Aquatic Plant Tank Setup Schedule | From Day 1 to Stable Period

To maintain a beautiful and stable aquatic plant tank, it is important to understand the process from setup to the stable period and carry out appropriate management at each stage. Here, we explain the schedule from day 1 to the stable period about 3 months later in chronological order. If you have never grown aquatic plants before, it is helpful to first confirm the basic terminology in the Aquatic Plant Growing Guide for Beginners.

Pre-Setup Preparation (Day 0)

Success with an aquatic plant tank is largely determined at the preparation stage.

Checking Required Equipment

• Tank (a standard 60cm tank is recommended for beginners)
• Substrate (choose between nutrient-rich soil or adsorbent soil depending on your needs. See the Aquatic Plant Substrate Selection Guide for detailed differences)
• Filter (an external filter is best for aquatic plant tanks)
• Lighting (LED for aquatic plant growth. Light intensity should be compared by PPFD rather than lumens for accuracy)
• CO2 injection system (cylinder-type provides stable supply and is easy to manage)
• Heater and thermostat
• Water conditioner and bacterial supplement

Preparing Layout Materials Driftwood requires tannin removal. Boiling in a large pot is the fastest method; boiling for 1-2 hours removes most of the tannins. Check the impact on water quality beforehand for stones used in stone arrangements. Limestone-based stones such as ryuuou stone raise pH and hardness, making them unsuitable for aquatic plants that prefer soft water.

Day 1: Setup and Layout

Day 1 is for setup work. Proceed carefully without rushing.

How to Lay Substrate Lay the substrate thinner in the foreground (about 3cm) and thicker in the background (about 5-8cm) to create depth. It is also effective to lay substrate fertilizer like power sand on the bottom first, then cover with soil.

Planting Aquatic Plants The trick is to plant while the water is filled to about one-third of the tank. If too much water is added, the plants will float and become difficult to plant. Stem plants should be firmly inserted into the substrate at the base using tweezers. For foreground plants, divide them 1-2 at a time and plant at 2cm intervals to create a uniform carpet later.

Filling Water and Starting Equipment After planting, fill the tank slowly. To prevent substrate disturbance, pour water from above a plate or plastic bag. After filling, start the filter, heater, CO2, and lighting.

Week 1: Managing the Nutrient Leaching Period

The first week after setup is a period when ammonia and nutrients leach out from the soil in large quantities.

Daily Water Changes During this period, perform water changes of 1/3 to 1/2 of the tank daily. Nutrient-rich soil especially has high ammonia leaching, and neglecting this can cause cloudy water or damage to plants. Use dechlorinated water for changes and match the temperature before adding.

Limiting Lighting Hours Keep lighting to about 6 hours in the early setup phase. Exposing the tank to long lighting periods before bacteria are established risks an explosion of algae.

CO2 Injection Start CO2 injection in line with lighting hours. Start at about 1 bubble per second and adjust while checking concentration with a drop checker. If you're unsure about which equipment to use, refer to the CO2 Injection System Selection Guide.

Weeks 2-3: Bacterial Colonization Period

From week 2 onward, bacteria begin to gradually establish themselves in the filter.

Adjusting Water Change Frequency Gradually reduce water change frequency—once every 2 days in week 2, and once every 3 days in week 3. However, if water quality tests (ammonia and nitrite) show poor results, increase frequency again. When ammonia and nitrite reach zero, it is evidence that bacteria have sufficiently established.

Diatom Algae Appearance The appearance of brown algae (diatoms) during this period is a normal process. Remove from glass surfaces with a scraper, and introduce otocinclus or Yamato shrimp to address diatoms on plants. However, only introduce fauna after ammonia and nitrite have sufficiently declined.

Checking Plant Growth If stem plant apical shoots begin to grow, that is a good sign. Foreground plants are in the rooting stage, so lack of visible growth is not a concern. Remove dead lower leaves regularly.

Weeks 4-6: Growth Acceleration Period

This is when bacteria have stabilized and plants begin serious growth.

Extending Lighting Hours Extend lighting to 8-10 hours. Accelerated plant growth with plants outcompeting algae is the ideal state.

Beginning Fertilizer Addition Start adding liquid fertilizer as soil nutrients begin to be consumed. Begin with a focus on potassium and trace elements, starting small and adjusting based on plant response. Nitrogen and phosphorus often continue to be supplied from the soil, so avoid over-dosing.

First Trimming Perform the first trim when stem plants reach the water surface. Replant the cut portions to increase bushiness. If foreground plants are beginning to spread horizontally, guide runners to areas of lower density. Basic trimming procedures can be found in the Aquatic Plant Trimming Complete Guide.

Months 2-3: Transition to Stable Period

The tank enters a stable period with stable water conditions and vigorous plant growth.

Weekly Regular Maintenance Weekly water changes of about 1/3 are sufficient. During this time, also clean the glass, remove dead leaves, and check filter flow.

Continued Algae Prevention Even in the stable period, imbalanced nutrients cause algae. Green filamentous algae often result from excess phosphate; black beard algae from insufficient CO2. When algae appears, identify the cause and adjust conditions.

Regular Plant Trimming Make trimming every 2-3 weeks a habit. However, cutting large amounts at once disrupts nutrient balance and causes algae. The trick is to cut about 1/3 of the total.

Record Keeping for Successful Setup

Keeping daily records is extremely important for successful aquatic plant tank setup. At minimum, record the date, time, and amount of water changes; water quality test results (ammonia, nitrite, nitrate, and pH); amounts of fertilizer and CO2 added; lighting hours; and the condition of plants and fauna. Managing this in smartphone notes or spreadsheets makes it easy to review later. Taking photos regularly allows you to visually track plant growth changes. Especially when problems occur, being able to review management conditions beforehand greatly helps identify causes. Once the tank enters the stable period, you can reduce recording frequency, but it is recommended to continue recording at least water change dates and water quality test results. Many experienced aquarists find that the habit of record-keeping greatly improves tank management quality.

Mindset for Overcoming Early Troubles

During the setup period, problems are likely to occur, but the stable period can definitely be reached by handling them calmly without rushing.
