Floating feed helps observe feeding at the surface; sinking feed serves different feeding habits. Floating or sinking behaviour is not the same as nutritional quality or stability in water.
Choose floating fish feed or sinking shrimp feed before factory dispatch. These configurations use different working pressures; one machine is not supplied to make both effects simultaneously or switch freely between them. Other reference specifications are the same for the same model. Actual output still depends on materials and operating conditions.
Tell us the target species, feed type, pellet size, materials, output and local electricity. Do not change working pressure or internal parts based on an online article.
