Home About Us Feedback Add Us Description API Pond Ammo Lock (formerly PondCare Ammo-Lock) instantly detoxifies ammonia from fish waste, tap water, uneaten fish food, and decomposing plants and algae. Use as a water conditioner to instantly make fresh pond water for plants and fish, or to remove unsafe ammonia levels in existing water. * Detoxifies ammonia * Instantly makes pond water safe for fish * Eliminates ammonia stress and promotes healthy gill function * Use whenever ammonia is detected Ammo Lock has been uniquely developed to eliminate the toxic effects of chlorine, chloramine and ammonia that may be present in municipal water used to fill ponds. Fish waste, decomposing algae, plants and uneaten fish food produce ammonia. Ammonia, which is a colorless and odorless toxic chemical, is the number one killer of pond fish. Ammo-Lock also detoxifies harmful levels of ammonia that can occur in pond water from overfeeding and overstocking of fish. Ammo Lock is a patented formula that instantly neutralizes both chlorine and chloramine and effectively "locks up' any potential ammonia or immediate ammonia up to 5 ppm per dose. Although ammonia will still be present in pond water, converts the ammonia to a form that is nontoxic to aquatic life; this nontoxic form actually serves as a source of nutrition for nitrifying bacteria in the biological filter. Ammonia build-up can occur whenever starting a new pond, before biological filtration becomes active, or when there is inadequate biological filtration.
