NT Labs Ammonia Remover 240g

My clownfish tank was spiking after a filter malfunction and this zeolite-based remover pulled the ammonia down overnight. The granules have a lot of surface area for how small the bag is, and it's easy to rinse and reuse. Kept my fish safe while I fixed the real problem.

The rapid adsorption really saved my tank during a cycle crash—ammonia dropped within a day. The zeolite granules have a huge surface area, so a little goes a long way. Definitely keeping a spare bag on hand.

The granules are much finer than other zeolites I've tried, so they seem to pack more surface area into the mesh bag. Within 48 hours my tank's ammonia reading dropped from 3.0 ppm to zero, which saved my new fish from stress.
