Pure Pond 500ml Slow Release Bacteria Gell Balls

The Evolution Aqua Pure Pond bacteria gell balls are made from a biodegradable polymer, and crammed full of bacteria that are slowly released when they are needed most.When you introduce the Evolution Aqua Pure Pond bacteria gel balls into the biological chamber of your Nexus, they become one with moving bed, agitating alongside the K1 media, just waiting to smooth out the peaks and troughs of the Ammonia/Nitrite cycle.
