Landen 60P Rimless Aquarium Tank: Crystal Clear Viewing & Simplified Filtration

A Captivating Window to Another World

The gentle sway of aquatic plants, the vibrant colors of darting fish, the quiet hum of a filter – an aquarium is more than just a tank of water; it’s a portal to another world. For centuries, humans have been captivated by the beauty and tranquility of aquatic ecosystems, bringing miniature versions of these underwater landscapes into their homes. But the true magic of an aquarium lies in its clarity, in the ability to observe its inhabitants as if peering through the surface of a crystal-clear lake. That’s where the choice of glass, and the design of the filtration system, become paramount. The Landen 60P is a kind of aquarium designed with this principle in mind.

The Science of Seeing Clearly: Low-Iron Glass Explained

Have you ever noticed how the edges of a regular pane of glass look green? That’s because standard glass, often called “float glass,” contains iron impurities. While seemingly transparent, these impurities absorb certain wavelengths of light, particularly in the red part of the spectrum. This absorption creates a subtle green tint, which becomes more pronounced as the glass gets thicker. In an aquarium, this tint can distort the colors of your fish, plants, and decorations, making them appear duller and less vibrant than they truly are.

Low-iron glass, sometimes called “extra-clear” or “optically clear” glass, addresses this issue. During the manufacturing process, the raw materials are carefully selected and refined to minimize the iron content. Typically, low-iron glass has about one-tenth the iron content of standard float glass. This significant reduction in iron drastically reduces the green tint, resulting in a much higher level of light transmittance.

Think of it like this: Imagine looking at a beautiful landscape through a slightly tinted window. The colors might be visible, but they wouldn’t be as vivid or true as they would be if you were looking through a perfectly clear window. Low-iron glass is like that perfectly clear window for your aquarium. It allows more light to pass through, illuminating your underwater world in its full glory.

But the benefits of low-iron glass extend beyond just aesthetics. The increased light transmission can also be beneficial for the health of your aquatic plants. Plants rely on light for photosynthesis, the process by which they convert light energy into chemical energy. With more light reaching your plants, they can photosynthesize more efficiently, leading to healthier growth and more vibrant colors.
Let’s delve a bit deeper into the science. The clarity of glass is quantified by its refractive index. This index measures how much light bends when it passes from one medium (like air) to another (like glass or water). Air has a refractive index of about 1.0, water is around 1.33, standard glass is about 1.52, and low-iron glass is slightly lower than standard glass, contributing to its higher clarity. This closer match in refractive index between water and low-iron glass minimizes light distortion and maximizes the viewing experience.

Beyond the Glass: Understanding Aquarium Filtration

While the clarity of the glass is crucial for seeing your aquatic world, the filtration system is essential for sustaining it. A healthy aquarium is a balanced ecosystem, and filtration plays a vital role in maintaining that balance. Filtration removes waste products, uneaten food, and other debris, preventing the buildup of harmful toxins that can harm your fish and plants.

There are three main types of filtration:

• Mechanical Filtration: This is the physical removal of particulate matter from the water. Think of it like a strainer that catches all the visible debris. Common mechanical filtration media include sponges, filter floss, and filter socks.
• Biological Filtration: This is the heart of a healthy aquarium. It relies on beneficial bacteria to break down harmful waste products. These bacteria colonize porous surfaces, such as ceramic rings, bio-balls, and even the sponge in your mechanical filter.
• Chemical Filtration: This type of filtration uses chemical media to remove dissolved pollutants from the water. Activated carbon, for example, is a common chemical filtration medium that removes odors, discoloration, and some medications.

There are various types of filters available, each with its own advantages and disadvantages:

• Canister Filters: These are external filters that sit outside the tank. They are generally powerful and offer a large capacity for filter media, making them suitable for larger aquariums.
• Hang-on-Back (HOB) Filters: These filters hang on the back of the aquarium. They are relatively easy to install and maintain, but they can be less powerful than canister filters.
• Sump Filters: These are separate tanks, usually placed beneath the main aquarium, that house the filtration equipment. Sumps offer the greatest flexibility and capacity, but they are also the most complex to set up.
• Internal Filters: These filters are placed inside the aquarium. They are typically smaller and less powerful than external filters, making them suitable for smaller tanks.

The Landen 60P utilizes a built-in rear filtration system. It’s discreetly hidden behind a glass partition at the back of the tank.

The Hidden World of the Nitrogen Cycle

The nitrogen cycle is the cornerstone of a healthy aquarium. It’s a natural process driven by beneficial bacteria that convert harmful waste products into less toxic substances. Understanding this cycle is crucial for any aquarist.

Here’s how it works:

1. Fish Waste and Decomposition: Fish produce waste, and uneaten food and decaying plant matter also contribute to the organic load in the aquarium. These materials decompose, releasing ammonia (NH3) into the water. Ammonia is highly toxic to fish, even at low concentrations.
2. Nitrosomonas Bacteria: A group of bacteria called Nitrosomonas consume ammonia and convert it into nitrite (NO2-). Nitrite is also toxic to fish, though slightly less so than ammonia.
3. Nitrobacter Bacteria: Another group of bacteria called Nitrobacter consume nitrite and convert it into nitrate (NO3-). Nitrate is much less toxic than ammonia or nitrite, but it can still be harmful at high concentrations.
4. Water Changes and Plant Uptake: Regular partial water changes help to remove nitrate from the aquarium. Aquatic plants also absorb nitrate as a nutrient, further reducing its concentration.

Establishing a “cycled” aquarium means that you have a healthy population of these beneficial bacteria in your filter media. This process, known as “cycling,” typically takes several weeks. During this time, it’s crucial to monitor ammonia, nitrite, and nitrate levels using a test kit.

Landen 60P, Section by Section:

The back filter section of the Landen 60P, as described, is thoughtfully designed to house a comprehensive filtration system within the tank’s footprint.

• Details of the back filter section: Compact design, filtration space integrated. It uses the internal space behind the tank to separate three filter spaces, facilitating the placement of biochemical cotton, activated carbon or filter cotton, and other filter materials. The filter system is easy to maintain and clean.

• The Upper Water Inlet: The upper water inlet is designed with a removable grid. This design serves two primary purposes. First, it allows for surface skimming. By drawing water from the surface, it helps to remove any oily film or floating debris, which improves light penetration and gas exchange. Second, the removable grid makes cleaning easy. Accumulated debris can be quickly removed, preventing clogs and maintaining optimal flow. Please note the size of the Inlet, is not suitable for keeping too small fish and shrimp.

• The Bottom Water Inlet: The bottom water inlet complements the surface inlet by drawing water from the lower levels of the tank. This ensures that water circulates throughout the entire tank, preventing stagnant zones and promoting a more uniform distribution of temperature and nutrients. The bottom inlet also aids in drawing settled debris towards the filter, improving overall water clarity.

• Universal Outlet: The outlet is designed to return filtered water to the tank. This part comes with a multi-angle outlet, and an adjustable angle, making it very convenient to use. It enhances water circulation, ensuring that filtered water reaches all areas of the aquarium. The base of the outlet can be disassembled for easy cleaning.

Saltwater Considerations: Protein Skimmers and More

Setting up a saltwater aquarium introduces additional complexities. One of the most significant differences is the need for a protein skimmer.

A protein skimmer, also known as a foam fractionator, is a device that removes organic waste before it breaks down into ammonia and other harmful compounds. It works by creating a large surface area of fine air bubbles. Organic molecules, such as proteins and fats, are attracted to the air-water interface and stick to the bubbles. These bubbles rise to the top of the skimmer, forming a foam that is collected in a cup and removed.

Protein skimmers are particularly important in saltwater aquariums because saltwater fish are generally more sensitive to water quality than freshwater fish. Also, the higher density of saltwater allows for more efficient foam fractionation. While the Landen 60P’s rear filtration chamber can accommodate some protein skimmers, it’s crucial to choose a model that fits within the available space.

Beyond the Basics: Aquascaping and More

Aquascaping is the art of arranging aquatic plants, rocks, driftwood, and other decorations in an aesthetically pleasing way. It’s like underwater gardening, and it can transform a simple fish tank into a stunning work of art. The Landen 60P’s clear, rimless design makes it an excellent choice for showcasing your aquascaping skills.
