Aquarium Ammonia Removers & Ammonia Binders
Ammonia removers bind ammonia in a non-toxic form until your biological filter can process it. Keep one around for immediate use in case of a fatal spike in ammonia, which can be caused by fish death, increased bioload, insufficient aeration or accidental death of the bacterial bed from over-use of antibiotics/over-cleaning biological media. If stressed, relocate fish to a quarantine tank until conditions stabilize, and re-establish your bacterial bed as quickly as possible.
Use ammonia removers during water preparation if you see levels in your tap water. If your aquarium is healthy and well maintained, you should only need ammonia removers for emergencies. Always monitor ammonia closely.
