Yes, Halamid has the unique feature that it can be used as disinfectant in presence of fish.
Fresh water raceway set up:
Halamid® is added at a concentration of approximately 10-20 ppm (10-20 g/m3). After 1 hour, flush with fresh water to remove residual Halamid®. This can be repeated up to 4 times on consecutive or alternate days.
Stagnant fresh water ponds:
Halamid® is added at a concentration of 3 ppm (3 g/m3) once a week. Water pH and hardness are two important parameters to consider in order to optimize the Halamid® concentration. As a general rule, with acidic pH, a lower concentration should be used and with increasing water hardness, a higher Halamid® concentration is recommended. Also, if using a biofilter in a recirculated water system, special attention must be taken. Please contact Axcentive or your distributor for more detailed information.
