So I had the “current USA” 660 gph wave maker for my 22 gallon reef tank … of course a month after the warranty ended it burned out like all the reviews said online… shoulda took there word for it. There’s so many options ranging from little 20$ ones all the way to 100$ ones with a complete system and timing set up. I just want something relatively simple and a bang for my buck.I don’t care for feeding times and all that really just want something my corals and fish will like. I’m attaching a few photos of my tank, I have quite a bit of rock work. You can see in the back upper left corner is my current USA wave makes, then on the front left I have a little one direction pump that still works great that I got for less than 10$. Thank you for your time and responses!
