Hey, I recently set up a 20 gallon cube and i need to find a good wavemaker. Originally I set up the tank with a cheap wavemaker i got off amazon for maybe $10-11. I assumed since it was so cheap and advertised to fit a 20-30 gallon saltwater i would be fine. I was not fine. The wavemaker stirred up the sand so much there were hills half the height of my tank and lots of bare spots where the sand was completely gone from+the water was incredibly cloudy. Obviously way to strong. Does anyone have a good recommendation for a wavemaker that would fit a 20 gallon cube with about an 1 1/2-2 1/2 inch sand bed planning to do a mixed reef?
