Each piece of WIO Black Tree Trunk is carefully selected for its exceptional character. Its deep purplish black color brings a striking visual contrast to your aquarium, creating an original and aesthetic decor. With its realistic tree trunk structure and exposed roots, it perfectly imitates the natural decor of tropical rivers, offering your fish a harmonious and soothing environment.
This natural wood is not only beautiful but also safe for all your aquatic animals. Although this wood naturally releases tannins, these are harmless and faithfully reproduce the conditions of wild aquatic habitats such as those of the Amazon. To minimize this effect, simply boil or soak the wood for a few weeks before installation. Additionally, this wood can slightly reduce the pH of your water, which is ideal for recreating an authentic tropical environment. Regular monitoring of the pH is recommended.
When you first install it, you may notice a slight whitish deposit called saprolegnia, but don't worry: it disappears naturally in a few weeks. You can speed up the process by gently brushing the affected areas. Once this is over, your decor will remain stable, beautiful and durable, requiring very little maintenance to maintain all its natural charm.
Available in various sizes (10-40 cm), it is suitable for different types of aquariums, paludariums and terrariums. Its integration is simple and effective, and it can be stabilized with stones or fasteners until it becomes totally submerged.

JBL ProHaru Universal allows you to glue decorations, windows, technical parts, seal leaks in the aquarium and terrarium. This glue can be used underwater and out of water.
Blyxa japonica from Tropica is a unique aquarium plant. With its leaves shaped like soft strands that undulate in the current, it immediately gives a natural and lively look to the decor.

Cultivated in vitro, it arrives without algae, snails, or pesticides , and integrates easily into aquascapes of all sizes, even nano. Moderately demanding, it appreciates intense lighting , a good substrate, and a CO2 system if possible. A plant that is both graphic and functional, perfect for adding movement and texture.
Rotala rotundifolia 'Blood Red' is undoubtedly one of the most spectacular plants for adding color to an aquarium. A native of Asia, this variety boasts a deep, vibrant red color that creates a striking contrast alongside light green plants. Easy to maintain, it thrives even in moderate light and nutrient conditions, although strong lighting and an optimized CO2 system are recommended to reveal its full potential. It grows tall, with gently arching stems that form a dense, bushy structure. Easily trimmed, it can be used to create colorful, dynamic, and modern displays in any type of tank.
