The Ultum Nature Systems (UNS) Foresta Paludarium range has quickly become a favourite among hobbyists looking to recreate stunning tropical ecosystems at home. Combining the elegance of a rimless low-iron glass enclosure with dimensions specifically designed for terrestrial and semi-aquatic environments, the Foresta series provides the perfect canvas for building immersive rainforest-inspired displays.
Unlike traditional aquariums or terrariums, a paludarium combines both land and water elements within a single enclosure. The result is a living ecosystem where tropical plants, mosses, hardscape, and aquatic features work together to create a miniature slice of nature.
If you’re new to paludariums, the process can seem intimidating at first. However, with careful planning and the right approach, setting up a successful UNS Foresta Paludarium is easier than many people realise.
In this beginner-friendly guide, we’ll walk through every stage of the setup process, from choosing your design and installing drainage layers to planting, lighting, and long-term maintenance.
What Is a Paludarium?
A paludarium is an enclosure that combines terrestrial and aquatic environments.
Typically, a paludarium includes:
- Land areas
- Water sections
- Tropical plants
- Mosses
- Hardscape
- Elevated planting zones
Many designs mimic natural environments such as:
- Rainforests
- Jungle streams
- Mangrove habitats
- Tropical riverbanks
The blend of water and land creates a dynamic ecosystem that evolves over time.
Why Choose a UNS Foresta Paludarium?
The Foresta range was designed specifically for nature-inspired displays.
Key Features
- Ultra-clear low-iron glass
- Rimless design
- Exceptional viewing clarity
- Premium construction
- Excellent vertical planting space
- Modern minimalist aesthetics
These features make the Foresta series ideal for creating immersive tropical landscapes.
Planning Your Paludarium Before You Start
One of the biggest mistakes beginners make is rushing into the build without a clear vision.
Before purchasing plants or hardscape, decide:
What Environment Are You Recreating?
Examples include:
- Tropical rainforest
- Jungle stream
- Waterfall scene
- Moss-covered forest floor
- Riparian habitat
Having a clear theme helps guide every decision that follows.
Understanding the Main Components
A successful paludarium consists of several key layers and zones.
Drainage Layer
Prevents waterlogging.
Substrate Layer
Supports plant growth.
Hardscape
Creates structure and visual interest.
Water Section
Provides aquatic habitat.
Plants
Bring the ecosystem to life.
Lighting
Supports healthy growth.
Each component plays an important role.
Step 1: Clean the Enclosure
Before beginning your build:
Clean the Glass
Use:
- Fresh water
- Aquarium-safe cleaning cloths
Avoid chemical cleaners or household sprays.
Starting with a clean enclosure improves visibility and ensures a professional finish.
Step 2: Create the Drainage Layer
The drainage layer sits beneath the substrate and helps prevent excess water from accumulating around plant roots.
Common Materials
- Expanded clay balls
- Lightweight drainage media
- LECA
A drainage layer is particularly important in humid tropical setups.
Recommended Depth
Typically:
- 2–5 cm
depending on enclosure size.
Step 3: Install a Barrier Layer
A mesh barrier separates the drainage layer from the substrate.
This prevents soil from migrating into the drainage section over time.
Common Options
- Fine plastic mesh
- Geotextile fabric
- Paludarium barrier mesh
This simple step greatly improves long-term maintenance.
Step 4: Add Your Substrate
The substrate supports root growth and provides nutrients.
Popular Paludarium Substrates
- Tropical bioactive substrate
- Coco fibre blends
- Sphagnum-based mixes
- Specialist paludarium soils
The ideal substrate retains moisture while maintaining good aeration.
Build Natural Contours
Create:
- Hills
- Slopes
- Elevated planting zones
This adds depth and realism.
Step 5: Design Your Hardscape
Hardscape forms the framework of the paludarium.
Common Materials
Driftwood
Creates natural roots and branches.
Dragon Stone
Excellent texture and detail.
Lava Rock
Lightweight and highly versatile.
Slate
Useful for waterfalls and ledges.
Beginner Tip
Position large hardscape pieces before adding plants.
This avoids unnecessary disturbance later.
Step 6: Create the Water Section
The aquatic portion can be as simple or elaborate as you like.
Popular Features
- Shallow pools
- Stream sections
- Waterfalls
- Pond areas
Many beginners start with a small water area occupying roughly 20–40% of the enclosure.
Water Depth
This depends on:
- Livestock plans
- Aquascape design
- Filtration requirements
Shallow water sections are often easiest to manage.
Step 7: Install Filtration (If Required)
Not all paludariums require filtration, but water features often benefit from circulation.
Options Include
- Small internal filters
- Hidden pumps
- Waterfall systems
Water movement helps:
- Prevent stagnation
- Improve oxygenation
- Maintain clarity
Step 8: Plant the Paludarium
This is where the enclosure truly comes to life.
Plant Different Zones
Foreground
- Mosses
- Pilea
- Selaginella
Midground
- Bucephalandra
- Anubias
- Ferns
Background
- Creeping Fig
- Philodendrons
- Marcgravia
Using multiple plant heights creates a more natural appearance.
Best Beginner Plants for a Foresta Paludarium
Java Moss
Hardy and adaptable.
Christmas Moss
Excellent for wood and rock.
Anubias Nana Petite
Ideal for attaching to hardscape.
Bucephalandra
Beautiful foliage and easy care.
Fittonia
Adds colour and contrast.
Pilea Species
Perfect for tropical ground cover.
These plants perform well in humid environments and are suitable for beginners.
Step 9: Add Water
Fill the aquatic section carefully.
Use
- Dechlorinated water
- RO water if appropriate
Pour slowly to avoid disturbing the substrate.
If using a waterfall or pump system, test operation before proceeding.
Step 10: Install Lighting
Lighting is critical for plant health.
Most Tropical Paludariums Benefit From
- Full-spectrum LED lighting
- 8–10 hours daily
The correct lighting promotes:
- Healthy growth
- Vibrant colours
- Compact plant development
Use a timer to maintain consistency.
Step 11: Establish Humidity
Most paludarium plants thrive in humid conditions.
Target Humidity
Typically:
- 70–90%
depending on species.
Humidity Can Be Maintained Through
- Misting
- Water features
- Enclosure design
A hygrometer helps monitor conditions accurately.
Step 12: Allow the System to Mature
New paludariums often look sparse initially.
The First Few Months
Plants establish roots.
Moss begins spreading.
Microorganisms colonise surfaces.
Humidity stabilises.
Patience is essential.
Many paludariums become dramatically more attractive after several months of growth.
Can You Add Livestock?
Yes, but only after the environment has stabilised.
Popular Beginner Options
Springtails
Excellent clean-up crew.
Isopods
Help break down organic waste.
Shrimp
Suitable for aquatic sections.
Small Fish
In appropriately sized water areas.
Always research species requirements carefully.
Ongoing Maintenance
Fortunately, most paludariums require relatively modest maintenance.
Weekly Tasks
- Mist plants if required
- Remove dead leaves
- Clean glass
- Check water levels
Monthly Tasks
- Trim overgrown plants
- Inspect pumps
- Remove accumulated debris
Regular attention prevents larger problems.
Common Beginner Mistakes
Overplanting
Leave room for growth.
Poor Drainage
Can lead to root rot.
Using Unsuitable Plants
Choose species adapted to high humidity.
Excessive Water Features
Complicated systems often create more maintenance.
Lack of Patience
A mature paludarium takes time to develop.
Simple, well-planned setups often achieve the best results.
How Long Does It Take to Mature?
A typical Foresta Paludarium develops in stages.
1–2 Months
Plants establish.
3–6 Months
Growth becomes noticeable.
6–12 Months
The enclosure begins to look mature.
12+ Months
The ecosystem reaches its full potential.
The transformation can be remarkable.
