Aquarium Filter System Tips

Fish excrete waste constantly just like any other living things as they swim around the water. This waste is a potential poison to fish thus it's highly essential to find a way to remove this toxin from the aquarium tank.

The process of removing this excess food, decaying matters, dangerous chemicals, fish waste products and free floating particles from aquarium water is called filtration. And the tools use is called filter.

Filters for aquariums come in all sorts of shapes, types and sizes, but they perform the same basic function, and that is to circulate the water through some form of straining or cleansing medium at such a rate that the water is kept clean physically and biologically.

Filters are categorized as 'inside', 'outside' and sub gravel; based on the location around the aquarium, but the location is not as important as the way in which it operates.

The three major categories are mechanical, biological and chemical.

Mechanical filters remove unwanted materials from the water by straining and /or the use of absorbent materials. It helps maintaining water clarity doing so.

Biological Filtration: - Unlike mechanical filtration process biological filtration involves bacteria and other microorganisms converting your fish's waste into less toxic substances through a process call cycling. Biological filter will convert your fish's toxic waste ammonia into Nitrite, and from nitrite to nitrate, which is relatively harmless.
This cycling reduces the required maintenance in your aquarium.
Chemical filtration as the name implies can remove toxins and other chemically induced material from your aquarium system with the use of activated carbon. It's necessary to change activated carbon should be changed often to have a save community.

How Poisonous Substances Your Aquarium Can Cause Fish Death

Aquarium water becomes dangerous to fish when it’s over-saturated, as a result of nitrogen cycle in the water. In this short article, we shall look at the causes and the simple way out to limit continuous death of aquarium fish.

As we are all aware, atmospheric air is made up of about 23 per cent oxygen and 76 per cent Nitrogen together with host of other gases in very minute quantities. It follows that when we put on the airflow system of our aquarium, the air pumped in contains a little oxygen and a lot of nitrogen.

This atmospheric nitrogen can lethal to fish when the water is over-saturated (over 100 per cent) saturation with this gas.

Research has shown that nitrogen embolism otherwise known as NITROGEN GAS BUBBLE DISEASE can occur with 103-118 per cent nitrogen saturation and cause a lot of fish casualties.

This condition can affect an aquarium fish when one is replacing the old aquarium water with slightly warm fresh water. The infection is characterized by the presence of small bubbles of nitrogen beneath the skin in the fins, tail or mouth, behind the eyes, and in the blood vessels.

One can prevent the disease by aerating the water to be introduced for a while in order to clear the excess nitrogen. Affected fish would be placed in a small bucket of water into, which has been passed an airstone device to properly aerate the water. The fishes are bound to recover spontaneously if the aquarist takes an immediate remedial action.

Aquarium PLants and Lighting Mini-Guide

Aquarium plants are as important to aquariums as water is to fish. Aquarium plants add more life to aquarium and make it to look beautiful while completing the aquarium community structure.

The most important thing to bear in mind with plants is to form an attractive background, leaving ample space so the fish can swim undisturbed and be seen. The tall, grassy type is best planted at intervals in rows, while the feathery ones look better when they are bunched into small clumps, which makes them to appear like branching bushes.

When planting rooted plants, hold the tips of the bunch of roots between the thumb and second finger and rest them on the sand. Now with the first finger push the upper part of the roots (where they join the stem) about 2cm into the sand. Without moving this finger scrape with the thumb and second finger some sand over any uncovered portion of the root.

When putting in rootless plants in bunches, the method explained above is repeated, but this time the lower ends of the stems are placed together and treated exactly as if they were roots.

It is important that the water surface should be right up to the lower edge of the top angle iron of the tank, so that looking from the front the water surface can not be seen and the viewer gets the impression that there is no water in the aquarium. If the level is allowed to fall below the top angle iron the tank looks like a container holding water.

Aquarium Lighting is also important for aquarium plants

This depends greatly on whether you intend to successfully grow plants or not. Lack of light causes colorful fish to fade and clanch-reds to pink, green to white. The two main methods of lighting aquarium are by the INCADESCENT and FLOURESCENT.

The total amount of light required is a matter of trial and error. Too much light will turn the water green; too little will stunt plant growth.

The lighting can be natural or artificial or a combination of both. The best position is near a north facing window. This should provide the ideal amount of indirect lights which an be supplemented by artificial light.

The lighting should be housed in wood constructed stylishly with the furniture and placed above the tank. if there is no natural day light, the lights should be left on for approximately eight hours per day.

If the water turns green, you cut down on the light.

The best light for showing off an aquarium comes from behind.
