Strata from Ultum Nature Systems is an innovative solution in the field of aquascaping. Made from high-quality resin, the stones and imitation driftwood are hand-modelled by professional aquascapers, giving each piece unique details and a natural look. Strata products are 100 % aquarium safe, do not harm living creatures or water quality and are colourfast. With two size variants of the Seiryu stone - type 1 with 1,29 kg and type 2 with 1,08 kg - Strata enables flexible design of aquarium landscapes.

Strata opens up endless possibilities in aquarium design. They make aquascaping easier by reducing the difficulty of hardscape design and focussing on plant growth. The combination of Type 1 and Type 2 Strata Seiryu Stones in a rimless UNS 60U-Aquarium offers additional creative freedom and expands the possibilities when designing an aquascape. With Strata, aquascaping becomes more accessible and appealing for beginners and experienced aquascapers alike.
