The Ultimate Guide to Low Tech Planted Aquariums: Simple Tips for Stunning Aquascapes
Are you fascinated by lush, green aquariums but worried they’re too complex or expensive? A low tech planted aquarium may be the perfect solution! Whether you’re a complete beginner or seeking a low-maintenance aquascape, this guide will walk you through everything you need to get started with a beautiful, thriving tank—without breaking the bank or needing CO2 injection.
What Is a Low Tech Planted Aquarium?
A low tech planted aquarium is an aquascape that relies on simple equipment, low lighting, and easy-care plants. Unlike “high tech” setups that require pressurized CO2 systems and intensive care, low tech aquariums focus on creating healthy aquatic environments with less hassle and at a lower cost.
- No CO2 injection required—plants get their carbon from fish respiration and ambient CO2
- Low to moderate lighting reduces algae growth and maintenance
- Easy-care aquatic plants thrive in these conditions
- Minimal fertilizers or specialized equipment needed

Benefits of Low Tech Planted Aquariums
- Beginner-friendly and budget-conscious
- Less prone to algae outbreaks
- Fewer water parameter swings
- Ideal for community fish and shrimp
- Lower ongoing maintenance
Setting Up a Low Tech Planted Tank
1. Choosing the Right Aquarium Size
While you can create low tech aquascapes in any size tank, a 10-20 gallon aquarium is ideal for beginners. Smaller tanks magnify water parameter changes, while larger tanks can require more work and cost upfront.
2. Substrate Selection
A nutrient-rich substrate is key. Popular options include:
- Aquasoil (like ADA Amazonia or Tropica)
- Eco-Complete
- Fluval Stratum
- Capped dirt (for more experienced hobbyists)
A good planted aquarium substrate helps root-feeding plants thrive and supports beneficial bacteria.
3. Lighting for Low Tech Tanks
Use an LED light rated for plant growth, but keep it moderate (20-40 lumens per liter). Too much light leads to algae, while too little will cause slow plant growth. Aim for 6-8 hours of photoperiod per day.
4. Filtration and Water Flow
A gentle hang-on-back filter or sponge filter ensures clean water without blowing your plants around. Stable water quality is more important than high-powered flow in low tech tanks.
Best Plants for Low Tech Planted Aquariums
These hardy species flourish in low light and low tech conditions:
- Anubias—attach to rocks and wood, undemanding
- Java Fern (Microsorum pteropus)—grows well on hardscape
- Cryptocoryne—stunning foliage and easy to care for
- Amazons Sword (Echinodorus)
- Vallisneria—creates a grass-like background
- Hornwort and Water Wisteria—excellent stem plants
- Mosses (Java Moss, Christmas Moss)—versatile and great for shrimp

Aquascaping Tips for Low Tech Tanks
Layout Basics
Even in simple aquariums, aquascaping principles create stunning visuals:
- Rule of Thirds: Place key hardscape or plants off-center for a more natural look.
- Layering: Use taller plants in the back, mid-sized in the middle, and carpets or mosses up front.
- Hardscape Choices: Driftwood and rocks add structure and biological benefits to the ecosystem.
Adding Fish and Shrimp
Typical low tech tanks are ideal for:
- Neon tetras, rasboras, and other small community fish
- Shrimp—especially Amanos and Neocaridinas, which help control algae
- Snails for additional clean-up
Avoid heavy plant eaters or species that disturb the substrate. See our guide to the best fish for planted aquariums.
Low Tech Planted Tank Maintenance
Water Changes
Change 20-30% of the water weekly or bi-weekly to dilute excess nutrients and prevent algae.
Fertilizing
Minimal fertilization is required. Consider:
- All-in-one liquid fertilizers (dose according to label)
- Root tabs for heavy root feeders like Cryptocoryne or Sword plants
Trimming and Plant Healthcare
Prune dead leaves and clip overgrown stems to promote healthy growth. Remove algae manually as needed.
Troubleshooting Common Problems
- Melting Plants: Crypts and swords may lose leaves at first—give them time to adapt.
- Algae: Reduce light, avoid overfeeding, or add more fast-growing plants.
- Slow Growth: Slightly increase lighting or try a small amount of fertilizer.
