Understanding the Essence of Planted Aquarium Maintenance
Aquascaping, as the name suggests, is much more than just arranging plants underwater—it's a process that demands ongoing care and attention. For me, the heart of aquascaping lies in maintaining and cleaning the aquarium to preserve its natural beauty and ecological balance.
One of the key insights from Hiten Goolab’s planted tank is that maintenance is not just about fixing problems but about nurturing the ecosystem to flourish continuously. The planted aquarium is a living artwork that evolves, and maintenance sessions are opportunities to guide its growth and health.

Respecting the Original Creation
Before starting any maintenance, it’s crucial to appreciate the original creator’s vision. Hiten Goolab’s aquarium is cherished by visitors and aquascaping enthusiasts alike, adding immense value to the gallery where it’s displayed. This respect influences how maintenance is approached—not as a disruptive act but as a collaborative effort to enhance and sustain the aquascape.

Assessing the Aquarium Before Maintenance
Every maintenance session begins with a careful evaluation of the aquarium’s current condition. In this case, the planted tank was almost perfect, but the plants had grown rather wild over recent weeks, necessitating some trimming.
Replacing moss on the driftwood was also needed because winter’s dampness had hindered its growth. Observing how light interacts with the plants revealed that certain areas, like the 'hra' Rotala in the background, lacked the vibrant red hue due to shading by shrubs and wood.
This evaluation stage is vital—it helps identify what needs trimming, replacing, or enhancing to keep the planted aquarium looking vibrant and healthy.

Choosing the Right Plants for Enhancement
To brighten shaded areas, introducing plants like Ludwigia palustris 'Super Red' can add striking color contrasts. Red plants often provide a dramatic visual impact, drawing the eye and breaking up the green monotony. In this tank, the existing red plants already added wonderful depth, but more could be introduced strategically.

Preparing for Maintenance: The Essential Steps
Preparation is the cornerstone of effective planted aquarium maintenance. Rushing into trimming or cleaning without the right setup can lead to mistakes or even harm the tank’s ecosystem. Here are some key preparatory steps to follow before starting maintenance:
- Hydrate Yourself: It may sound trivial, but when working around water, it’s easy to forget to drink. Staying hydrated ensures you stay alert and focused during the process.
- Stop the CO2 Reactor: If your aquarium uses a pressurized CO2 system, shut off the CO2 supply first. This prevents the reactor from filling with gas, which can cause issues when restarting the filter later.
- Turn Off the Filter: Close the valve on the filter hose adapter to keep water inside the inlet and outlet tubes, then disconnect the filter. This prevents water spillage and eases the cleaning process.
- Gather Your Tools: Have all your maintenance tools within reach—scissors, moss cutters, siphons, and buckets. Being organized saves time and reduces stress.
- Prepare Hoses and Buckets: Set up hoses for water changes and a bucket to collect water and debris. Using a bucket also helps you strain and reuse water where appropriate.

Mastering Moss Trimming: A Delicate Art
Moss trimming is one of the most intricate yet rewarding aspects of planted aquarium maintenance. Mosses like Riccardia chamedryfolia and Vesicularia ferriei add softness and texture but can quickly become overgrown and unruly.
To trim moss effectively, I use a small external filter (in this case, an Oase Filtosmart 200) with a hose of 16/20 diameter. This setup is perfect because it doesn’t clog easily with moss fragments and allows me to suck up trimmed moss carefully without disturbing the tank too much.
Using curved scissors, I carefully trim the moss, ensuring not to suck in large chunks that could block the hose. This technique saves water, reduces mess, and keeps the moss healthy and well-shaped.

Why Use an External Filter for Moss Trimming?
While it might seem excessive to use an external filter just for trimming moss, it’s a practical choice. It helps conserve water by capturing trimmed moss in the bucket, preventing the need for extensive water changes. Plus, it offers precise control over the trimming process without risking damage to the plants.

Trimming and Replacing Plants: Balancing Growth and Aesthetics
After moss trimming, the next step is to address the other plants in the aquarium. In Hiten’s tank, Hydrocotyle tripartita thrives everywhere, providing lush greenery with distinctive leaf shapes. However, some plants like the 'hra' Rotala in the background needed careful trimming and replacement to maintain balance.
Using ADA’s curved scissors, I trimmed the tripartite leaves that had grown too long and replaced some of the 'hra' Rotala to revive the red corner of the tank. The goal was not to over-prune but to maintain a natural, slightly wild look consistent with the South African style of the aquarium.
This approach respects the natural growth cycle of plants while preventing overgrowth that can obscure light and reduce overall tank health.

Maintaining CO2 and Fertilization Levels
Healthy plant growth depends on proper CO2 injection and fertilization. In this aquarium, ADA Brighty K and Mineral fertilizers are used alongside Seachem XL to support biological balance and supplement carbon levels.
Regular monitoring and adjustment of these inputs ensure plants remain vigorous, which in turn helps prevent algae outbreaks and keeps the aquascape looking pristine.

Cleaning and Detailing: Enhancing the Final Look
Once trimming and plant replacement are complete, it’s time to focus on cleaning and detailing. This includes removing algae from decorative elements like lava stones to create contrast and highlight the aquascape’s features.
While some aquarists prefer a natural patina of algae, I prefer a cleaner look that accentuates the hardscape and plant colors. Cleaning also prevents algae from spreading excessively and competing with plants for nutrients.

Adding Fish for Movement and Balance
Adding fish species like Sp. rasbora brings life and movement to the aquarium, complementing the planted environment. In this tank, the rasboras blend beautifully with the plants, enhancing the natural atmosphere.
Fish also contribute to the ecosystem’s health by consuming algae and waste, creating a balanced aquatic environment.

Performing Water Changes and Final Adjustments
After maintenance tasks are complete, a water change is essential to remove debris, replenish nutrients, and maintain water quality. Using a net and siphon, I perform a partial water change, ensuring minimal disturbance to the aquascape.
This final step refreshes the environment, leaving the tank ready to continue thriving until the next maintenance session.

Conclusion: The Art and Philosophy of Planted Aquarium Maintenance
Planted aquarium maintenance is more than routine cleaning—it’s an art form that blends science, patience, and respect for living ecosystems. As I often say, we are not striving for perfection but embracing the process and the connection it fosters with nature.
Each maintenance session offers a chance to observe, learn, and nurture. The planted aquarium is a dynamic creation that evolves under our care, rewarding attention with beauty, health, and tranquility.
I hope this detailed guide inspires you to approach your planted aquarium maintenance with mindfulness and enthusiasm. Remember, the joy is in the journey, not just the final result.
