PRODAC Bioclaro 32x20 h 6.5 cm Aquarium Filter

The packaging contains two sponges, the first one with fine porosity (30 ppi, blue) and the second one with coarse porosity (10 ppi, black), for biological and/or mechanical filtration in fresh and marine water aquarium and water terrariums. Use: - Rinse before using. Insert the black sponge in the water inlet of the filter, to hold larger particles. Insert the blue sponge in the intermediate stage of the filter. Both sponges must adhere the filter walls. Water must go through the sponges. Rinse the sponges every 3 months using only tap water and replace them every 12 months. We advise washing one sponge at a time, waiting 7 days before washing the other one, to avoid destroying the bacterial fauna. Specifications: - Dimensions: L32xH20xW6,5 cm
