rooting vegetation which is a direct cause of the acid nature of the water.

Before you choose your Discus you must have the water parameters correct or matching closely to the place of where you are to buy your discus Fish.

Unless you are lucky enough to live in a place where the natural tap water is Acid and Soft, you will need the use of a Reverse Osmosis filter and a HMA filter.

The RO filter will remove 99.9% of everything in the water, making the Ph around 6.2 depending on where you live. The HMA filter will remove the heavy metals and the Chlorine, which are extremely harmful to discus. The HMA will not alter the Ph which is ideal, because we can use that to blend with the RO water to make the correct Ph.

Now if you are breeding you will need the Ph to be between 6.2 and 6.5. If you are just keeping discus say in a show tank you will need the Ph between 6.7 and 7.0. With the hardness between 3 and 5GH.

I like to use 'Indian Almond Leaves' in all my discus tanks as I find it gives a natural additive to the water similar to liquids you can buy which claim to add chemicals to the water that will give you that Amazon river consistency. The top breeders in the far east use these leaves. I always favour the natural approach every time!

Temperature should be 29 degrees centigrade.

Do your water changes regularly, the often the better, and you will not go far wrong!

Balancing CO2 in the PLANTED AQUARIUM

Carbon dioxide is a crucial element of photosynthesis where plants rearrange molecules of carbon, hydrogen and oxygen to build basic sugar structures, which provide them and the rest of the food chain with energy. The right balance of carbon dioxide is important for plant growth and the continued health of your plants.

A Co2 deficiency is visible in the form of slower plant growth and a slow yet continuous rise in water pH. In many species of plants you will also notice calcium deposits on leaves, turning them a pale yellow or white depending on the severity of the condition. For many more demanding plants it is important to add additional carbon dioxide to the water as well as keeping other conditions favourable. However, too much carbon dioxide in the water can be detrimental to other aquatic life, striking a balance between the amount of oxygen and carbon dioxide is important.

In aquariums which do not contain live aquarium plants shortages of oxygen are one of the biggest problems, which can in part be corrected with air-stones which aim to offer better aeration. In the presence of excessive Co2 fish will spend a lot of time at the surface of the water, increased gilling is visibly noticeable and it seems as if the fish are struggling to breathe. With too much Co2 the fish will suffer and without enough, the plants will instead. To maintain balanced water chemistry carry out regular water changes and be proactive to changes in the aquarium environment.

It may be necessary to add additional Co2 to the aquarium when growing aquatic plants, particularly if you are more experienced an have chosen to use more exotic species. There are a variety of options available if you decide to use carbon dioxide injections in the aquarium, from commercial systems to doing it yourself. If you keep plants with high demands of carbon dioxide, the larger the plants become the greater their need will be.




Maintaining a healthy balance where water chemistry is concerned requires attention to the aquariums and the inhabitants. Problems with a lack or macronutrients become visible in plants quickly, as do problems with an overload or deficiency of carbon dioxide. If possible it is often helpful to use water testing kits to get a general feel of what is in your water and if there is anything that you could change to the benefit of the aquarium.
