These will help you make a smart purchase.
Prevention, after all, is always better than the cure.
20 Gallon Aquarium And Its Products
Taking care of these vibrant little pets is not an easy feat. It will help if you have strong vigil, dedication, and passion for making sure they are safe and healthy, lest the water turns sour and poisons your surroundings with a toxic smell – even killing the aquatic inhabitants.
Understandably so, these organisms need your assistance in their safekeeping. A sincere effort unfailingly bears fruit. When you spend on a tank and its residents, they expect you to give them the quality living conditions; for which you need to add some necessary accessories in your list of expenses.
Amenities like filters, air pumps, and food are merely one part of the additional investments; other requirements constitute a stand, lighting, water heater, algae cleansing removers, neutralizers, flakes, glass top, pebbles, corals, temperature controller, plant food and so on.
To crown your aquarium as the best 20 gallon aquarium, you need to understand the importance of the following maintenance supplies:
It is a piece of essential equipment for all the aquarium products. A filter comes in a plethora of shapes and sizes- some being a hang-on while others are canisters, fully submerged in the water. Every filter should be relative to the size and volume of the aquarium. This accessory frees you from the time-consuming method of cleaning.
It keeps the water crystal clear, and the accompanying aerobic bacteria prevents the growth of ammonia and nitrates, thus, extending the oxygen content. The inhabitants of your aquarium have a healthy environment to swim around and live.
Various brands provide additional media with the filter to help in all the three filtration processes (biological, mechanical, and chemical). They come as bio-scrubbers, mesh, activated carbon, etc, conditioning the water flow in and out of the filter.
Similar to every living creature on this Earth, fish too need oxygen for survival. Here the air pump comes into play. It is one of the most versatile pieces of accessory among the others, that incorporates mechanical means to such in the fresh air from outside and release it under the water.
The light ripples and bubbles formulated due to such a process give an enticing effect to your fish tank, while at the same time, it can work as a filter in some cases. The air pumps and filters emit a comfortable bubbling sound that engulfs your home, sometimes effectively putting your mind at ease.
LED lighting is comparatively safer for the aquarium and its residents than a regular glow bulb. Not to forget that these LEDs provide you with an array of colorful lights to choose from. Adding colored lamps to your tank can revamp it in a refreshing manner, especially if you purchase one with different modes- such as a night light, incandescent or the likes.
There is another important reason for this belonging to an essential category. LEDs usually come with timer control and consume a limited amount of power in its wake. With the timer, you can control the amount of time the fish is exposed to the light; this also helps in managing the temperature of the tank as it emits next to no heat.
Additionally, you do not feel the pocket pinch.
With the filters and air pumps doing their work, enhancers or supplements usually get overlooked. These are as much essential as the previous three products. The enhancers ( also called as supplements or conditioners ) help in the biological filtration procedure alongside the filters. They cultivate an environment, friendly enough to support a biological ecosystem of the flora and fauna to thrive.
The water conditioners remove toxic substances like chlorine from the tap water, indirectly acting as a stress-buster for the fish. They protect the fins and scales from acquiring any fatal ailments. The wastes generated and impurities housed, on one hand, in the filters are reduced, and on the other hand, excreta including decaying materials, are cleansed.
Silt, debris, and pollutants are prevented from dirtying the water- giving you sparkling water.
Plant Micronutrients: micronutrients for plants assure them of health and vibrancy that are washed away by the tap water. Chlorine or heavy cleansing elements can strip the marine flora from minerals they require to survive. Therefore, these plants too deserve a quality dose of supplements.
Factors To Consider Before Buying the Best 20 Gallon Aquarium
Your tank could also be the best 20 gallon aquarium once you take proper care of it. The recommended method of doing so, especially for the beginners, is to have adequate knowledge about the procedure of supervision and the gravity of it. r To do so, first, you have to make sure you tick the guidelines written below:
The most important point has to be the cost of the aquarium. After you purchase an aquarium, the cost might not be worrisome, however, your expenses are merely starting. To maintain an aquarium, the investment ranges between $150 to $200.
You will search for the best maintenance kits and types of equipment for your tank. Remember they will increase your initially prepared budget. If you find the cost too much to bear at the moment, it is advisable to gather the funds before taking the final step.
You must be wondering why I kept harping on the best 20 gallon aquarium; it is because this type of tank is the appropriate size for both the beginners as well as hobbyists. These tanks are best suited for providing ample space to affix the accessories. The maintenance is easy and you receive enough space to house as many fish as you want.
Compared to the mini aquariums or those measuring 10 gallons, the size in question does not cause sedimentation frequently. The2 to 5-gallon tanks are indeed economical, but they build up toxins rapidly making the place unlivable.
Next comes the weight of the tank. Glass tanks are usually heftier than the acrylic ones. Adding water and the ornaments will cause an increment in the weight. A 20-gallon tank may weigh more than 200 lbs.
Funnily enough, the weight of the aquarium is directly proportional to the location where it is situated. For a tank as large as 20 gallons a mere bookshelf will not suffice. It needs to be placed according to its weight, a sturdy stand or a table is an ideal object to carry it.
Correspondingly, there are a few dos and don’ts related to the location of your aquarium. Avoid stationing the tank anywhere near sunlight, as it is prone to algae development. Any form of temperature extremes should not be in a direct line as it will be fatal for the inhabitants- make sure it is far away from doors, windows, vents or drafts.
Before purchasing a tank, plan out the location. It should be convenient and not adding to the list of expenses. Usually, a secluded corner of a room accompanied by an electrical outlet is the best place.
The selected location is prone to get wet due to maintenance work. Ergo, waterproofing is the utmost essential. You must have an abundant area to move around tending to the fish.
Type And Number Of Fish
Fish too differ in personalities and temperaments. While there are aggressive kinds, you also find peaceful species. This difference is startling among the freshwater breeds. Map out a checklist as to which type of fish you are interested in. A random collection of fish might not be compatible and it can adversely affect their wellbeing.
Compatibility keeps a healthy environment around the tank. The fish who like to have sufficient space for swimming requires a large tank- 20 gallon is appropriate in such a case. Others include skittish fish who prefer hiding and search for small corners and nooks to feed their purpose.
How can you rule out the growth factor? Once they achieve their full size, space becomes an issue. An overcrowded tank will pose a threat to the weaker ones.
Aquarium Starter Kit
Among the pieces of equipment mentioned above, two are habitually overlooked. An algae remover and a water heater constitute similar significant features like a filter and lighting.
Algae remover comes handy as their growth is inevitable. These unwanted groups can be eliminated using a scrubber or a magnet. The magnet cleans the clusters of algae collected on the glass body of the tank. The magnet is more convenient than a pad as it can be used outside the glass as well, although it is on the expensive side.
A stable water heater to maintain the correct temperature of the tank is significant for a flourishing ecosystem. However, this object is quite often sidelined by the other parts available in an aquarium kit.
We have established that fish have different personalities, similarly, they thrive on different temperature conditions. The variety of fish you plan on adopting should receive a consistent flow of temperature, you have to carry out extensive research.
The heaters have an assortment of sizes and shapes, depending on their price. Make sure you are confident in your spending.
This section differs from people to people. It is your choice that will determine what sort of decorative item you will spend your bucks on. Whether you prefer vibrant colored stones or abstract items to be spread around, it should be safe for the inhabitants. Every item must be clean and rid of any materials that are harmful to the fish.
You have to make sure the list of the products is carefully thought of; because it will need periodic washing. Thus, the more the number, the more hassle you face.
Plants are a common decor for the fish tanks. They give a natural outlook as if an underwater colony brought to your corner. They also help in keeping the water clean, the live ones clear the place of ammonia and nitrates simultaneously acting as a shed for the fish.
Corals, rock caves and shipwrecks are some other objects than add to the rustic look of your aquarium. Furthermore, the fish get a place to hide their eggs and rest comfortably.
Food And Flakes
Feeding the fish a regular diet of flakes might seem healthy but it gradually kills their taste buds. Resultantly, they refuse to consume any. Imagine eating the same dish every day and every hour. Sounds bland, does it not?
The fishkeeping brands work tirelessly to provide mealtime relief to these fellows. They have introduced a variety of flavored flakes ranging from vegetables, meats, low fat, to staple flakes, frozen or live food.
Fish can be herbivorous, carnivorous or omnivorous. You have to feed them accordingly. However, consistently feeding them one particular food is unwise. High-quality flakes give the prescribed nutrients and vitamins to your fish, while they can also consume dry food, frozen goods, live worms, and dried shrimps.
