Safety Stop is a simple and effective way to help protect your fish from serious unwanted disease outbreaks caused by external parasites, and bacterial and fungal infections. New fish are often the source of infectious diseases that can wipe out an entire aquarium. Be proactive and give your fish a Safety Stop bath to significantly lower the risk of introducing deadly diseases. 


While there is no substitute for extended quarantine of new fish in a separate hospital tank, there may be times when this is not possible or practical. Use Safety Stop as a basic safety measure before introducing the new fish into your main aquarium or into the quarantine tank. 


Recommended Use

  • Take fish from store directly home without delay. Acclimate fish to the same temperature and pH of the aquarium before performing the Safety Stop bath. 
  • While your fish is acclimating, prepare the two baths: into clean, non-metallic containers (i.e., a plastic or glass bucket), add one gallon of water directly from the aquarium into each bucket. Monitor each bucket for temperature changes.
  • With scissors, cut the edge of the product packages and pour PART A into the first container and PART B into the second container. Gently agitate both solutions with an air stone. Leave the air stones in the container to oxygenate the water while fish is in the bath.
  • Remove the fish to be treated from acclimation water and place in bath PART A for 45 min (30 min if fish has been shipped overnight within the last 72 hours). Keep a loose cover on bath to make sure fish doesn’t jump out.  Carefully watch the fish for signs of stress during the entire treatment process. Signs of stress include heavy breathing, erratic swimming, rolling, etc. If fish shows signs of stress reduce time and put them immediately into PART B bath.
  • After Part A, transfer fish to Part B bath for 45 min. Continuing to watch for signs of stress. If signs of stress occur, remove before treatment is over, and transfer to quarantine tank or prepared aquarium. Do not put bath water into aquarium. After treatment B is over net fish into aquarium.
  • Observe fish after introduction to your aquarium to make sure tank mates are not harassing the fish. It is a good idea to feed the tank simultaneously while introducing the new fish to keep the resident fish occupied. Keep light levels low for 24 hours after introduction.

Product Questions

What conditions does this treat? Will I see parasites drop off fish during the treatment?
Question by: Paige on Jul 2, 2023, 8:36 AM
This will treat or provide relief from several parasites or infections. Parasites such as flukes will fall off the fish. This is not a cure for parasites, but will help reduce external parasite loads to allow time for proper treatments.
