Glass Pearls ZOLUX Perełki szklane Seszele – decorative aquarium substrate beads

ZOLUX Perełki szklane Seszele are smooth glass pearl beads designed as a decorative substrate for aquariums and terrariums. These inert glass beads provide a stable, non-reactive base that does not leach minerals or alter water chemistry, making them suitable for both freshwater and saltwater setups. Their uniform spherical shape and polished surface create a clean, reflective look that enhances visual contrast with plants, rocks, and ornaments while helping to anchor lighter decor elements.

Advantages

The glass material is chemically neutral and resistant to degradation, so it will not affect pH, hardness, or other water parameters. The consistent size and finish of the beads make them easy to rinse and arrange, and their smooth surface resists debris buildup compared with rougher substrates. Because they are non-porous, these beads do not absorb dyes or odors and are easy to maintain over time.

Suitable for (tasks / use cases)

• Decorative substrate for freshwater aquariums
• Decorative substrate for marine and reef displays
• Terrarium floor covering for humidity-stable designs
• Accent layer to highlight plants, driftwood, or ornaments
• Anchoring lightweight plants and decorative items

Key specifications

• Material: soda-lime glass (inert and non-reactive)
• Shape: spherical beads with polished surface
• Color: transparent/clear (visual reflective finish)
• Intended use: decorative aquarium and terrarium substrate
• Chemical behavior: non-porous and does not alter water chemistry

How to use

Before adding to a tank, rinse the glass pearls thoroughly under running water until the rinse water is clear to remove any dust from packaging. Spread an even layer on the bottom of the aquarium or terrarium; typical depth depends on purpose but often ranges from a single layer to several centimetres when anchoring plants. Place plants, stones, and ornaments on top of the beads and adjust positioning as needed. Monitor the display during the first days to ensure no fine particles cloud the water; perform partial water changes if necessary to clear residual dust.

Usage recommendations

For biological filtration needs or planted aquariums that require root substrate and nutrient exchange, combine these glass pearls with a dedicated plant substrate or use them as a decorative top layer. Avoid placing sharp-edged decorations directly onto the beads to prevent chipping. Regular gentle vacuuming around decorations will help keep the beads clean without removing the entire layer.
