The correct products and additives are essential to maintaining a vibrant and healthy freshwater aquarium. These necessities help create the ideal habitat for your aquatic life by sustaining fish health, encouraging plant growth, and maintaining water quality.
Every product has a specific function, ranging from supplements that promote plant growth to water conditioners that neutralize harmful substances. Knowing how these additives function will help you maintain the health of your aquarium and make wise decisions.
It can make a big difference to know which products to use when, whether you’re an experienced or novice aquarist. We’ll examine the different product categories, advantages, and practical applications for the ideal aquarium setup in this post.
The right products and additives can make all the difference in maintaining a healthy freshwater aquarium. These supplies, which range from algae removers and fish health supplements to water conditioners and plant fertilizers, are necessary for establishing a healthy and dynamic aquatic ecosystem. You can maintain the health of your fish and plants as well as the clarity and beauty of your aquarium by being aware of what each product does and how to use it.
Water Conditioners
Aquarium water conditioner is perhaps the most basic of all additives. They are used everywhere in aquarium keeping. The main purpose of water conditioners is to remove or neutralize toxic and harmful substances contained in tap water. Don"t worry, your tap water is perfectly safe to drink, but keep in mind that your fish need to live and breathe in it. Tap water is treated with methods that kill and remove unwanted organisms that live in it, such as bacteria and viruses that can make humans sick. Chemicals such as chlorine and chloramines are introduced at water treatment plants. If left in the water, they will damage the fish"s sensitive gills, causing your fish to suffocate and eventually die. You should find out what type of sterilization your municipality uses to disinfect your local water supply and choose a water conditioner that neutralizes the appropriate chemicals.
Additionally, a lot of aquarium water conditioners eliminate heavy metals that are present in tap water in trace amounts. Detoxification of these materials is essential for long-term aquarium maintenance because they typically accumulate in higher concentrations in aquariums. Heavy metal detoxification is the focus of several conditioners, such as Tetra AquaSafe, Kordon Novaqua Plus, and Sera Aquatan.
Additionally, there are several conditioners made expressly to cleanse fish waste; these are usually used as last resorts in cases where an aquarium malfunction has resulted in dangerously high levels of ammonia and nitrite. Because they guard against ammonia poisoning in the tiny spaces of the fish container, they are also very helpful when shipping or transporting fish. Gulfstream Ammonia-Ease, Kordon Amquel Plus, Tetra Ammonia Detox, and Sera Toxivec are products in this category.
Lastly, water conditioners frequently include additives like aloe vera to strengthen your fish’s natural "protective mucus," which helps them fend off infections and maintain good health. TetraAqua Vital and API Stress Coat+ are two of these products. Unless you have a system like reverse osmosis or a high level of water purification, using water conditioners is not necessary. Remember that using water conditioners labeled "slime guard" in marine aquariums with protein skimmers can lead to issues.
Biological Additives
Concentrated bacterial enzymes or additives added with the intention of boosting biological filtration and getting rid of or minimizing fish waste are known as biological additives. Although there are many varieties of biological additives produced by various manufacturers, there are two primary varieties that serve three distinct functions.
When you first set up your aquarium, you will probably buy the first kind of biological additive. They are designed to initiate biological filtration in an aquarium that has just been installed. The most crucial kind of filtration is biological filtration, which uses a biological filter as a component of a filtration system or as a home for the bacteria that break down fish waste. These additives help to seed the biological filter with healthy bacteria by acting as a bacterial starter. They facilitate a quicker establishment of the biological balance in the aquarium. Hagen Nutrafin Cycle, TetraAqua Bactozym, Seachem Stability, TetraAqua SafeStart, Sera Filter Biostart, and Marc Weiss Bacter Vital are a few of these products.
This first type of additive is important for the long-term health of your aquarium. Over time, only one or two strains of bacteria will dominate the aquarium. Diversity helps the filter do its job better and thus, introducing different strains of bacteria and resulting in a healthy aquarium. In addition, many aquarists, when they perform current maintenance, often damage the biological equilibrium by stripping the components of the bio-filter of their filtration system for running water or removing too much the old water in the same replacement. These additives help to restore the bio-filter preventing ammonia and nitrite outbreaks and prevent stress in fish. All the products mentioned above can be used for this purpose, but API (Aquarium Pharmaceuticals) and Tetra have developed Stress Zyme and TetraAqua Biocoryn, TetraAqua EasyBalance specifically to solve this problem.
The second type of biological additive is a decomposer. These products help to quickly decompose accumulated waste and/or detritus that accumulate in the aquarium over time. They are made from either biologically active enzymes or chemicals that oxidize waste. They chemically break down waste into simpler molecules that are processed by bacteria into nitrates. These should be used with caution, handling large amounts of waste at once can cause ammonia to spike and stress your fish. However, they can be an effective means of reducing the loss of bio-components from your aquarium. Examples of such products include TetraAqua NitrateMinus, Hagen Nutrafin Waste Control, Sera Bio Nitrivec, Kent Poly-Ox and SuperBac Biological Aquarium Cleaner. It is recommended to use these products with the first type of bio-additive to help cope with the additional release of ammonia.
Water Cleaners
Your aquarium’s appearance is influenced by the water’s clarity. With or without fish, a beautifully clean aquarium with crystal clear water makes a striking image! Products like TetraAqua CrystalWater, Sera Aquariaclear, Seachem Clarity, Kent Pro-Clear, and API Accu-Clear are included in this category.
The aquarium water frequently gets hazy when you change the water, maintain your filtration system, or remove algae from the glass. This could be an issue, particularly if you cleaned your tank in preparation for a dinner party that evening and wanted it to be truly unique! Every time they perform a water change, a lot of aquarists use water clarifiers to prevent the unavoidable 12-to 24-hour cloudiness. Furthermore, it is normal for new aquariums to become hazy; using these clarifiers is not worth the effort.
Before using, make sure the clarifier is appropriate for your type of water—fresh or salt. Additionally, since the effects of clarifiers are more noticeable in clean aquariums with washed gravel, it is preferable to use them in these settings. This is due to the fact that these products function by sedimenting the water by combining small particles into larger ones. Last but not least, it’s critical to keep an eye on the carbonate hardness of your tank, particularly if your aquarium water is soft. Certain products have the potential to lower KH, which may result in an issue with pH balance, though this is uncommon and usually not a cause for concern.
Algae control
If your water is green, there is a strong correlation between algae control and water transparency. Before attempting to use drugs, you must first attempt to mechanically remove the source of the green color in the water. Not only does green water contain algae, but it also has colonies of algae growing on ornaments, glass, and stones. One of two approaches can be used to control algae: either use additives to directly destroy the algae or deny them access to nutrients. Generally speaking, combining these two approaches yields the best results when it comes to clearing algae.
Algae control starts with preventive measures – the maintenance of the aquarium and filter, algae are powered by substances obtained from fish waste (nitrates and phosphates). Compliance with these conditions in the long term will help keep algae under control. Surprisingly, even visually clean tanks often have high phosphate levels and using products that reduce phosphate levels may slow down the growth of unwanted algae. There are two main types of phosphate control products: liquids that are added to the aquarium and precipitate the phosphates, and chemical filter media that adsorb or “bind” the phosphates where the algae cannot access them. Both are effective algae control products, but some considerations must be made. Some plants and invertebrates are more sensitive to the effects of liquid additives than chemical filtration, and liquid additives can cause harm to them. Liquid algae control products include PhosBuster Pro, Sera Phosvec, TetraAqua AlguMin and TetraAqua NitrateMinus. TetraAqua ZMF ALGO-stop depot and TetraAqua Algetten in tablet form. Phosphate adsorbing filter media include KentPhosphate sponge, AquaeEL PhosMax Basic and Chemi-Pure Elite.
After the aquarium has been cleaned and the phosphate level is quite low, this is the time to use an algaecide to destroy the remaining algae in the aquarium. Algaecides (algicida; lat. algae algae + caedo kill) are substances from the group of pesticides, used to destroy weeds (mainly algae) in water bodies. Cannot be used in aquariums containing live plants or invertebrates. They are quite effective in destroying algae and that is why they should not be used in tanks captured by algae to achieve a quick effect. Destroying a large amount of algae all at once with these products can lead to the death of fish, since a large amount of decomposing organic material quickly pollutes the aquarium – therefore, it is important to remove as much algae and waste as possible, as early as possible, before adding an algaecide. Products in this category include – TetraAqua Algizit, Sera Algovec and Aquarium Pharmaceuticals Algae Destroyer.
pH modifiers and buffers
The water that comes out of your tap has certain characteristics that are unique to your geographic location. The fish you find in a pet store are most likely not from your area; freshwater tropical fish are mostly from the Amazon, tropical regions of Asia and the Reef Lakes of Africa. All of these regions have their own unique water characteristics. One of the most important characteristics of these bodies of water is the pH or “hydrogen value”, which is an indicator of how acidic or alkaline the water is. This is important for the most sensitive species of fish, especially if you want to breed them. It is also important that the pH level remains stable throughout the day. There are two types of pH modifiers – buffered and unbuffered.
Aquarium water’s pH is altered by buffered pH modifiers, which essentially mean that the chemicals added will assist in preventing the pH from fluctuating from its initial value. As a result of biological processes like waste recycling through biological filtration, the pH in an aquarium gradually drops. This can be avoided with buffered pH modifiers. Products in this category include Kent Cichlid Buffer and API Proper pH 7.0, which are neutral adjusters.
Other pH modifiers only make short-term pH changes; if the water is hard, the pH will always go back to its initial level. Products like Sera pH-Minus and Plus, TetraAqua pH/KH Plus and Minus, and API pH UP and pH Down are included in this category. When combined with the proper buffer to stabilize the pH, these are most helpful.
When using these products, keep in mind that fish should have their pH changed gradually because they are sensitive to abrupt changes. Marine aquariums require a pH in the 8.0–8.4 range, while most freshwater aquariums can get by with a pH of 7.0–7.2, which is neutral and in the middle.
Re-Mineralizers/GH modifiers
Another geographical characteristic of water is its general hardness or GH. General hardness is a measure of the calcium and magnesium salts dissolved in water. Hard water is responsible for the hard, whitish coating inside your kettle or on the lining of your aquarium. Some regions have hard water and some have soft water. Aquatic organisms that come from different parts of the world have adapted to a certain level of water hardness, which should be replicated in order to facilitate adaptation. Some fish are sensitive to the GH of water, while others are completely indifferent. Whether they are sensitive or not, recreating natural hardness levels will help enhance coloration and stimulate natural behaviors in your fish, such as breeding.
It’s crucial to test the water before using these medications because they’re not always required. You don’t need to use one of these products if you keep fish in soft natural waters and use soft tap water. However, it would be prudent to use products like Kent Cichlid Chemistry, Seachem Lake Salt, and Sera Mineral Salt in your aquarium if you are trying to keep African cichlids and you have soft water.
Reverse osmosis (ROOS) purified water is popular among aquarists; however, it contains no salts at all and can pose a serious risk to fish if the GH isn’t restored. Your fish’s salts are literally sucked out by this "clean-desalinated" water. Since salts are essential for many biological processes, fish and plants cannot thrive in water lacking in certain salts. In these circumstances, remineralizers are required to replenish the natural salt balance without introducing heavy metals, phosphates, or nitrates from tap water. Among these products are Seachem Replenish, Seachem Equilibrium, and Kent R/O Right. It is not unnecessary to use one of these products when using RO water in freshwater aquariums.
Trace Elements
Fish consume elements found in the water itself, in various parts of the planet, in varying amounts of trace elements, and in specific kinds of biological molecules. Chromium, cobalt, copper, manganese, iodine, and other elements are among them. Traces of similar elements are present in multivitamins. These components are necessary for a number of fish biological processes. You can boost the immune system, improve reproduction, add activity, and improve the coloration of your aquarium by adding a trace element supplement.
These products are used as conditioners to mimic the "black water" (also known as Blackwater) of the Amazon. Products that imitate the "black water" of the Amazon River and its tributaries include TetraAqua ToruMin, Sera Blackwater Aquatan, and Kent Black Water Expert. These extracts enhance general health, promote natural behavior and reproduction, and aid in the incubation of fish eggs that originate in these locations. By obstructing too much light, these additives are known to stop the growth of algae and can also lower pH levels, making the water more acidic.
