I modified the Resun Waver 15000 WaveMaker, 6000-15000 l/h, by installing a different propeller, which significantly increased its performance. I also modified the SunSun JVP-102, 5000 l/h, by replacing the propeller and changing the metal shaft to a carbon one, which improved its performance and eliminated the noise that was present with the metal shaft.
