Effect of a Natural Adsorbent Mixture (Zeolite and Leonardite) on the Reduction of Ammonia Caused by Fish Feed

In this research, the utilization of zeolite (clinoptilolite) and leonardite mix, which are natural adsorbents that can be used to provide optimum water conditions for aquaculture, was investigated. Three groups with 3 replications were formed a commercial aquarium fish feed having 47.5% crude protein added as ammonia factor in three different concentrations (0.2 g feed/500 ml tap water, 0.4 g/500 0.6 water). Ammonia increases resulted from amounts monitored 7 days. At end period, adsorbent mixture, has water-regulating properties, experimental at ratio 1:2 (clinoptilolite:leonardite) remove ammonia, is harmful aquatic organisms, decreases determined regular intervals. NH3 value reached its highest (0.7 mg/L) stage where values measured. After it started decrease addition (mixed clinoptilolite-leonardite) lowest 6th measurement (0.07 mg/L). As result study, clinoptilolite:leonardite mixture positive influence on removal freshwater aquariums.
