High quality activated carbon especially developed for salt water tanks.
You will see the difference significantly on your corals.
Put it in a mesh bag in a passively flown filter bypass or in a nylon stocking on top of the ZEOvit® in the ZEOvit® filter. Rinse the carbon briefly with hot tap water before use.
The result is a better polyp extension. It adsorbs toxins, toxic compounds and yellowing compounds and also proteins.
Keeps your tank water crystal clear.
Use 1 L Korallenzucht activated carbon for 1000L water.
Completely replace every 30 days.
