The research was planned to determine the usability of natural diatomite in aquaculture conditions. The effects of using two different sizes and three different amounts of raw diatomite mineral on aquaculture water parameters for freshwater species and their usage characteristics were investigated. The research was carried out in two separate stages. In the first experimental setup, the effects of two different sizes (100–125 µm powder and 3–5 mm granule) and three different amounts of diatomite (2, 4, 6 g/0.5 L freshwater) on water parameters were investigated. At the end of the first stage, a second experimental setup was prepared to determine the possibility of diatomite abrasion and mixing into water. Based on the ideal size and amount of diatomite determined in the first stage, the diatomites were placed in the WP-300F internal filter (with filter sponge), and a trial setup was formed with two groups in three repetitions. As a result of this research, it was determined that 3–5 mm diatomite, at a rate of 6 g per 0.5 L of water, can be recommended to be used for filtration as filtration material and substrate material for freshwater aquaculture applications.
