One effort to maintain the production value of catfish is cultivation intensification, increasing stocking density from the nursery to the grow-out stage. Recirculating systems with combining of different filter types have been did in several previous studies. However, studies on the effect of different compositions of filter materials in the form of activated charcoal and zeolite during the nursery stage of catfish fry are still limited. Therefore, it is necessary to research on the combination of filter materials with different compositions using activated charcoal and zeolite for catfish fry rearing, with the expectation of maintaining fry survival and water quality in the stage II nursery media with a stocking density of up to 20 fish L⁻¹. The purpose of this study was to determine the best composition of activated charcoal and zeolite filters in the rearing water of catfish fry. The study was conducted from July to August 2025 using a Completely Randomized Design (CRD) with three treatments and three replications. The treatments consisted of stage II catfish fry rearing in a recirculation system using different compositions of activated charcoal and zeolite filter materials as follows: activated charcoal 5 g L⁻¹ and zeolite 5 g L-1 (P1); activated charcoal 2.5 g L⁻¹ and zeolite 7.5 g L⁻¹ (P2); and activated charcoal 7.5 g L⁻¹ and zeolite 2.5 g L⁻¹ (P3). The catfish fry used had an initial length of 2.0±0.5 cm and were stocked at a density of 25 fish L⁻¹ for 30 days. The results showed that treatment P2 produced the best performance, with a temperature of 28.15±0.04 °C, pH 6.55±0.17, ammonia 0.064±0.006 mg L⁻¹, dissolved oxygen 4.11±0.63 mg L⁻¹, turbidity 1.88±0.14 NTU, survival rate 90.15±2.13%, absolute length growth 4.33±0.07 cm, absolute weight growth 3.93±0.12 g, and feed conversion ratio 0.33±0.02. The combination of 2.5 g L⁻¹ activated charcoal and 7.5 g L⁻¹ zeolite (P2) was shown to be the most effective, instead for maintaining water quality and ensuring the survival rate of catfish fry.
