Aquarama One (1) x Replacement Nitrate (Green) Filter Sponge to fit Juwel COMPACT System

This was for my son with his Christmas gifts so again I had to wait for his verdict. As before he was very pleased with this product. He always uses Juwel products and asks for them by name when he requests any of these products he needs for his aquarium.He says the Juwel products are always of excellent quality and are very reliable.
