ATI Hydro Sponge Stackable Kit #3

Increase the biological and mechanical filtration capabilities by stacking identical size sponges on top of each other with one lift tube and a single airline. Conserve valuable tank floor space while dramatically increasing filtration capacity. The modular design allows each sponge unit to attach securely and easily. Increased surface area for colonization of nitrogenous bacteria greatly increases the effectiveness of biological filtration and the amount of bio load it can handle. When things go wrong and out of balance, ammonia and nitrate can suddenly sky rocket causing mortality of fish and inverts. A greater bio capacity is the best safeguard in case of accidents. The ease of how these units connect is amazing. Just push and turn and they are securely fastened.

1. Ideal for tall aquariums and odd shaped aquariums

3. Saves cost of buying additional filters
4. No additional airlines, pumps, or powerheads
