              • You can examine the calcium level in your salt water aquarium by using the test kits. To maintain proper coral growth, calcium plays a significant role. The recommended level of calcium in fish tank water is approximately 380 -420 ppm.
              • Test kits provide readings derived from water and will inform you about all the water chemistries.
              • Test kits help to identify the superior level of phosphates causing algal bloom.
              • Test kits play an important role to examine the chlorine level in your fish tank. The chlorine level of the tank water should be 0 (zero).
              • You can analyze the level of ammonia in your tan water by using test kit. If your tank water contains high level of ammonia causing detrimental effect to your aquarium inhabitants.

              Some Important Water Quality Parameters​​​​

              Some potential problems are created due to an increase of various nutrient levels into your tank water. You can avoid this issue by measuring the water quality parameters with the help of test kit. Preventive measures help keep your tank water free of chemical unbalance. In this case, a test kit is a necessary complement to measure the water quality parameters.

              Ammonia​​​​

              Ammonia is highly toxic to your aquarium inhabitants if the tank contains too high levels of ammonia. In this case, ammonia shows more toxic at pH levels above 7.0 and higher temperatures while it is less harmful at pH levels below 7.0 and lower temperatures. They show detrimental effects on your aquarium inhabitants and can quickly kill them.

              It is produced by breaking down of uneaten foods and from fish waste with the activities of nitrifying bacteria. Growth and activity levels of nitrifying bacteria turn down with a pH levels of 6 or below. Generally, it is produced high levels due to over feeding of your fish, stock too many fish or as part of the cycling of a new tank.

              Symptoms of Ammonia toxin

              • A red or purple color occurs around the gills.
              • Fish moves at the surface level for grasping.
              • Fish become lethargic or rest at the bottom of the aquarium.
              • Fish become pass away.

              Preventive Measures

              If you see the above signs then you should treat the tank water with a suitable ammonia remover immediately. You should avoid overfeeding or overcrowding and keep a clean tank to prevent ammonia levels from rising in the future.

              Chlorine

              The chlorine is very harmful to fish gills and invertebrates. The tap water does contain chlorine which is not safe for fish. If you use tap water in your aquarium then you have to neutralize them with a dechlorinator before aquarium use to make it suitable for fish. The safe level of chlorine is 0 mg/l for freshwater fish.

              Normal Range: 0 mg/l for freshwater fish.

              Signs of High Chlorine Levels

              • Fish show quick and jerky movements.
              • A white tinge is seen in gills.
              • Fish appear distressed.
              • Fish jump almost from the water.

              Treatment and Preventive Measures

              • You have to adjust the tap water temperature before adding to match your tank water.
              • You can use Tetra® AquaSafe® Solution with tap water before adding to your aquarium. In this case, you should use 5 ml Tetra® AquaSafe® Solution per 5 gallons aquarium water.

              Nitrite

              Nitrites are the secondary product of the Nitrogen Cycle. They are produced from toxic ammonia through break down by beneficial bacteria. In this case, ammonia is converted to nitrite. It works as toxic waste product when good filter bacteria are not functioning.

              It hampers the oxygen supply in your fish blood. It can cause acute fish stress and delays respiration. It is less harmful than ammonia. Generally, nitrite level rise very shortly in a newly established tank than older tank. To prevent nitrate poisoning, you should test the tank water at regular basis.

              Normal Range: 0-0.2 mg/l but 0 mg/l is ideal.

              Signs of High Nitrite Levels

              • Fish grasp for breathe at the surface of the water.
              • Fish become restless.
              • Fish show quick jerky movements.
              • Fish become lethargic.
              • Gills become brown color.
              • They show rapid gill movement.
              • Fish hang near the water outlets.

              Treatment and Preventive Measures

              • Checking of water should be done regularly to catch problems early.
              • Water changes should be done regularly.
              • If nitrite level of your tank water spike, then you should change the water up to safe level.
              • Reduce fish feeding.
              • It is recommended to increase aeration with an air pump and air diffuser.
              • Always keep your tank clean by removing any dead plants or other debris.
              • You can add aquarium salt or marine salt mix 1 to 3 teaspoons per gallon of tank water to minimize nitrite toxicity.
              • You can also add 5ml Tetra® SafeStart® Solution filter bacteria per 5 gallons of your tank water.

              Nitrate

              Nitrites are produced in fish tank from waste product of biological filtration system. Generally, it is the third and final product of the Nitrogen Cycle. It builds up high levels over time in your tank. It can cause fish stress and algal bloom with very cloudy water. Nitrate poisoning occurs if regular tank maintenance is not performed over many periods. It also occurs due to overfeeding and overstocking of fish.

              Normal range: 0 - 20 mg/L for freshwater and 0 - 20 mg/L but 0 mg/l is ideal for saltwater

              Signs of High Nitrate Levels

              • It causes fish stress.
              • High nitrate level can cause algal bloom.
              • Water becomes very cloudy.
              • Fish rest on the tank bottom.
              • Loss of appetite.
              • Fish show high respiration rates with rapid gill movement.
              • Fish loss equilibrium or disorientation.
              • Listlessness, acting dazed.
              • In advanced stages, curl head to tail.

              Treatment and Preventive Measures

              • Perform 25% partial water changes which help lower nitrate levels.
              • Adding live plants also help to reduce nitrate level.
              • Amount of feed should be reduced.
              • Removing all uneaten food.
              • Overstock should be avoided.
              • Always keep your tank clean.
              • Increasing aeration into your tank water.
              • You can use nitrate-removing filter media.
              • You can also add 5 ml Tetra® Easy Balance® Solution per 5 gallons aquarium water.

              General Hardness (GH)

              General Hardness refers to the levels of calcium and magnesium of the total dissolved minerals in the water. It may also be referred to as total hardness. Water hardness effects on pH and its stability. When tank water contains a low amount of dissolved minerals then it is considered soft water while the water with higher amounts of minerals, is considered hard water. If the tank has soft water which can cause pH crashes causing fish stress in your tank.

              High hardness water usually contains high pH while soft water has a lower level of pH. Different aquatic species favor different environments. Some species of fish need hard water while others need soft water. For example, fish like African Cichlids favor higher levels of hardness whereas Tetras and Discus prefer lower levels of hardness. Generally, the hardness depends on the source of the water. If you use groundwater it tends to be harder while if you use surface water it tends to be softer.

              Total hardness is very important for spawning fish and raising fry because it contains calcium which is essential to egg, bone, and development of tissue. Besides these, some tropical fish species need very soft water for spawning and development. So, total hardness should be tested in most aquariums once a month. But if your tank contains breeding fish or raising fry, total hardness should be tested more frequently.

              Normal range: 75 - 200 mg/L

              Water Hardness and Its Effect on Fish

              Water hardness influences the pH value of your aquarium water. It also influences fish wellbeing since some basic fish illness medications are affected by water hardness and subsequently it should be considered while calculating the dose of medications.

              How Can I Decrease Water Harness? 

              Using Reverse Osmosis: You can easily soften the aquarium water by using reverse osmosis. It is the most economical and popular way to decrease water hardness in your aquarium. Reverse osmosis system can remove heavy minerals, contaminants, and metals from the water and ultimately lessen the water hardness.

              By Using Water Softening Pillows: There are many Water Softening Pillows manufacturers. They produce Water softening Pillows commercially and you can purchase and add them in your aquarium filters to soften the water hardness. They work well for the small-sized aquarium but it does not work well in a large aquarium.

              Using Peat: You can use peat to soften the water hardness. Generally, you can use it in your aquarium filter or soak for a couple of weeks using a large bucket then add it to the tank water. You can also keep the peat in a pillowcase and then submerged in tank water.

              Using Rainwater: You can also collect rainwater using a clean plastic bucket and then add it to the tank water to soften the tank water. In this case, chemical leaching should be prevented by using hygienic collection methods.

              Using Driftwood: You can also soften the aquarium water by adding driftwood. In this case, you have to use smaller pieces of driftwood. Firstly, boil it and cool it and then scrub to remove contamination if any. If you use driftwood to soften the hardness, water needs to be changed daily.

              How Can I increase the Water Hardness? 

              Using Crushed Coral: You can increase the water hardness in your aquarium by using crushed coral. In this case, you can add the crushed coral in the filters or use it as a substrate instead of gravel.

              Using Buffer Products: Buffer products help to increase general hardness and alkaline hardness. In this case, you can maintain the pH level of the water.

              Using Limestone: Limestone contains calcium and other minerals. If you use limestone, they leach out calcium and other minerals into the water column and hence increase the water hardness.

              Total Alkalinity

              The most common and most important components of alkalinity are carbonates and bicarbonates. Total Alkalinity is also known as carbonate hardness which is caused anions of carbonate (CO32-) and bicarbonate (HCO3-). Alkalinity gives a buffering facility to aquarium water. The higher the alkalinity is, the higher the buffering facility against pH changes.

              Mathematically, alkalinity can be determined by:

              Alkalinity = [HCO3 -] + 2[CO3 2-] + [OH- ] – [H+]

              In saltwater, it is essential for the formation of corals. It acts as an indicator of how stable your tank water quality is. If your tank water contains low levels of alkalinity, stimulate a sudden change of pH level of the tank water causing stress on your fish. Because low levels alkalinity will not adequately regulate pH level which potentially causes acid buildup or make a dangerous pH crash. Low pH also inhibits the growth of any live aquarium plants. The freshwater tank should have good alkalinity with 75 - 200 mg/L and above 180 mg/l for saltwater aquarium. You can increase your tank water alkalinity by changing water.

              Besides it, you can also raise the alkalinity using alkalinity enhancers available at your local pet supply store.

              To ensure sufficient levels of alkalinity for the aquarium inhabitants, total alkalinity should be tested once a month. If your tank water contains less than 50 mg/l of alkalinity, you should check the alkalinity every week or every other week. Serious problems occur when the value of alkalinity goes to low or too high. In this case, the measurement of alkalinity should be done regularly to keep up a suitable level for the fish.

              Effects of High Alkalinity on Fish

              • High alkalinity creates serious problems if it remains prolonged time. Because, it dissolves the protective mucous layer around the fish body making them naked, causing bacterial attack and infection.
              • High alkalinity also converts non-toxic ammonia to toxic ammonia causing trouble breathing.
              • High alkalinity also affects the fins and tails of fish, hampering their normal growth.
              • Fish may fail to thrive and ultimately die in a high alkaline environment.

              Effect of Low Alkalinity

              • Low levels alkalinity will not adequately regulate pH level which potentially causes acid buildup or make a dangerous pH crash.
              • Low pH also inhibits the growth of any live aquarium plants.
              • Alkalinity level below 50 mg/L is very dangerous to fish which leads to pH crash.
              • Low alkalinity adversely affects on fish health.

              Treatment and Preventive Measures

              • You should do a regular test of tap water.
              • Change water as needed to maintain proper alkalinity.
              • Increase the alkalinity of the tank water to stabilize the pH level.
              • You can also add 5ml of Tetra® EasyBalance® Solution per 5 gallons of aquarium water.
              • You can increase low alkalinity it by adding chemical buffers, such as baking soda or sodium bicarbonate to the tank water.

              Normal Range of Alkalinity: 75 - 200 mg/L for freshwater and above 180 mg/l for saltwater aquarium.

              Water pH

              pH measures the level of acid and base of your tank water where 7.0 is neutral, below 7 is acidic and above 7 is basic. The pH scale ranges from 0 to 14 where 0 means the absolute most acidic water and 14 means the absolute most basic your tank water whereas 7 denotes neutral value. It is very important for raising the healthy fish in your fish tank because low or high pH value can effect overall fish health causing stress and threat.

              Suitable pH value ranges from 6.8 - 8.4 mg/l for freshwater and 7.8 to 8.4 mg/l for saltwater. A consistent pH level is suitable for your fish. For this reason, your first step is to maintain consistently high water quality. In this case, you perform routine maintenance and partial water changes to keeping your pH levels stable. If you find the pH level unacceptable then you have to raise or lower the pH level using pH enhancers that are available in the pet business sector at a reasonable cost.

              Different species need different levels of pH. Some aquarium plants and animals can survive in a high acidic pH than others. For example, Koi fish can thrive with a pH value of 7.5 to 8.2 while oscar fish favor to live in more acidic water with a pH value of 6.5 to 7.0. Besides these, African Cichlids prefer to live in more basic water with a pH value of 8.5.

              Normal Range: 6.8 - 8.4 mg/l for freshwater and 7.8 to 8.4 mg/l for saltwater.

              How to increase your aquarium’s pH

              • To raise the pH value you can add crushed corals, limestones or perform aeration the tank water with an air pump.
              • Perform a 25% partial water change.
              • Adding peat or driftwood, you can lower the pH value.
              • Adding crushed coral, limestone or dolomite chipping, you can raise the pH level.
              • If your tank water contains pH value below 6.5 then add 1 tablet Tetra® Correct pH® per 10 gallons aquarium water.
              • Adding baking soda into your tank water, you can raise the pH levels. In this case, 1 teaspoon of baking soda per 5 gallons is generally considered as safe.

              How to Decrease Your Aquarium’s pH

              • Using peat moss is a common way to lower the aquarium pH value.
              • Adding Reverse Osmosis (RO).
              • Decreasing aeration of the aquarium.
              • Adding driftwood will soften the water and lower the pH value.
              • Increasing CO2 will lower the level of pH (planted aquariums

              Effects of pH on Fish Health

              A fish tank with a low pH can burn the fish skin while high pH can chap or chemically burn the fish skin. Generally, young fish are more susceptible to lower pH water (higher acidic) than adult fish. If your tank contains pH value of 5.0 or low which can kill off fish eggs.
