NEWA Aqua CERAMIC HI-Q are ceramic elements with an extremely porous structure suitable for maximizing the performance of the biological filter. NEWA Aqua CERAMIC HI-Q optimizes filtering in newly set up aquariums and improves it in those already in operation. Compared to standard ceramic elements, the efficiency of the biological filter doubles for the same volume. The practical resealable and waterproof jar keeps its characteristics unaltered over time.
