How quickly can I add my fish after I put in the detoxifier?

Aquascape Detoxifier goes to work immediately, removing chlorine, ammonia, chloramine and toxic heavy metals. Although the water is technically safe, the pond is not biologically mature and new fish should be added in stages.  You should  acclimate fish to the temperature of the water by floating them for 20 minutes or slowly adding water to the bag or container containing the fish, before releasing them into the pond.
