Wave-making pump for marine tanks, coral reefs, and freshwater. Key features include; regulating water flow strength, creating flows of varying intensity for soft and hard corals, support base can be rotated 360°, pump can be tilted up and down up to 180°, high-resistance magnetic support, suitable for glass up to 15mm thick, allows angle adjustment. Can be used to lift sediments from the bottom of the tank to improve filtration, contributing to cleaner and clearer water.
