Marina Slim Filter Zeolite Cartridge 3pk A293 - Bio-Clear Replacement for S10/S15/S20 Filters

Keep your finned friend’s home clean and healthy with Marina Slim Filter Bio Clear Ceramic Replacement Fish Filter Cartridges. These genuine replacement cartridges are designed for all three Marina Slim Filter models (S10, S15, S20) (filters sold separately) and are ideal for goldfish. Each cartridge is packed with zeolite and Ceramitek, which work together to provide optimum filtration and promote a thriving aquarium. The zeolite effectively adsorbs toxic ammonia, while the highly porous Ceramitek optimizes biological filtration. For best results, simply replace the disposable cartridge every two weeks. And remember, never replace all cartridges at once to ensure a constant presence of beneficial bacteria.
