Maintaining Water Quality in Your Aquarium

Uhugehomeaquarium6sually when fish get sick for no obvious reason, the actual cause is one or more water quality concerns. First of all, make sure the temperature and pH are correct for the types of fish you are keeping, then check for toxic nitrogen substances; ammonia and nitrite (NO2) should be zero, and nitrate (NO3) should be clearly below 40 ppm.

Fortunately, maintaining good water quality in aquariums has become easier thanks to superior filtration systems, lighting, and test kits. Yet, regardless of all these advancements that can make our lives easier, handling water quality issues can still be an obstacle for many aquarium fans.

Incorrect water parameters and/or out of control toxic nitrogen molecules put huge stress on the fish and therefore damage their immune systems. Given that even well-kept tanks possess foul forms of diseases and unwanted organisms, a fragile immune system makes fish susceptible to all these things. Quite often, a disorder or parasite infestation is not noticeable until it is well established and thereby challenging or hard to cure.

Cloudy Aquarium Water

Cloudiness often results from overfeeding/overstocking the tank. Overfeeding your fish can cloud your water easily as the uneaten food decomposes. At every feeding, you ought to feed no more than what your fish can consume in a one or two minute period. There are automatic feeders available so that your fish are no longer overfed. These systems are effective to use and configurable to suit your lifestyle.
Overstocking the aquarium can also result in cloudy water. Excessive waste, like too much food, gives off ammonia and nitrites. Keep in mind that you need to have one gallon of water per one inch of (mature) tropical fish. And have about three gallons of water per one inch of goldfish. As a general rule, it is always ideal to buy the largest fish tank you can pay for.

Green Water Issues

Having green water in your tank can be a result of too much light. The first thing to try lowering the light getting the aquarium. Even if your fish tank is not in strong sunlight, the fluorescent light over the aquarium may offer plenty of energy to support excessive algae growth.greenwater6 If you keep the light off entirely, the aquarium may clear in a few days. Then, you can slowly raise the light time-span until the water starts to become green again. Another action you can take is to add live aquatic plants to the tank. This actually works, presuming you can keep them growing, and the goldfish will profit from getting to nibble on the plants.

You can also avoid cloudy green water from developing in an established aquarium by adding new fish in small numbers. Essentially, you only want to add two or three fish at a time and then wait a week or so prior to adding anymore. This lets your bacteria colony to gradually adapt to the increased amount of fish waste which should remove the development of cloudy water.


Replace filter elements often, never all of them at the same time and never in the same week will the substrate get a partial deep cleaning. If a filter element gets blocked, carefully rinse it in used aquarium water to get rid of dirt parts. A filter element demands replacing only when it looks like an absolute mess. To help preserve the nitrogen cycle operating, place a few shreds of the old filter element along with the new.
