Aquatic Plants 101: A Beginner's Guide to Growing Aquatic Plants

The Appeal of Planted Aquariums and How to Get Started

A planted aquarium hobby lets you enjoy the beauty of a natural water's edge right in your home. In a lush underwater garden, fish and shrimp swim freely, offering healing and relaxation just by watching. However, many people are hesitant to start, thinking it seems difficult or requires too much equipment.

In reality, with the basics down, beginners can definitely enjoy it. This guide covers everything from setting up a planted aquarium to daily maintenance, explained in an easy-to-understand way.

Gathering the Essential Equipment

Before starting a planted aquarium, let's first confirm what equipment you'll need. Understanding the role of each piece makes choosing them easier.

Aquarium Tank

For beginners, a 60cm standard tank (60cm wide × 30cm deep × 36cm tall, approximately 65 liters) is most recommended. The more water volume, the more gradual temperature and water quality changes become, making it less likely to fail. Small tanks are harder to manage and not ideal for beginners.

Lighting

Lighting is essential for aquatic plant photosynthesis. Choose a dedicated aquatic plant LED light. Aim for 8-10 hours of light per day, and using a timer keeps it consistent, which also helps prevent algae. Cheap generic LEDs don't provide enough light intensity, making it difficult for plants to grow, so be careful.

Substrate (Soil)

The substrate has a major impact on aquatic plant rooting and water quality. Aquatic soil is most recommended, as it helps maintain slightly acidic water conditions. Soils come in two types: "adsorptive" and "nutrient-rich," but the adsorptive type is easier for beginners to work with. Aim for a depth of 5-7cm.

Filter

A canister filter is best for planted aquariums. It prevents CO2 from escaping and offers high filtration capacity. Hang-on filters let CO2 escape too easily, making them unsuitable for serious planted tanks.

CO2 Injection System

CO2 injection is highly effective for promoting aquatic plant growth. A DIY fermentation CO2 kit (using sugar and yeast) is inexpensive and easy to start with, making it perfect for beginners. If you want to take it more seriously, consider upgrading to a pressurized bottle system later.

With or Without CO2 Injection—Which Should You Choose?

In planted aquariums, whether you inject CO2 directly affects the types of plants you can grow and how fast they'll grow.

With CO2 injection, most aquatic plants grow vigorously, and red-leaved plants show more vibrant color. Stem plants and rotala grow quickly, making this ideal if you want to enjoy changing layouts. However, managing CO2 levels and maintaining equipment is required.

Without CO2 injection, you can still enjoy it by choosing hardy, low-CO2 plants like anubias, willow moss, and hornwort. With less equipment, costs are lower and maintenance is simpler. Starting without CO2 and considering it later once you're more experienced is the recommended approach.

Planting and Layout Basics

Learning proper planting techniques helps plants root better and lets you enjoy them longer.

1. Lay the substrate: Create depth by layering 5cm in front and 8-10cm in the back.
2. Plant stem plants: Using tweezers, insert the stem about 1cm below a node into the substrate. Space plants 1-2cm apart so they look beautiful as they grow.
3. Plant rosette plants: Remove from pots and gently strip away rockwool. Spread the roots and plant shallowly so the growth point (bud at the base) isn't buried—that's the key.
4. Attach moss: Spread moss like willow moss thinly on driftwood or rock and tie it with cotton thread or fishing line. It will attach within 1-2 months.

The layout basics center on creating depth with "foreground, midground, and background." Simply placing short glossostigma in front, anubias in the middle, and rotala in the back creates a professional-looking result.

Trimming and Daily Maintenance

Once plants are growing, regular trimming is necessary. Neglecting this causes lower leaves to die and non-illuminated plants to weaken.

• Stem plants (rotala, hygrophila, etc.): Cut leaving 5-10cm at the top, then replant the cuttings elsewhere to propagate.
• Rosette plants (amazon sword, etc.): Cut old outer leaves at the base. Try to preserve the new growth in the center.
• Moss: Trim with scissors to shape while pruning. High density leads to internal rot, so thin it out appropriately.

After trimming, ammonia leaches from cut surfaces, so do a water change (about 1/3) the next day to prevent algae. Regular weekly water changes of about 1/3 help maintain balance.

5 Recommended Aquatic Plants for Beginners

Success with plant selection comes from starting with hardy, easy-to-grow species.

1. Anubias Nana — A classic that needs no CO2 and grows in low light. Enjoy it by attaching to driftwood or rock. Slow-growing, but extremely hardy once established.
2. Willow Moss — The go-to beginner plant. Attaching it to driftwood creates a natural look. It also serves as shelter and breeding ground for shrimp.
3. Hornwort — No need to plant; just float it in the water. It grows quickly and purifies water well, making it effective for algae control when setting up.
4. Bucephalandra — A beautiful, popular plant with iridescent shimmer on leaves. Grows in low light without CO2, with rare varieties available for collectors.
5. Rotala Rotundifolia — A fast-growing stem plant standout. With CO2, it becomes more red and stands out as a background accent.

Buy Aquatic Plants with Confidence at Botachoku

A common pitfall for beginners is buying water plants with pesticide residue. Some plants sold at aquarium shops have been treated with pesticides, which are especially harmful to shrimp and can even wipe them out completely in the worst case.

With Botachoku, you can buy directly from aquatic plant producers, minimizing these risks.

• Pesticide-free for peace of mind: Producers clearly indicate whether pesticides were used, so you can confidently choose plants safe for shrimp tanks.
• Arrives in excellent condition: Without middlemen, shipping times are shorter and plants arrive in prime condition.
• Rare and specialty varieties available: You can find rare varieties of bucephalandra and aponogeton that shops rarely stock.
• Consult directly with producers: You can ask producers directly about care and water quality before and after purchase, so beginners can confidently try new plants.

Planted aquariums are a deep and rewarding hobby once you begin. Start with hardy plants and gradually expand your variety. Get plants from trustworthy producers at Botachoku and create your ideal underwater garden.
