Q: What do you think is the most common mistake beginners make in aquascaping?

Top 7 Common Aquascaping Mistakes—And How to Avoid Them

1. Inadequate Planning and Research

Jumping straight into tank setup without a plan can lead to mismatched plants, incompatible fish, and awkward layouts.

Solution: Sketch your scape, research compatible species, and decide on a theme before you start. Consider the lighting and substrate that suit your vision.

2. Overcrowding the Aquarium

Many aquascapers add too many plants, hardscape materials, or fish in hopes of a lush, vibrant look, but this can harm both aesthetics and ecosystem balance.

Solution: Embrace the “less is more” approach, allowing room for growth and simple maintenance. Space plants and rocks to enhance focal points and visual flow.

3. Ignoring Plant Health and Selection

Choosing plants based only on appearance, or neglecting their light/CO2 requirements, often leads to poor growth and constant algae battles.

Solution: Select plants suited to your experience and tank setup. Low-tech aquariums do best with hardy species like Anubias and Java Fern.

4. Skipping Water Parameter Checks

Pro aquascaper Mikael stresses that stable water parameters are the foundation of a healthy aquarium, yet many aquascapers rarely test for ammonia, nitrate, or pH.

Solution: Use test kits weekly to keep parameters consistent. Make gradual adjustments as needed, and always dechlorinate water before changes.

5. Poor Planting Technique

Improperly planting stem or root-feeding plants can cause them to detach, rot, or fail to thrive.

Solution: Use aquascaping tweezers for gentle planting, and anchor plants firmly in the substrate. For carpet plants, plant small portions about 1-2 cm apart for better coverage.

6. Inconsistent Maintenance

Skipping regular maintenance leads to algae outbreaks, clogged filters, and declining plant health.

Solution: Establish a consistent routine: prune plants, clean the glass, siphon debris, and perform partial water changes every week. This keeps your aquascape clean and healthy.

7. Neglecting Lighting and CO2 Balance

Poorly balanced CO2 and lighting encourage algae rather than healthy plant growth. Too much or too little of either disrupts plant metabolism and aesthetics.

Solution: Select aquarium lighting suitable for your plant species and use a controllable timer. If adding CO2, monitor levels to stay within safe ranges (20–30 ppm for most aquascapes).
