Interesting Facts

Let’s just face it, no one likes to waste time cleaning after their pets. This is one of the main reasons why some people prefer fish over pets like dogs and cats, pets that are a lot harder to care for. What makes fish an even greater addition to a modern household is the fact that they are quite relaxing to look at, and along with the aquariums that they live in, they can boost the ambiance in the house.

Self-cleaning fish tanks are a relatively new appearance on the market, these aquariums bringing an ideal fix to the issue of wasting time on maintenance tasks. Sure, from time to time even these aquariums might require some cleaning, but it is so rare that it does not even count. The design of most aquariums is plant-based, but others rely on more traditional filtration provided by filter cartridges or other types of waste eliminating and water cleaning methods.

Not only do they present a more convenient method to care for your pet fish, but they ensure a healthy and safe habitat for the small aquatic creatures as well. Therefore, you should not look at it as an investment made to simply convenience yourself and gain more free time but more as an investment made to create superior living conditions for the fish. Best of all, the price for the aquarium is not too high, regardless of the budget you have at your disposal being able to easily find the perfect one for you.

How to Properly Care for the Aquarium

Although manufacturers tend to advertise them as being completely maintenance free, this is not really true. Yes, little maintenance work is required and it is required so rare that it is not worth taking into consideration. But the truth is that you need to be aware of the chores you must perform as it is better to know from the starting point what is expected of you to do when owning the aquarium instead of finding out the hard way after months of owning it, potentially endangering your beloved pet fish because of it.

When it comes to the maintenance work you will have to perform on the aquarium, know that once every 3-4 months or whenever you think it is needed, you should empty the water out and thoroughly scrub the interior walls. By doing this, you ensure the environment the pet fish swim in is always 100% clean and free of dirt, gunk, and any type of impurity. Someday, maybe these aquariums will be perfect and there truly won’t be a need for you to ever lift a finger to clean them in your life. But for now, this is not the case as the aquariums are a lot less hassle when compared to their traditional counterparts.

Reasons to Make the Purchase

Some tanks come at more expensive prices, requiring you to spend a few hundreds of dollars on purchasing them, while others can cost as little as $10. Regardless of the available budget, the system that it uses, or its design, what is a certainty is the fact that this is an investment worth making. In the following, we will tell you what are the 3 main benefits of purchasing a self-cleaning aquarium, explaining in detail what you will have to gain by making this addition to your home.

  • #1 – Less maintenance work: Free time has become quite a luxury these days due to our busy schedules. Also, modern people feel more and more stressed and overwhelmed as their jobs and their lives at home require them to be constantly active. Instead of letting your lifestyle overwhelm you completely, make your life easier by investing in an aquarium that cleans itself. Maintenance work is required for this type of aquarium, but it is required 2-3 times per year. Thus, you will not have to waste 30-60 minute cleaning it every week or even more often but rather spend the extra time that you gain relaxing.
  • #2 – Healthier environment for the fish: If you have opted for fish as pets, it is clear that you like these small aquatic creatures a lot. This means that you want to do as much as you can to ensure they lead long lives and that they do not fall prey to diseases. Unfortunately, fish can be quite sensitive, the environment they swim in impacting their health in a dramatic manner. In case you are the forgetful type of person, a major issue appears, more precisely the fact that you might skip on the routine cleaning that needs to be done on the aquarium and the water in it. With a self-cleaning model, this will not be an issue anymore as the swimming environment will be kept clean and waste-free for a long time. Also, in case you go for a water garden model, there is the added benefit that the water will be provided with more oxygen than normal, enhancing the living conditions of your beloved pets.
  • #3 – More appealing design: A dirty aquarium can easily ruin the ambiance of the room. But not everyone has the time to clean the aquarium 2-3 times per week, so a messy looking tank is quite inevitable for some. The waste and toxins left behind by the fish are taken care of, meaning that it will never appear dirty, nor the water inside it. Thus, the aquarium will always serve as an ambiance booster not only a storage space for your aquatic pets.

Finding the Perfect Aquarium Simplified

Before you head to the pet store or you start to search online, you must do some hefty homework to make sure you will look for the right things and make a good investment. In this section of the article, we will show you what you must take into consideration to find the perfect aquarium for your needs and preferences, so continue to read if you are interested.

  • Make Sure It Offers a Satisfying Volume

    Have you decided how many fish you want to put into the aquarium? Make sure you figure this aspect out before you start searching for the aquarium in order to ensure you won’t be later disappointed by your purchase. If you only want to have 1-2 small fish, you can easily go with an aquarium that has a 3-5 gallon volume capacity. In case you want a more spacious tank that can handle fitting more fish, then you should look for one that offers an over 15-gallon volume.

  • Check the Aquarium’s Dimensions

    Another important aspect that you must decide before you hit the store or the online environment is the size that you want it to have. To more easily make the decision, think about where you want to place it. If you want to put it on your desk or on the nightstand, surfaces with limited free space, make sure the aquarium you choose is compact. What you should do is to take some measurements or at least note down an approximate dimension you think will be perfect for the aquarium before starting your search.

  • Look for a Quality Construction

    We cannot stress how important it is for the aquarium to be made with quality, durable materials. Unfortunately, glass is not the best choice to go with as it not only breaks easily but it scratches easily as well. The best type of construction to go with when it comes to aquariums is definitely acrylic as it is far superior in durability and scratch resistance.

  • Choose the Right System for Your Needs

    Do you prefer a water garden system or a gravity-based model? This is another aspect that you have to think about before you start your search. Both types of aquarium systems deliver the same end result – a clean, hassle-free environment for your pet fish to swim in. the main difference between them is that the water garden type provides the added benefit of being able to grow a plant at the same time. Thus, think about it carefully and reach a decision based on what you see as being the best fit for your preferences.

  • Do Not Overlook LED Lighting

    The aquarium can become a true ambiance booster only with the addition of LED lighting. The LEDs make it possible to see the fish easily even at night and they add a modern touch to the aquarium. Some higher end aquariums even feature lighting systems that mimic the natural light cycle so that the pet fish can feel as if they were in a pond outside. Therefore, this feature can serve as far more than just a simple décor booster.
